Sea rabbits are hermaphroditic creatures, inhabiting on the bottom of the sea, with naked bodies, and there is an egg sperm groove between male and female reproductive holes. Sea rabbits are distributed in the warm sea areas of the world, and are also produced in the warm sea areas of China. Sea rabbits are the first animals discovered by scientists that can produce plant pigment chlorophyll.

5. Blue Dragon

7. Quewei mantis shrimp

Mantis shrimp's second pair of jaws is very developed, which is a sharp weapon for it to prey and defend against the enemy. When attacking prey, it can eject the front end of the catching limb in one fiftieth of a second. A pistol bullet with a top speed of more than 50 miles per hour (about 80 kilometers) and an acceleration of more than 0.22 inch (5.588 mm) can produce an impact force of up to 60 kilograms. The high temperature caused by friction can even make the surrounding water emit electric sparks. Once a scientist was caught in the sea wearing gloves and hurt his fingers, bleeding profusely. Brought back to the laboratory and put in a measuring cylinder, the measuring cylinder was also smashed by it, which was evident in its ferocity.

10. Star-nosed mole

Star-nosed mole is the fastest mammal predator in the world. With the help of high-speed cameras, it can be seen that the "star nose" can touch more than 12 places per second. Therefore, the star-nosed mole can complete the whole process of determining the position of prey and preying on prey in a quarter of a second.
