Coelenterates are relatively inferior organisms, and some of their characteristics are more prominent. For example, coelenterates are generally radially symmetrical, which means that their bodies can be divided into two symmetrical parts by the central axis. For example, their body structure includes many different cells, and there is also the phenomenon of tissue differentiation. Also, they may have a nervous system and so on. Jellyfish belong to coelenterates, and their characteristics conform to the outstanding characteristics of coelenterates, such as their body symmetry, for example, they have a nervous system, but no brain and so on.
Jellyfish are relatively inferior creatures. Their physical structure is relatively simple, and their IQ is relatively low. However, they also have some effective means to protect themselves. For example, jellyfish have many tentacles with special structures that release venom, which can paralyze their enemies. When they feel their lives are threatened, they will release toxins to the enemy, while the enemy is paralyzed when the rapid escape.
However, not all jellyfish are equally toxic, different species of jellyfish toxicity is strong or weak. Some jellyfish toxins are also harmful to the human body, because they act on the heart and may stop the heart in an instant. We often encounter some jellyfish which look better and have a gentle personality, but we need to pay special attention to the toxicity of this jellyfish, so we must stay away from them.
