List of sea animals with tentacles. Marine inhabitants and interesting facts about them. Undersea world

Life on planet Earth originated in the ocean. It was from the water that the first animals came to land. are distinguished by enormous species diversity. All marine representatives of the organic world live in the water column and on the ocean floor. Scientists count more than 150 thousand inhabitants of the oceans and seas, including plant and animal organisms that inhabit the sea and ocean spaces of the planet.

Inhabitants of the seas and oceans: diversity and living conditions

Everyone knows that the aquatic environment is strikingly different from the land-air environment. Significant depths are excommunicated by low temperature and high pressure. Living at great depths, they practically do not see sunlight, but despite this variety of life forms, it is amazing.

Almost all useful substances that are necessary for the life of the inhabitants are dissolved in water. depths of the sea The water space warms up very slowly, but heat transfer occurs over a long period of time. Of course, at significant depths the temperature changes almost imperceptibly. An important component for all creatures in the water column is the presence of oxygen. In the absence of free oxygen, hydrogen sulfide is formed, this is typical for the Black Sea and Arabian Sea.

Inhabitants of the seas and oceans For full development, protein is required, which is found in large quantities in

Flora of the oceans and seas

Sea plants contain chlorophyll, a green pigment. With its help, the energy of the sun is accumulated. Water splits into oxygen and hydrogen, then hydrogen enters into a chemical reaction with carbon dioxide from the surrounding aquatic environment. After this, starch, sugar and proteins are formed.

At relatively shallow depths, rich vegetable world. The inhabitants of the deep sea find food for themselves.

One of the most common algae is kelp; their length can reach six meters. It is from this plant that iodine is obtained, and they are also used as fertilizer for fields.

Another brightest inhabitants of the seas and oceans (mainly southern latitudes) are marine organisms that are named - But they should not be confused with plants, these are real animals. They live in large colonies, attaching themselves to rocky surfaces.

Plants need sunlight, so plants are found at least 200 meters deep. Only live below inhabitants of the seas and oceans who do not need the light of the sun.

Sea creatures

Previously, it was believed that no one lives below six kilometers of depth due to the high pressure that the water column exerts on living beings. But scientists conducted deep-sea studies that confirmed the hypothesis that at great depths there are various species (crustaceans, worms, etc.). Some deep sea inhabitants of the seas and oceans periodically rise to a depth of up to a thousand meters. They do not float higher, because... Closer to the surface, large differences in water temperature are observed.

Many deep-sea inhabitants who spend their entire lives at the bottom have no vision. But some parts of their body have special flashlights. They are needed to escape predators and to attract potential prey.

Animals of the seas and oceans feel comfortable in their environment, many of them do not need to adapt to seasonal environmental changes.

A special role in the life of many marine inhabitants is played by single-celled organisms, which are called plankton and move with the help of currents. They feed on many fish, which constantly follow them. With increasing depth, the amount of plankton decreases sharply.

Scientists have long proven that inhabitants of the seas and oceans live in all water layers. These animals and plants are distinguished by great species diversity, as well as unusual shapes and colors. You can endlessly admire the various species of fish, corals and other marine inhabitants of the most bizarre forms that seem to be aliens from another planet and admire the perfection of nature.

And in conclusion, I bring to your attention an unusually interesting documentary dedicated to different entitled “The Most Dangerous Animals. Depths of the sea." Take a look, it will be interesting!

Seas and oceans are the cradle of life on Earth. According to some theories, all life on the planet originated in water. The sea resembles a huge metropolis, where everything lives according to its own laws, everyone takes their place and performs a very important function. If this order, which has formed into a harmonious mosaic, is disrupted, then this city will cease to exist. Therefore, it is important to know about the riches of the animal world. Find out who the sea inhabitants are, photos with the names of the most common species and Interesting Facts You can read more about their lives below.

All living creatures inhabiting the sea are divided into several categories:

animals (mammals);
fish;
algae and plankton;
deep-sea fauna;
snakes and turtles.

There are animals that are difficult to classify into a specific group. For example, sponges or sponges.

Marine mammals

Scientists have discovered more than 125 species of sea-dwelling mammals. They can be divided into three main groups:

Walruses, fur seals and seals (order pinnipeds).
Dolphins and whales (order cetaceans).
Manatees and dugongs (order of herbivores).
Sea otters (or otters).

The first group is one of the most numerous (more than 600 million individuals). They are all predators and eat fish. Walruses are very large animals. Some individuals reach a weight of 1.5 tons and grow up to 4 m in length. Given their size, the agility and flexibility of walruses is amazing; they move easily on land and in water. Thanks to the special structure of the pharynx, they can spend a long time in the sea and will not drown, even if they fall asleep. The thick brown skin lightens with age, and if you see a pink, even almost white, walrus, you know that he is about 35 years old. For these individuals this is already old age. Walruses are not confused with seals only due to their distinctive feature - tusks. Measurements of some of the largest tusks showed almost 80 cm in length and a weight of about 5 kg. The walrus's front fins end in fingers - five on each paw.

Seals live in the Arctic and Antarctic, so they can withstand extremely low temperatures (down to - 80˚C). Most of them do not have external ears, but they hear very well. Seal fur is short but thick, which helps the animal move underwater. It seems that seals on land are clumsy and defenseless. They move with the help of their forelimbs and abdomen; their hind legs are poorly developed. However, they move briskly in the water and swim excellently.

Fur seals are very voracious. They eat 4 - 5 kg of fish per day. The leopard seal, a subspecies of seals, can catch and eat other small seals or penguins. The appearance is typical of most pinnipeds. Seals are much smaller than their fellow cats, so they crawl on land using all four limbs. The eyes of these sea inhabitants are beautiful, but it is known that they see poorly - myopia.

Dolphins and whales are related to each other. Dolphins are one of the most unusual creatures on the planet. Their distinctive features:

The absence of ears, nose, small eyes and at the same time a unique echolocation that allows you to accurately determine the location of objects in the water.
A bare, streamlined body, without signs of fur or scales, the surface of which is constantly renewed.
Voice and rudiments of speech, allowing dolphins to communicate with each other in a school.

Whales are giants among mammals. They feed on plankton or small fish and breathe through a special hole called a “blowhole.” During exhalation, a fountain of moist air from the lungs passes through it. Whales move in the water with the help of fins, the size of which differs among different species. The blue whale is the largest animal that ever lived on Earth.

The most popular types of sea fish

The second largest group of marine inhabitants includes the following species:

Cod (blue whiting, cod, navaga, hake, pollock, pollock and others).
Mackerel (mackerel, tuna, mackerel and other fish).
Flounder (flounder, halibut, dexist, embassicht, etc.).

Herring (Atlantic menhaden, Atlantic herring, Baltic herring, Pacific herring, European sardine, European sprat).

Garfish (garfish, medaka, saury, etc.).
Sea sharks.

The first species lives in the seas Atlantic Ocean, comfortable conditions for them are 0 ˚ C. Its main external difference is the mustache on its chin. They live mainly on the bottom, feeding on plankton, but there are also predatory species. Cod is the most numerous representative of this subspecies. It reproduces in large numbers - about 9 million eggs per spawning. It is of great commercial importance, since meat and liver have a high fat content. Pollock is a long-lived member of the cod family (lives 16 - 20 years). It lives in cold waters and is a semi-deep-sea fish. Pollock is caught everywhere.

Mackerels do not lead a bottom-dwelling lifestyle. Their meat is valued for its high nutritional value, fat content and a large amount of vitamins.

In flounders, the eyes are located on one side of the head: right or left. They have symmetrical fins and a flattened body.

Herring fish are pioneers among commercial fish. Distinctive features are no or very small teeth, and almost all lack scales.

Sargan-like fish are elongated in shape with long, sometimes asymmetrical jaws.

The shark is one of the largest marine predators. Whale shark- the only one that feeds on plankton. The unique abilities of sharks are smell and hearing. They can smell a smell from several hundred kilometers away, and their inner ear is capable of detecting ultrasound. The shark's powerful weapon is its sharp teeth, with which it tears the victim's body into pieces. One of the main misconceptions is the idea that all sharks are dangerous to humans. Only 4 species pose a danger to people - bull shark, white shark, tiger shark, and whitetip shark.

Deep sea fauna

There are a great many inhabitants of the seabed, but their sizes are microscopic. These are mainly the simplest single-celled organisms, coelenterates, worms, crustaceans and mollusks. However, in deep water there are also fish and jellyfish that develop the ability to glow. Therefore, we can say that there is not absolute darkness under the water column. The fish that live there are predatory and use light to attract prey. One of the most unusual and terrifying, at first glance, is the hauliod. This is a small black fish with a long whisker on the lower lip, with the help of which it moves, and with terrible long teeth.

One of the most recognizable representatives of the mollusk order is the squid. It lives in both warm and cold seas. The colder the water, the paler the color of the squid. The change in color saturation also depends on the electrical impulse. Some individuals have three hearts, so they have the ability to regenerate. Squids are predators; they feed on small crustaceans and plankton.

Shellfish also include oysters, mussels, and scallops. These representatives have a soft body, closed in a shell of two valves. They practically do not move, bury themselves in silt or live in large colonies, located on rocks and underwater reefs.

Snakes and turtles

Sea turtles are large animals. They reach 1.5 m in length and can weigh up to 300 kg. Ridley is the smallest among all turtles, weighing no more than 50 kg. The front legs of turtles are better developed than the hind legs. This helps them swim long distances. It is known that sea turtles appear on land only to procreate. The carapace is a bony formation with thick scutes. Its color ranges from light brown to dark green.

When getting their food, turtles swim to a depth of 10 meters. They mainly feed on shellfish, algae and sometimes small jellyfish.

Sea snakes exist in 56 species, grouped into 16 genera. They are found off the coast of Africa and Central America, in the Red Sea and near the coast of Japan. A large population lives in the South China Sea.

Snakes do not dive deeper than 200 meters, but they can remain without air for 2 hours. Therefore, these underwater inhabitants do not swim further than 5 - 6 km from land. Crustaceans, shrimp, and eels became their food. The most famous representatives sea snakes:

The Ringed Emidocephalus is a snake with poisonous teeth.

Microcephalus is a small (70 - 80 cm) snake with a small head, a thick rear part and large triangular scales that cover the entire body.

Dubois – sea snake, living on the coast of Australia. Thanks to its light brown color with small spots, it is well camouflaged. Strikes terror into local residents and divers, since its venom can be compared in strength to that of a cobra.

Snakes rarely live alone, usually forming large aggregations.

Marine life, their photos with names, habitats and unusual facts life are of great interest to both scientists and amateurs. The sea is a whole Universe, the secrets of which people will have to learn for many more millennia.

Everything inaccessible enchants. And what could be further from a person than the ocean floor? Sea creatures are so different from terrestrial creatures. I really want to know more about them. What do they eat? How do they live and protect themselves? There is so much that I really want to know.

Looking at the surface of the water, it is difficult to imagine the diversity of life that lurks below. But these are not only animals, fish and plants. The basis of the marine food chain is plankton.

What is plankton?

The entire world of marine animals would cease to exist without him. Plankton are microscopic creatures that are invisible to the naked eye. Their design does not allow them to move arbitrarily in the water. The position of this creature depends on the current, they are not able to resist it.

There are two types of plankton in nature:

zooplankton, which is formed from living organisms;
phytoplankton are special marine plants.

The latter gives the water a slightly green tint. There is so much plankton in the water that in one liter of it millions of these creatures are found. Moreover, they not only serve as food that all marine life eats, but also participate in the restoration of oxygen in the water.

Transparent antiquity, or Why the jellyfish is interesting

These inhabitants of the deep sea consist of 90 percent water. Moreover, jellyfish appeared on Earth so long ago that their distant ancestors witnessed the life of dinosaurs.

Some species of these animals have poison that can cause a burn on the skin of a person or even kill. For example, the box jellyfish is extremely dangerous. It kills as many people a year as do not die from all other inhabitants of the seas and oceans. The bite of this jellyfish kills in three minutes, and it moves at a speed of 2 m/s. It is difficult to escape from it, and surviving a bite is almost impossible.

The range of sizes of these creatures of different species is striking. The smallest of them are the size of a pinhead, while the largest have a dome with a diameter of two and a half meters, and their tentacles grow up to fifty meters.

Because jellyfish for the most part die after reproduction, their life span is very short. Very rare specimens live in nature for more than two years. Most often they are given only a few months. In captivity, these marine inhabitants can live for quite a long time.

Boneless Giant - Octopus

These sea creatures are very interesting for children due to their unusual structure. After all, octopuses have tentacles instead of legs, and they have no bones at all. Thanks to the latter fact, this creature can easily squeeze into a tiny hole, the diameter of which is only one centimeter.

Here are some interesting facts about sea creatures - octopuses:

the blood of these creatures is blue;
they have three hearts at once;
octopuses are deaf;
they can separate any part of the body, which will then grow back;
octopuses easily change their color to adapt to their environment;
they turn completely white with fear;
in order to confuse the pursuer, these animals throw out a cloud of ink.

Some types of octopuses are extremely poisonous. For example, the blue-ringed one, which has a diameter of about 3-4 cm and weighs only 100 g. Its bite stops swallowing after 5 minutes. And after 30 minutes the person suffocates. Moreover, there is no effective antidote yet. The only way to save a person is to perform artificial ventilation until the poison stops working.

Wonderful cetaceans

These inhabitants of the deep sea are mammals. Even though their bodies are quite similar to those of fish, they are still very different. The main difference is in the way of breathing. Marine fish breathe air dissolved in water. Cetaceans lack this ability. They need to breathe air from the atmosphere. For this purpose, they are forced to float to the surface. There they inhale and exhale. The latter is visible as a fountain of air with no big amount water.

These mammals give birth to their young in water. Therefore, the mother immediately after birth pushes to the surface for the first breath.

The biggest marine mammals are blue whales. By the way, they are the largest animals on Earth. The dolphin is the smallest of the cetaceans.

A little about different types of whales

Blue whales are already born giants. Their length reaches 8 meters, and they weigh about 3 tons. The largest female of this whale that was caught weighed 190 tons.

Most cetacean species prefer the sea. The exception is humpback whale, which lives near the coast. There are cases when these animals were spotted in bays and rivers. These sea creatures love to perform acrobatic stunts. They emerge from the water and dance gracefully.

These species of whales do not have teeth. Instead, the mouth is filled with horny plates called baleen. Through them, mammals filter plankton, which they feed on.

Such sea predators as sperm whale, feed on cephalopods and fish. They are wonderful divers. They can dive for squid to depths of up to two kilometers. While searching for prey, sperm whales are capable of not breathing for about two hours.

Another carnivorous mammal - killer whale. She has proven herself to be a brutal killer. But there are no documented facts about attacks on people.

Amazing whale narwhal differs from all others in having a long straight tooth. Despite their menacing appearance, they are very friendly.

The most famous cetaceans are dolphins. They are incredibly smart and quick-witted. They are easy to tame and train. By the way, they have a well-developed vocal apparatus and produce a large number of different sounds.

Unusual fish

The names of sea creatures such as: sunfish, needlefish, flounder and swordfish. The first of them floats near the surface of the sea. This makes its fin visible above the water. From a distance it looks like a shark fin. However, it is completely harmless.

Needlefish has a unique way of hunting. She hides behind other fish and approaches the prey. At the right moment, she instantly sucks the poor thing into her mouth.

Angler invented his own style of hunting. This predator shakes its antenna with a growth that resembles a worm in appearance. The fish “bite” at him, and he eats them.

A flying fish invented a way to escape from enemies. She learned to glide over the sea. This is facilitated by its well-developed lateral fins.

Fish with eyes on one side

Flounders can have eyes only on the right or left side of the body. It all depends on the species. These sea fish are unique in that their eggs do not contain fat. This causes the eggs of most flounder species to float near the surface.

These fish do not like deep water. They live mainly near the coast. Rare individuals swim to depths of more than one kilometer.

Interestingly, flounder species are differentiated by mouth size. They can be largemouth or smallmouth. The first of them are predators, whose mouth is symmetrical and “equipped” with teeth on the sighted and blind sides of the body. Examples of such fish are halibut and flounder. They feed mainly on worms and small fish, mollusks and crustaceans, as well as brittle stars.

Warlike Swordfish

This name arose due to the unusual xiphoid process, which is located on its upper jaw. This is not the only feature. Swordfish have no scales. All this, as well as a sickle-shaped tail and a special shape of fins, allows it to be the fastest creature on Earth. Swordfish can swim for a long time at a speed of about 130 km/h.

For such speeds you need space. Therefore, it can only be found in the open ocean.

Swordfish fry feed on plankton. But after they grow to 2 cm, they begin to hunt. Their prey is small fish. At the same time, they begin to develop a sword-shaped appendage. The fry grow very quickly, and after a year their length is about 50 cm.

The predator feeds on everything that comes in its way. And the size of the prey doesn't matter. With her sword she strikes the sea dweller. There are known facts that pieces of shark bodies were found in the stomachs of caught fish.

A little about predators living in the seas

The most famous sea predators are sharks. They were able to survive the dinosaurs. Their sizes depend on the species. The largest of them reach 10-12 meters. Moreover, not all types of sharks are predators. There are some that feed on plankton. Sharks move very quickly due to their streamlined body shape. Unlike fish, they lay eggs, not eggs. These eggs may be attached to the bottom or algae. And some species of sharks carry eggs inside themselves. Shark eggs hatch completely viable.

Prominent representatives of this family: brindle and gray shark. The first one is painted in a very original way. So much so that it resembles a tiger. She doesn't swim far from coastline. Its diet consists of fish and crustaceans, birds and small mammals.

Gray shark also does not swim far into the sea. She looks for fish and crustaceans in the shallows. It does not purposefully attack people. But a person running in panic can be mistaken for a victim.

Other unusual predators - stingrays. Their bodies are strongly flattened and resemble a scarf. When the stingray lies on the bottom, it is perfectly camouflaged. His swimming style resembles flying in the water column. Some species of stingrays are poisonous. They have a spike on their back that releases a poisonous substance. And their mouth is on their belly. Moreover, it is equipped with a large number of sharp teeth.

Leopard seal is formidable and dangerous predator. This seal got its name because of its color, similar to the spots of a leopard. It feeds on penguins and other warm-blooded animals of the Antarctic. But the leopard seal does not mind picking up carrion or feasting on squid or fish.

Amazing facts about sharks

Only the facts are listed here. There is so much made up about marine life that we need to get more reliable information.

These creatures are excellent at recognizing odors. Blood has a special place in this. They feel it even at very low concentrations.
If the victim does not smell of blood, then the shark perceives its movement. To do this, it has a lateral line, consisting of cells sensitive to vibrations.
Baby sharks are born with a large number of teeth and can immediately begin to get their own food.
By the way, about teeth. In sharks they are attached to the gums, not the jaws. Moreover, they form from 4 to 6 rows. Her teeth grow throughout her life, moving forward to replace the lost ones.
The force of pressure of each tooth of a white shark is the same as if a load of 3 tons pressed 1 cm 2.
These gluttons eat everything. Moreover, even inedible things are found in their stomachs. But this is not the most surprising thing. A shark can hold food in its stomach without digesting it for several weeks.
The entire skeleton of a shark is made of cartilage. There is not a single bone in it.
This sea creature does not have a swim bladder. This feature forces the shark to constantly move so as not to drown.

Enchanting reefs

Corals are formed from small animals. Although many believe that these are marine plants. Coral reefs are home to many animals and plants. This is due calm sea inside them. In addition, they have a lot of light and warmth. The inside of the reef is teeming with life, while the outside is empty and bottomless.

The largest coral has a length of more than two thousand kilometers. It is located off the coast of Australia.

Underwater volcanoes sometimes rise to the surface of the ocean. Regularly shaped coral reefs can form around such craters. They form coral islands which are called atolls.

The sea is always a mystery. Endless and deep, which humanity has been unraveling for centuries and cannot solve in any way. Ebb and flow, Bermuda triangles and the nature of the storms is all, of course, a mystery. But more people were and continue to be interested in marine life - from small fish to a huge whale. Each of the species of inhabitants of the underwater world is, in fact, a separate people, professing their own traditions and protecting their tribe in all possible ways.

One has only to listen to the stories of divers: even the least experienced of them retains in their memory some interesting fact about marine life and can describe for hours amazing landscapes sea depths.

People who find themselves in the underwater kingdom or a specially equipped observation aquarium are touched by everything: living corals, colorful baby fish (if you stay away from them) and even evil sharks - some of them, as it turned out, are not at all bloodthirsty. But for many years now, clever dolphins have remained a hit with human sympathies.

Intelligent, sociable, capable of empathy

Oceanologists who know a lot about sea creatures have long come to the conclusion: dolphins are the most perfect and unique of them. Firstly, no one among the citizens of the underwater state is closer to the person. Moreover, dolphins are very similar to us: they love to have fun and come up with ways to diversify their underwater and above-water leisure (for example, as fun, they blow air bubbles and rings underwater, using their blowhole as a tool); They feel responsible for weakened or in trouble relatives, will never abandon an elderly or injured dolphin to the mercy of fate, and are always close to a female whose birth process is complicated. In all these cases, they are not just present, but help and support.

Dolphin: doctor or medicine?

Dolphins are the friendliest for children; they can become swimming coaches, nannies in the pool, and a cure for mental disorders, and a whole range of unpleasant diseases: cerebral palsy, autism, depression. By the way, now adults are not ashamed to undergo dolphin therapy: it is both pleasant and effective.

Dolphins rank third among mammals in terms of mental abilities.

The intellectual abilities of these cute mammals are supported by their habit of using available means during hunting, for example, protecting their nose from prickly fish with a sea sponge.

In the dolphin's mouth there are hundreds of small teeth, which he never uses for their intended purpose one hundred percent - with their teeth, dolphins only capture prey, but never chew.

The height of a dolphin's jump above the water can reach 6 meters, and the maximum dive depth can be up to 305 m, but only during hunting. Dolphins usually live at a depth of 2-10 m.

Miracle Yudo Fish-Whale

No less remarkable are the largest marine inhabitants - whales. At the mere mention of these giants, many interesting facts about maxi-sized marine life emerge.

Just because a whale is huge doesn't mean it's slow. In the waves, whales play and frolic like children, demonstrating graceful (almost graceful) diving.

Whales are capable of diving to enormous depths - up to 1000 m. And the pressure is strikingly different from the pressure on the surface. So whales adapt: during a dive, their pulse slows down to ten beats per minute, ensuring blood flow only to the heart and brain. The skin, fins and tail remain “disconnected” from the energy supply.

The pattern on a whale's tail is as individual as a person's fingerprints.

There are only two species of mammals in the world that can sing. This is a man and... a whale. The shortest whale song lasts about six minutes, and the longest lasts half an hour. Both males and females sing. At the same time, it has been noticed that “female” whales often indulge in singing; the songs are intended for their children. And what is most surprising is that whales completely lack vocal cords.

Another interesting fact about marine whales that cannot be ignored: these giants are constantly busy analyzing the sounds made by the sea. Their hearing is well developed, but their sense of smell is absent and their vision is atrophied.

"We are funny jellyfish"

Many representatives really have a very “cheerful” coloring, simply carnival-like. Having such a bright appearance, they cannot help but defend themselves, which is why they are poisonous.

Perhaps the following fact is not entirely interesting about marine life, but very instructive: when getting to exotic latitudes, you need to be wary of the jellyfish called sea wasp Flecker. She's a killer. It accounts for one death every year. Its poison acts as a powerful cardiac paralytic. The only one effective method escape from the deadly substance - nylon tights. This item of women's clothing is very popular among Queensland fishermen.

And in the pool Caribbean Sea Farmers have learned to use jellyfish venom to great advantage - with its help they poison rats and other harmful rodents that cause damage to the farm.

The main thing is the pattern on the shell

The most incredible facts about marine life do not arise without human help. And the point is not that he composes them - he even provokes them. In the good sense of the word.

For example, heikegani crabs, living off the coast of Japan, survived and developed their population only thanks to the pattern on the shell. He very much resembles the stern face of an angry samurai.

When a crab with such a pattern fell into a fishing net, it was reverently released, sincerely believing that a restless samurai soul had settled in this creature.

Thanks to the belief of Japanese fishermen in reincarnation, an artificial selection mechanism was launched that saved the heikegani from extinction.

The shrimp wants to live too!

For some reason anyone in parallel, having received the status of yummy, is tied to culinary features: weight, amount of protein in milligrams, benefits for the body.

Even a child knows that the tiger shrimp is the largest. But how big is it? The length of the female reaches 36 centimeters, and the weight is 650 grams. Among tiger species there are also kilogram specimens.

Some of these crustaceans can kill fish using sound. These are called shooting shrimp and have a device on their claw that can produce a loud click that is lethal to fish swimming nearby.

The shrimp also hunts, also defends itself and really does not want to end its life as a snack.

I am a star!

The most beautiful sea creatures are stars. Anyone who has seen the bottom covered with these bright creatures claims that all the most interesting facts about marine life simply fade before this amazing sight.

For his sake, divers dive underwater with cameras to show the world the real stars of the deep sea.

We can safely state the uniqueness of starfish: they are not fish, since they cannot swim, but move along horizontal and vertical planes with the help of tenacious suction cups.

They are varied in color and shape, but they all have the same “shape” - in the form of a five-pointed star. But five rays are not the limit. Maximum - 50.

The star is the only sea creature whose limbs are called hands. It reproduces in two ways: by throwing eggs and sperm into the water or by dividing one individual into parts.

Where do “coral beads” live?

Like all other types of marine life, corals have their own “zest”, which is interesting not only to researchers of the seas and oceans, but also to researchers of fashion boutiques.

Corals are thermophilic, so an almost continuous line of reefs is located along the equator along almost the entire circumference of the planet.

Sea monsters. Interesting names of sea creatures

The sea kindly provides people with various types of marine life for observation and study. But among them there are some that are downright scary and unpleasant to study.

Sea devils, or anglerfish, are recognized as the ugliest inhabitants of the ocean depths. They live at the greatest depths, as if hiding from prying eyes and realizing their unattractiveness.

The viper fish is also disgusting; before the meal it looks like a standard snake, and after it looks like an inflated balloon.

Fearsome creatures include dragonfish, saberfish, largemouth and Atlantic giant squid.

Interesting fact about sea life - Horror stories have been around since World War II, when surviving sailors from sunken ships spoke in horror about a huge monster that dragged their comrades to the depths.

They really look like people from and live in the darkest corners of the ocean, so meeting such “fish” is very rare, although you need to know about their existence. Just in case.

The depths of the sea are full of amazing secrets and they are inhabited by no less amazing living creatures, which will be discussed today. The largest animal on the planet that lives in the ocean is the whale. Despite the fact that he himself is huge, his throat is very small, and his mouth is blocked by horny plates with fringe along the edges, which is also called whalebone. This whalebone is intended for straining food. And the whale feeds like this: taking sea water into its mouth, it filters it through the whalebone, as if through a huge sieve.

The water is filtered and poured out, and small animals - crustaceans and fish - remain inside the throat. And although they are not fish, they are large sea animals. Female whales feed their little cubs with milk and whales breathe air, like earthly animals.

And there are also toothed whales, which... They do not have whalebone, but they do have huge and sharp teeth in their mouths. The sperm whale will dive deep into the sea and grab a squid with these teeth.

Octopuses are very strange animals. They are called cephalopods because their legs grow straight from their heads. Although these legs are more like tentacle arms with powerful suction cups with which it grabs prey. The octopus has eight such tentacles. If it touches the fish with its suction cups, it will stick tightly to the tentacle. The octopus can move very quickly, since it has its own natural jet engine. The octopus will take water into its water bag and push it out with tremendous force, moving in the opposite direction.

The swordfish gets its name from its sharp, bony nose that actually resembles a sword. The swordfish quickly bursts into the very thick of the school of fish and begins to strike prey left and right with its swordtail. The blow of her sword is so strong that it can pierce a fishing boat.

All sorts of animals live in the sea-ocean. There are even sea horses. The seahorse constantly blends in with its environment so that it cannot be detected.

And the sea rooster, despite its name, does not know how to crow, it only cracks loudly, as if. But it is painted so brightly that it will give odds to any earthly rooster.

We only met a small number of amazing fish living in the depths of the ocean. In fact, the variety of living things in the ocean is as huge as the ocean itself. And ocean scientists are still discovering more and more new species of marine life.
