Fast Facts About North American River Otters: Habitat, Diet, and Conservation

DESCRIPTION

The North American River Otter (Lontra canadensis) is a semi-aquatic mammal known for its streamlined body, thick insulating pelt, and remarkable swimming ability, reaching speeds of up to 7 mph. Weighing 11-30 lbs with body lengths from 2-4 feet, these otters can thrive in various environments, from freshwaters to coastal habitats. They primarily feed on fish, crustaceans, and amphibians, using their underwater foraging skills. While historically threatened by hunting and habitat loss, conservation efforts are helping populations recover. Watch a featured video to learn more!
