Real animals in reality

Sea slug, the Atlantic sea god, is a small marine mollusk, only 3-8 cm, but it is a magical creature with great wisdom in the ocean. First of all, it has a very beautiful appearance, which seems to exist only in myths (see the picture); Secondly, it has advanced defense mechanism. This animal has a silver back and a blue belly. Under normal circumstances, it almost floats on the water. In order to avoid the enemy, it adopts anti-concealment mechanism to protect itself. Take "backstroke" for example, the blue belly is on the top and the silver back is on the bottom. From top to bottom, blue and the ocean blend together. Looking from the bottom up, the back is silver and it is not easy to be found. Not only that, but it can also take the "weapons" of other creatures as its own. It feeds on other plankton, including poisonous spiny animals that are harmful to human beings, but it is not only not afraid of the spiny cells of its prey, but can even swallow these cells into its own body and eventually become its own weapon. Even more amazing, it is hermaphrodite, and once mated, both sides can lay eggs.

China water deer

China water deer, commonly known as roe deer, is the most primitive deer, native to eastern China and the Korean peninsula. Because it likes swimming very much, it is called water deer. The shape of the water deer is also very strange. It has no antlers, only a pair of exposed fangs, which are its weapons. The reproduction of water deer is similar to that of human beings, and they can mate every month, with one child pregnant for 8 months and one child. Although it was originally from China, it was finally imported from Britain. There is no doubt that China water deer originated in China. At that time, it was on the verge of extinction because of its delicious meat. 100 years later, it was finally introduced from England. The water deer introduced from Britain was introduced and propagated on 1870, and now lives in Shanghai Forest Park, belonging to the national second-class protected animals. It is not only thought-provoking, but the water deer introduced into Britain has survived to this day, while China, as a country of origin, is on the verge of extinction.

Goblin shark

Sword-kissing shark is a very rare deep-sea species, and its family history is about 65.438+0.25 billion years, so it is called "living fossil". Its shape is hard to see at a glance, with a long and flat "nose". No one understands why its nose is so long. A long nose doesn't seem to be good for hunting. Some experts speculate that it may be related to the function of detecting prey. They generally live in the deep sea of 270-960 meters, and are also found in the deep sea of 1000 meters, so they are not easy to be caught. The deep-sea creatures of the sword-kissing shark do not seem to be endangered species, and once they landed, they did not explode themselves.
