Otters are semi‑aquatic carnivorous mammals in the weasel family, known for their long, slim bodies, webbed feet, dense waterproof fur, and playful behavior in water.

Quick Scoop: What Is An Otter?

Otters belong to the subfamily Lutrinae within the weasel family Mustelidae, which also includes animals like weasels, badgers, and wolverines. There are around a dozen living otter species worldwide, and together they range from small river otters to the much larger sea and giant otters.

Physically, otters have streamlined bodies, relatively short legs, and powerful webbed feet that make them strong swimmers. Their thick, insulating underfur is covered by longer guard hairs that trap a layer of air, helping keep them warm, dry, and a bit buoyant in cold water. Most species have long, muscular tails that work like a rudder, helping them turn and propel themselves as they swim.

In terms of lifestyle, otters are active hunters that mainly eat fish but can also take frogs, crabs, shellfish, and sometimes birds or small mammals, depending on the species and habitat. Many species live along rivers and lakes and enter the water to hunt or travel, while sea otters spend most of their lives in the ocean. They are widely noted for their playful behavior, including sliding into water and playing with objects such as stones.

Socially and behaviorally, otters often live in family groups, and in some species the young stay with parents for many months as they learn to hunt and swim. They can live for many years in the wild, and in several regions some otter populations have declined because of habitat loss, pollution, and hunting, prompting conservation efforts.

In short, when people ask “what is an otter,” they usually mean this sleek, playful mammal of rivers, lakes, and coasts, superbly adapted to life in and around the water.
