We may have seen news of jellyfish hurting people in peacetime. They may paralyze humans and even cause human death in a short period of time. But they don't hurt people because they have electricity. Jellyfish have a nervous system, their nerve signals can be transmitted by relatively weak radio waves, but this weak radio wave is only transmitted in the jellyfish body, they will not discharge to the outside world.
When jellyfish harm humans, they actually rely on their toxicity. Jellyfish usually have tentacles in their body structure, which are not only their digestive organs, but also their weapons to attack their enemies. These tentacles have many stinging cells on them, which can release poisonous liquid, which can paralyze the enemy. Jellyfish have similar effects on humans, and these venoms may also have a paralyzing effect on humans. Especially noteworthy is that some jellyfish are very toxic, their poison may directly affect the human heart and respiratory system, may lead to human death in a short time because of breathing difficulties, heart failure. Especially those jellyfish that look more beautiful, they may be more toxic.
Jellyfish is a relatively good-looking creature, not only their own color is good-looking, but also some will shine. Many organisms that emit light have luciferin or luciferase, which emits light under the action of oxygen. But jellyfish are different, most of their bodies are water, and there is no similar material. After many experiments, researchers have found that jellyfish actually rely on a substance called "equilin", which is a special protein, the more this substance, the more light the jellyfish emit. The researchers also isolated a chromophore from the substance.
