Whether they’re completely tied to a body of water or only swim occasionally, aquatic mammals are a wide and diverse group living all over the world. You might recognize a beaver as an aquatic mammal but, unfortunately, mistake a humpback whale as some kind of fish. You’d be wrong about the humpback whale, of course. From dolphins to moose, aquatic mammals play a huge part in their own ecosystem, are highly intelligent, and are very strong swimmers. So, what other mammalian swimmers are among us? Here are 25 Amazing Aquatic Mammals You Have To See.

Amazon River Dolphin
Also known as the Pink Dolphin, the Amazon River Dolphin is only found in freshwater of the Amazon and Orinoco river basins. It’s a relatively abundant species but is currently considered vulnerable due to man-made dams.
The Ladoga Seal, also called the Ringed Seal, is the most common and smallest seal in the Arctic.
North American Beaver
A semi-aquatic rodent, the North American Beaver has transparent eyelids which help it see under water and very sharp teeth to chew wood and build its dams. They play an important part in the environment and help it thrive.
A bizarre looking aquatic mammal, the Amazonian Manatee has two forelimbs but no hind limbs. It’s the smallest of the Manatee species.
The Eurasian Otter lives in freshwater habitats in Europe. Fish, frogs, and even birds are all part of their diet.
