There are all kinds of lovely creatures in the ocean. Many people like starfish. The starfish is purple on one side and orange on the other side. Can create such a beautiful creature.

The starfish's trick is that it has the ability to clone itself. If a starfish is torn into several pieces and thrown into the sea, each fragment will quickly regenerate the lost part, thus growing into several complete new starfish. For example, the sand starfish can grow a complete new starfish with a wrist that is one centimeter long, while some starfish are even more capable, and a complete new starfish can grow as long as they have a stump of the arm. The starfish's wrists and body discs can regenerate naturally after being damaged or self-cutting. Any part of a starfish can regenerate a new starfish. 

Because the starfish has such amazing regeneration ability, it is a trivial matter for it to lose an arm and a limb. It is known that scientists are exploring the mysteries of starfish's regeneration ability in order to gain inspiration from it and seek a new medical method for mankind. Scientists have found that when a starfish is injured, backup cells are activated. These cells contain all the genes of the lost part of the body and cooperate with other tissues to regenerate the lost wrist or other parts.

In addition to starfish, jellyfish are also very cute sea creatures. The main component of the jellyfish body is water, and its body water content is generally more than 95%. It is composed of inner and outer germ layers. There is a very thick mesogel layer between the two layers, which is not only transparent, but also has a floating effect. . When they are moving, they use the water spray reflex in their bodies to move forward, just like a round umbrella floating rapidly in the water.

The jellyfish has a special gland in its umbrella that emits carbon monoxide to swell the umbrella. When the jellyfish encounters an enemy or encounters a major storm, it will automatically release its gas and sink to the bottom of the sea. After the sea is calm, it only takes a few minutes to produce gas to inflate itself and float. There is a small ball on the thin handle in the middle of the tentacles of the jellyfish, which has a small listening stone, which is the "ear" of the jellyfish.
