Sea otter is one of the smallest sea animals. The male sea otter only has a body of 1.47 meters and weighs about 45 kilograms, similar to a dog. Female sea otters are about 1.39 meters long and weigh 33 kilograms. Its little head, its little ears. With a naked snout, a bearded upper lip, and a fat, rounded body that resembles a weasel, experts put it in the carnivora family. Its forelimbs are bare and curved, and its tail is flat and long, accounting for about 1/4 of its body length. The hind limbs are flat and broad and look like fish fins on the outside, but inside they have no fin structure and are made of phalanges. Sea otters also have five toes, the longest of which is the first. The bones are covered with skin, making for incomparable paddles. When they swim through the water, their streamlined bodies rise and fall like fish, their bodies are very soft, and at the same time they swap their hind limbs for strokes. Their flat tail trailing behind acts as OARS and rudder at any time, so they are very flexible to turn and navigate the waves. Sea otters are not only expert divers and swimmers, but also excellent divers. They often climb to the rocks on the shore and jump into the sea. Then it glides into the water in a spiral, with hardly any water flying. If any country's divers reach this level, it will certainly get a full mark.
