It is very fast and requires very little energy. In the winter the otters use sliding as a convenient method of transportation. They can run, bound, or slide on land, and are excellent at swimming and diving in the water. River otters can move just as well on land as they can in the water. They drag the small fish to the surface where they eat them, but they drag the bigger fish to the shore where they then They race after their fish or crabs and grab them with their teeth. They can stay underwater for up to four minutes and swim at speeds of about 7 mph. The river otters stay under water and hunt for their food. However, river otters have a different strategy. Sea otters (the ones from California) dive for their food (clams and muscles and such) and then bring it to the surface where they float on their back while they eat it. In certain situations they will also eat rodents or birds. They eat mostly fish, frogs, crabs, and crayfish. River otters eat about 15%- 20% of their body weight each day. The den is like a nest, lined with leaves, bark or grass. The otters will also live in rock caves, hollow logs, or riverbanks. Elevation and temperature do not bother the otters one bit.They live in a den made by other animals such as a woodchuck, fox, or muskrat. The only things that North American river otters really need to survive is access to water and a steady food supply. They live in burrows near the waters edge, or in rivers or swamps. North American river otters live only in North America. If you were to travel out to California, you would be able to see some Sea Otters. Now, if you ever encounter one, you will know a little bit about them! I hope that I have taught you a lot about mountain lions including what they eat, what to do when you encounter one, and what they look like. The mountain lion is the biggest of their sub family. The sub family Felinae is mostly made up of small cats such as the lynx, ocelot, domestic cat, fishing cat and other small species of cats. Mountain lions are classified in the sub family Felinae. In fact, mountain lions are not even classified as large cats, they are classified with all of the small cats. They can hiss, purr, growl, and even scream, but not roar, as many other large cats do. They can not roar, instead they make noises that you would commonly hear coming from your house cat. Most mountain lions are tawny colored, but the color can range from reddish, to more of a silver color. Males tend to be slightly bigger than the females. Mountain lions are fairly big, measuring between five and nine feet from tail to nose. But, if a human encounters a mountain lion, and starts waving its arms and making loud noises, the mountain lion will likely run away. It is their instinct to chase and kill things that run from them. If a human encounters a mountain lion, and starts to run away from it, it might attack. Mountain lions tend to stay out of the way of humans, it is not their instinct to hunt them.
