River Otter

A river otter is a semi-aquatic mammal found in and around rivers and coastal areas throughout North America. They are known for their playful nature, sleek bodies, and incredible swimming ability.

River otters have a long, slender body with a thick neck and a broad head. Their fur is a dense, water-repellent brown or grayish color, which provides insulation in the water. They have webbed feet and a powerful, tapered tail that they use for propulsion and steering while swimming. They are very agile on land, but they are most at home in the water.

River otters are found in a variety of freshwater and coastal marine habitats, including rivers, lakes, streams, estuaries, and marshes. They are highly territorial and live in dens, called holts, which are often found in abandoned burrows of other animals. They are carnivores, with a diet that consists mainly of fish, crayfish, crabs, and other small aquatic animals.

River otters are known for their playful and social nature. They often live in family groups and can be seen sliding down muddy or snowy banks into the water, a behavior that is believed to be both for fun and to mark their territory. They are excellent swimmers and divers, capable of staying underwater for several minutes and closing their nostrils and ears to prevent water from entering.
