I hope you mean under water. And yes they can. Some mammals even live under water, like a dolphin, whale or seal.
Aquatic mammals are mammals that can swim and live in water if necessary.
Otters and polar bears are two mammals that swim extremely well underwater.
Yes, they are. Fish cannot be removed out of water without dieing, but mammals can be in water and land, and mammals have more organs than fish, but fish are the only ones with a Swim bladder. A Swim Bladder helps the fish find density in water to float and swim.
Otters are mammals but they can swim and live in water.
most can swim alot of mammals that can swim are dogs
Dolphins, Porpoises, Whales, Dugongs, Manatees, Hippos, Otters, Seals, Walruses are mammals that are very good at swimming. Most mammals can swim to some degree but there are some that like to swim and others that don't like to swim - like domestic cats. Domestic cats can swim, but they are very unhappy about it. Tigers, that are another cat, love being in water and swim well. Did you know that elephants can swim? They can cross lakes, rivers and sea inlets.
Humans and chimps are the only mammals that have to be taught how to swim. All other mammals are natural swimmers. Most amphibians can swim, and some reptiles, but reptiles like to be kept dry. Only some birds can swim. Pelacans, Segals, and other birds around water can sit on top of the water, but I think segals can dive under water for food.
Not all mammals can swim, and many choose not to. Cats, while known to avoid water, can be taught to swim. Mammals that are not known to swim are gorillas (although not proven unable to do so) and most armadillos (though at least one species can float and paddle). Orangutans, though instinctively not swimmers, can be taught to swim.
Whales are mammals and must breath air. If they cannot reach the surface to breath they will drown.
Most mammals are capable of swimming. The ones that spend all of their time in water are called aquatic mammals, and the ones that spend part of their time in water (such as platypuses, otters and beavers) are called semi-aquatic.
they go for a swim
a lot
