They can be found from North to South America, Africa to Asia, and all across Europe
Otters have long, slim bodies and relatively short limbs. Most have sharp claws on their feet and all except the sea otter have long, muscular tails
Almost all otters have webbed feet, some more webbed than others, and they can close off their ears and nose as they swim underwater.
Otters make a variety of different vocalizations – they include a high-pitched whistle between a mother and her cubs, twittering noises produced during play-fighting, and cat-like noises when fighting.
Otter species except the sea otter live in dens, mostly made by other animals, such as beavers. They can also live on rocks or driftwood.
Otters are playful, intelligent and inquisitive animals who are often seen enjoying themselves sliding around on muddy banks or in the snow.
They eat fish, clams, lobsters and small animals occurring along the shore
Different species vary in their social structure, with some being largely solitary, while others live in groups – in a few species these groups may be fairly large.
