Seals are nice cute creatures they have a big nose.Seals are related to walreses and sea lions.There are 33 speacies like harp seals,harbor seals,gray seals,weddelle seals,northen seals,leopard seals and many more.Seals use there side to steer under and on the water.Seals look weird on land but under water seals are cute and cuddly thats my opinon.Seals torpedo shape allows seals to swim quickly and efficiently.Seals the shape also helps them escape their emimies such as sharks and catch their prey such as fish. Seals move so efficiently in the water that they can travel far from land to find food without using a large amount of energy.The largest seal is the elephant seal. An elephant seal can weigh more than 2220 kiograms, which is about the weight of a minivan. The smallest seal is the ringed seal, which only weighs 50 kilograms, about the same as a big dog.A harbor seal can weigh between 70 and 120 kilograms about the same as an adult human.After the pup is born, it learns to find its mother by smell and call. But before the baby seal could find food on its own the mother or father seal abandon the baby seal and goes back to the sea.Harbor seals and their Some seals can stay underwater for over an hour. Harbor seals can dive to more than 500 meter below the surface of the ocean. They’re able to do this because seals have enveloped ways to conserve oxygen.Seals aee conervoerse S eals are prey for other predators such as sharks and orca whales. However, human beings are a greater threat to seal populationsthan any natural predator. Humans hunt seals for their oil, pelts, and meat. In some places harbor seals are also killed because they’re blamed for decreases in the fish population. However, this may not be the case. overfishing ocean poullution, and destruction of fish habitat may be causing these decreases. O ne species of monk seal, the Caribbean monk seal, has been hunted to extiction The Hawaiian monk seal is endangerd and the Mediterranean monk seal is considered critically endangered because of human disturbances at breeding grounds. Not all these disturbances are on purpose. Often monk seal cows beach themselves to give birth. Tourists who don’t realize what’s happening think the cow has become stranded on the beach. They may chase the cow back into the water, thinking they’re saving her life. However, this may actually kill both the cow and her pup. Over time, monk seals have moved to more isolated locations, but there are few safe places left. Some scientists believe climate change may also be affecting seals by causing changes in the populations of animals seals eat as well as melting the cold, icy habitat where some species live.Seals S eals can live in oceans as well as freshwater lakes, such as Lake Baikal in Russia. However, most seals live in and around Antarctica and the Arctic Circle. Antarctica is so cold that it has no permanent land mammals, but six
