North American river otter

At the Detroit Zoo
Females Whisker and Stormy and male Lucius can be seen showing off their aquatic skills at the Edward Mardigian Sr. River Otter Habitat. The naturalistic environment features a 5,900-gallon pool with a waterfall and waterslide, and the habitat is designed so that small children can view the otters at eye level as they swim. Whisker in particular seems to enjoy interacting with visitors through the glass. She came here in 2009 after being hand-raised by a family that found her under a house on Mercer Island, Washington. Her mate Lucius, born in 2006, came here from the Potter Park Zoo in Lansing. He is described as laidback but protective of Whisker. Stormy, born in 2001, was rescued from the bottom of a hill along Lake Michigan. After researchers searched for her den and family with no luck, Stormy arrived at the Detroit Zoo in 2002.


Description

The river otter’s fur color ranges from white to grey, brown and black. It has a long streamlined body, a thick tail that can be up to 21 inches long and short legs. The otter’s strong tail and webbed feet help propel it through the water, which makes it a great swimmer.
