The first to appear is the sea rabbit, also known as the sea slug. There are many kinds, one is cuter than the other. Although there is no hard shell, people are also shellfish, but the outer shell degenerates into the inner shell, which can change the color of the body and disguise it in the surrounding environment to save their lives. This ability to confuse the real with the fake is actually a small magic weapon for many marine creatures.

The second one is boxing crab, holding two clusters of small anemones in his hand, using the toxicity of small anemones to protect himself, just like enthusiastic cheerleaders. It is said that if you can't find anemones, you have to hold corals. In short, you will never go home empty-handed.

The third place is mantis shrimp Swallowtail. Although it looks good, it is actually not easy to mess with. It is known as the "Bruce Lee of the Sea", with a punching speed of 80km/h, and can be bought in the pet market now, but I advise you to keep it, and don't put other small fish and shrimps in the jar. In addition, the fish tank is best bulletproof.

The fourth kind is the stone fish, whose main living state is disguised as a stone, with a "bitter" appearance, gambling fins on the back and toxic sacs under the poisonous fins. If the diver accidentally steps on it, he can experience the feeling of "the most painful sting of human beings". If he doesn't go to the hospital in time, his life may be in danger.

The fifth appearance is a giant octopus, which can kill great white sharks. This sentence is enough to prove its ferocity, and it is also a frequent visitor to fantasy movies. It can grow up to 500 Jin at most, each sucker can absorb 15 Jin, and it can change color when encountering enemies.
