The otter's habits:

The otter hides in the hole during the day to rest, and comes out at night, usually live alone.

The otter is skillful in water, good at swimming and diving, soft body and long tail can reduce the resistance of movement in the water, swim into the front limbs close to the body, with the hind limbs and the tail to hit the water to push, but also plays the role of the rudder, so that the body for the undulation of the waves, posture is very much like an eel.

The otter is not good at walking on land, mainly with the abdomen against the ground creeping, sliding, rolling and intermittent jumping step, as well as waddling in thin ice or shallow snow roaming, encountering enemies immediately drilled into the ice cave or under the snow to escape.

The otter does not linger for a moment when it encounters light like other nocturnal animals, but looks back while fleeing, showing a peculiar appearance. Otters live in dens, but generally do not have fixed dens. The mother settles down when she is nursing her cubs. Nests are located in the rocky crevices of the embankment or under the roots of trees, dug by themselves or utilizing the old nests of foxes, badgers, and hares, and repairing them.

The otter's food is mainly fish, often will catch the fish out of the water and eat, but also catch small birds, small animals, frogs, shrimp, crabs and crustaceans, and sometimes eat part of the plant food.

The otter likes to dive into the water from the shore or river cliffs to chase fish, but the most commonly used hunting method is ambush, especially in winter, often hiding in ice holes, waiting for the fish to swim over to suddenly rush out to feed. When the waterfowl are found to be swimming slowly on the surface of the water, they will also sneak closer from underwater, and then take a bite of their prey, and then slowly eat it.
