Fur seal, also known as fur sea lion, fur seal or eared seal, belongs to the family Furseals of the order Carnivora (although the order Pinpoda is sometimes listed separately as Pinpoda). Pinniped comes from Latin, which means "with feet like fins". There are about 20 million pteropods in the world. Sea lion refers to a finfoot with an external ear, and there are thirteen species in total, including five species of sea lions, eight species of northern fur seal/kloc-0 and eight species of southern fur seal. And those pteropods with inner ears are called true seal, that is, the family Phocidae. Seals are all over the world. In addition to northern fur seals living in the Bering Sea, fur seals are also found in the waters of Australia, New Zealand, Tasmania, South Africa and Antarctica. Male adult fur seals are about 7 feet long and weigh 600 pounds. The female is about 5 feet long and weighs 300 pounds. The pups weigh about 10 pounds at birth and about 30 to 35 pounds when they are 4 months old. The difference between male seals and female seals is that the female fur is lighter and the male neck hair is thicker. The fur of newborn seals is black and will turn to the same gray-brown color as that of adult seals within one year. Its teeth are small, and they will continue to grow only after continuous and stable rearing-that is, whenever the rearing of newborn seals is stopped, their teeth will stop growing. The fur seal is warm-blooded animals. However, due to the cold climate in the polar regions, fur seals must be kept warm by their thick fur (once a year) and a layer of subcutaneous fat of about 6 inches. Seals also have long and sensitive beards to sense whether there are food or natural enemies around them. Another feature of fur seals is their flippers, which makes them fast and elegant swimmers. The flippers of adult fur seals are about 1.5 feet long and about 6 inches wide. Seals have keen vision and hearing, but poor sense of smell. This may be because the cold climate in his place of residence limits the spread of odor, which leads to the deterioration of his sense of smell. Living environment Northern fur seals live in the northern Pacific Ocean. They swim south to the central coast of California every year and then return to the North Pacific. This migration process takes eight months, and they always keep a distance of at least 10 miles from the coast, and never go ashore. No one knows why. During the non-migration period, northern fur seals generally inhabit the Pribil of Biloff Islands and Commanders' Islands between Alaska and Siberia. Walrus, whale, narwal, polar bear, octopus, squid, other kinds of pteropods, and a wide variety of birds and fish also live in this area. Among them, some are natural enemies of fur seals, such as shark, polar bears and Killer Whales, which all feed on fur seals. However, the biggest predator of pteropods is human beings. People hunt them for their fur, meat, or grease, even though it is against the law in most areas. Active fur seals are born with the ability to move forward and swim on land. They are very good at swimming. Soon after they are born, they can swim for 5 minutes at a speed of 15 miles per hour and dive to 240 feet underwater. Seals are clumsy on land, but not as clumsy as real seals. The reason is that the flippers of the former are bigger, so the fastest speed can reach 5 miles per hour. Seals are gregarious animals, and they also migrate in groups. Northern fur seals spend eight months a year migrating between the Bering Sea and the central coast of California, and never land. The remaining four months are spent mating, breeding and raising offspring. Breeding Every spring, fur seals come to rookery on the beach or island to mate and give birth. The colony of northern fur seals is generally in Puli Biloff Islands or Commander Islands. Interestingly, every seal will return to the island where he was born to find a mate. They find the right island through the position of the sun and the smell of seawater. Male fur seals usually arrive in the colony at the end of May. They will roar for territory and then fight. If the roar doesn't drive each other away, they will attack each other and have a big fight, but most of them won't fight to death. After the territorial dispute subsided, the female fur seal arrived at the colony, which was about the beginning of July. When they go ashore, they will join the harem of a male seal. There are as few as 3 females and as many as 40 females in this group. After mating, females will give birth in the second year. Female fur seals begin to have reproductive ability at the age of 5, and usually give birth every year until they are 25-but their life span may be more than 40 years. The gestation period of fur seal is 12 months, but the embryo does not develop in the first 5 months after fertilization. This ensures that pups can be born in colonies, not in the sea. Usually, female sea dogs give birth to one litter per litter, but occasionally one litter gives birth to two litters. After the cubs are born, their fur is black at first. After taking care of them for a day or two, their mother must go hunting in the sea to recover her strength. Later, the mother seal will come back to take care of the cubs for many days, and then go to the sea to hunt again. This pattern will last for 4 to 6 weeks. Female fur seals distinguish their cubs by smell and cry, and return to them. Every year, about half of the pups die shortly after birth. Some were trampled to death by other seals in the colony, while others died of hookworm or other infections. Sea dogs are carnivores. Their food sources are very extensive, but mainly fish and squid. When hunting fish, seals will dive into the water, quietly follow the prey and then bite the prey. Seals can't chew, so they either swallow food directly or tear it into small pieces and swallow it. Seals usually prey in the evening, which makes them avoid their natural enemies (sharks, whales, polar bears, etc.) to some extent. The latter rarely appeared during this period; And at this time, the light is dim, and the seal is not easy to be found. The ancestors of fur seals were terrestrial animals, and they breathed with their lungs. This means that when fur seals swim in the water under the ice, they must ensure that there are many holes in the ice for breathing. At the end of Oligocene epoch, about 30 million years ago, pteropods (including fur seals, of course) evolved from bear carnivores. At that time, along the continental coast of Europe and North America, some low-temperature currents with high nutrient content rose, which provided them with new and rich food sources-which obviously became the reason why pteropods entered the ocean. According to some theories, sea lions (including sea lions and seals) and seals (real seals) diverge from the same ancestor in the early Miocene epoch about 25 million years ago. Other theories believe that the origin of seal animals was about 20 million years ago, and it has nothing to do with sea lions.

Sea dogs are marine creatures. They belong to Pinnipeds, with streamlined bodies suitable for underwater activities, and their legs turn into fins. They are carnivores like dogs, cats and bears, but the biggest difference between them and other carnivores is that pinnipeds spend most of their time in water, and only return to land when they rest and mate. Even so, some species even mate in water. The ancestor of Pinpoda was originally a mammal that lived on land in its previous life for tens of millions of years. Seals belong to the family Sea Lions, with 7 genera and 14 species. The difference between them and seals is that sea lions and seals can walk on land because their flippers can face forward, but seals can't. In addition, ears like little fingers are also a feature that seals have long lacked. Because the male neck is densely covered with beautiful manes, it is named "Sea Lions". Sea lions are easy to get close to humans, have a good memory, and can be raised and learned. Sea lion's hair is thick, hard and fluffy, which can prevent moisture. Fur can only be used as waterproof equipment, and it has no value. A sea dog is very similar to a sea lion, with a fluffy body and a short face. Unlike sea lions, sea dogs can't learn skills. However, because of their soft and beautiful fur, hunters often kill them to get huge profits. At present, under the protection of strict international laws, the number of ethnic groups is gradually recovering.

A animal. It is a mammal. It can swim. It always eat some *** all animal.
