Fun River Otter Facts For Kids
Gallery
The North American river otter is one of the most interesting semi-aquatic animals out there!
It can stay underwater for up to eight minutes and, for hunting their prey they leave the water and can run up to 15 miles (24 km) on land as well. Owing to their strong teeth and thick fur, otters can also eat snakes and also the eggs of snakes, along with other injured animals, birds, and turtles.
In the water they have a few predators that pose a danger to river otters, however, on land, they are more susceptible to becoming the prey of many other animals such as foxes, bobcats, wolves, and even black bears.
The sea otter is similar to the North American river otter apart from the fact that it spends most of its life in the sea while the river otter spends it on land to search for food or in freshwater bodies.
