The North American River Otter, known in North America as the
Common Otter, is one of the largest otters, growing up to
1.5 metres long. It lives in rivers, inland waterways and
some coastal stretches of USA and Canada. It is at home on
land or water, living in burrows on banks.
The shape is aerodynamic with short ears low on the head and with webbed feet for swimming. As elsewhere, numbers have
declined substantially as a result of human activity, especially river pollution.
