The Atlantic Ocean is the second largest in the world. It accounts for about 29% of the total area of the oceans, and its waters are washed by the shores of South and North America, Europe and Africa. The flora and fauna of the Atlantic are represented by a wide variety of aquatic plants and marine animals (both vertebrates and invertebrates). Here are the main animals of the Atlantic Ocean, which are found in its vast expanses.
The habitat of the Atlantic walrus in the expanses of the Atlantic is located between the Canadian Arctic in the east and the Russian – in the west. In this region, there are about 25 thousand walruses, but the number of adult individuals is constantly decreasing.
These marine animals of the Atlantic Ocean have characteristic elongated fangs that resemble tusks. They usually live in colonies, and with the help of a roar of different tonality they communicate with their relatives in a group. Atlantic walruses feed on small invertebrates. Their life expectancy is 30-40 years.
This type of dolphin is found in various subtropical and tropical marine regions around the world. They are well-known for demonstrating funny tricks when jumping out of the water. Before diving back into the water, these dolphins perform several somersaults in the air. To communicate with representatives of their kind, they use various whistles.
The long-nosed dolphin has teeth, but it does not chew on food by them. These marine animals are very sensitive to the frequency of the sound and use echolocation to study their surroundings and while hunting for prey. They feed on fish, squids and crustaceans.
These animals that inhabit the waters of the Atlantic Ocean, better known as sea cows. They are found only in warm waters. Manatees – mostly herbivores. The main food is grass and plants growing on the seabed.
These are large mammals that can grow up to 4 meters and weigh about 590 kg. Their distinctive feature is the presence of flippers that resemble oars. West Indian species are mainly found in the Caribbean and the Gulf of Mexico (particularly in Florida), and West African species inhabit waters in the region of West Africa.
This representative of the Atlantic Ocean fauna belongs to the class of cartilage fish. It is found in the waters of the Caribbean and the Gulf of Mexico. The spotted eagle has a longer tail than most skates, and its muzzle is shaped like a duck’s head.
He hunts for crustaceans and various small fish, often digging his head in search of prey among the sand on the seabed. Although these stingrays are considered underwater animals, sometimes they can be seen jumping out of the water. The population of these skates is endangered due to the frequent attack of sharks on them.
This fish is on the verge of extinction due to over-fishing. Due to the metallic blue color, it almost merges with the ocean waters, and the drop-shaped body allows it to develop greater speed.
Tuna hunts for herring, gray mullet, mackerel, squids, crabs and shrimps. This marine fish is also known for its annual migration through the waters of the Atlantic. The largest tuna that was caught in the vast Atlantic Ocean weighed 679 kg.
Great White Shark
These representatives of cartilage fish are endothermic. In addition to the five standard senses, they possess electromagnetism. In the mouth of the white shark three hundred triangular-shaped teeth, arranged in 3 rows. They tear their prey to pieces.
The white shark is the largest ocean predator. She can even hunt other species of her relatives, as well as sea lions, seals and turtles, does not shrink from carrion and fish. These sharks live up to 60 years old, growing to 6 meters and a length and reaching a weight of more than 2.2 kg. Their largest population is found near Gyer Island in South Africa.
Atlantic green turtle
The name of these marine reptiles is associated with the accumulation of green fat under the smooth shell. Their color can vary in different shades of yellow, green, gray, black and brown. Among all its marine relatives, the green turtle has the largest shell and can sometimes change its color.
Although these reptiles are primarily herbivores, they can also hunt jellyfish and other small marine life. On average, a green turtle grows in length to 1.5 m and weighs from 68 to 190 kg.
Leatherback Sea Turtle
It is found in the southwestern, southeastern, and northwestern part of the Atlantic Ocean. Often it lives and hunts at a depth of 1280 meters. The leatherback turtle is more overall and has larger front paws than representatives of other species. But her shell is soft and flexible.
It occurs in colder waters than the green turtle, and is carnivorous. The leatherback turtle hunts mainly on jellyfish, crustaceans and small fish. By producing offspring, does not care about him at all.
The name of this marine mammal is due to the presence of a dorsal fin resembling a hump. These whales travel enormous distances during migration associated with the mating season and the reproduction of offspring.
They feed on fish, plankton and krill, consuming up to 1360 kg of food per day. These giants weigh from 22 to 36 tons, growing to 18 meters in length. The body of a streamlined shape is longer in them than in other whales, and the abdominal fins are much longer.
Animals usually have paired tusks, but in some cases they can grow together into a single one, as is the case with narwhal. It has no dorsal fins, but there are pectoral fins. On average, these animals can weigh from 800 to 1600 kg with a body length of 3.95 to 5.5 m. The canine serves as an organ of smell and as a means for echolocation.
It feeds on the Arctic and polar narwhal species of cod and halibut, as well as shrimp and squid, which are found on the seashore of Greenland. They themselves are threatened by walruses, polar bears, orcas and people.
The largest animal of the dolphin family is often called the killer whale. The killer whale hunts for almost everyone, including seabirds and mammals, seals and sea lions, fish and squid.
There is simply no other predator of this kind in nature. Adults can reach 9 m in length and weigh an average of 3,600 to 5,000 kg.
This sea animal is a bone fish and the closest relative of tuna and salmon. It has thin skin instead of scales and needle-like thorns along the edge of the whole body. Seahorses do not have teeth, so they feed, sucking prey with their elongated jaw immediately into the stomach.
Their main food is plankton and some species of crustaceans. While waiting for prey, these fish can be masked against the background of underwater vegetation, changing their color in accordance with the environment. Their reproduction is also very specific, since the male generates offspring to the light.
Mediterranean monk seal
This animal of the Atlantic Ocean is found in the region of Cape Blanco and Madeira Island and is the rarest of all pinnipeds. According to statistics, in the world there are less than 700 individuals.
This seal has a small flat and wide muzzle and short flippers with small thin claws. The body is covered with a short hairline, which is updated every 6-8 weeks. These seals feed on various fish, squid, eels and octopuses. The maximum duration of their life is 45 years.
The second largest species of penguin is found in the southern Atlantic Ocean. Growth of this bird can reach 1 meter, and weight – from 9.3 to 18 kg. It feeds mainly on fish, less often on squid.
King penguin can dive to a depth of 100 to 300 meters below sea level for the extraction of food and be under water for up to 5 minutes without lifting to the surface. Like other penguins, it is a flightless bird that walks or slides on the ice.
This species is found in shallow water near the coast. The species name is associated with the color of the body, which can vary from yellow-brown to olive-green.
The muzzle of the lemon shark is short, round in shape. She has poor eyesight, but an excellent sense of smell. It is a nocturnal predator that finds potential prey using the organs of smell and the electroreceptor system. It feeds on fish, seabirds, small sharks, crustaceans and mollusks. It can grow up to 2.5-3 meters and weigh up to 250 kg.
