The North American river otter (Lontra canadensis) is a semiaquatic mammal that lives along its waterways and coasts. It is the only river otter that is found north of Mexico. These animals live in burrows and like most predators, prey upon the most readily accessible species. They suffer greatly from habitat loss and are often captured for their fur. In the wild, they live only for 8-13 years but in captivity, their life expectancy can reach up to 25 years.
