The old turtles in the ocean are natural enemies of jellyfish, and the turtles here refer to non-herbivorous turtles. They have no teeth, but they have eagle-sharp mouths that can grind jellyfish. The tentacles of the jellyfish under the umbrella are its digestive organs and its weapons. The tentacles are covered with stinging cells, which can shoot venom like poisonous silk.

Turtles, on the other hand, start from the jellyfish's head, cleverly avoiding poisonous tentacles to avoid being stabbed. Moreover, the turtle's skin is particularly thick and is not easy to be penetrated by jellyfish stinging cells. In addition, the turtle's own detoxification ability is also particularly strong. To sum up, turtles are simply the bane of jellyfish.

Life habits of jellyfish

All jellyfish are carnivores. They feed on fish and plankton. When hunting, jellyfish are passive and only prey on animals that swim towards them. They use stinging cells on their antennae to sting or kill their prey, and then send food to their mouths and digestive cavities. Most jellyfish are almost transparent, and it is difficult for enemies to find them. Some jellyfish glow and attract prey through the faint light from their bodies.

Most jellyfish can only live for a few weeks, and some can live for about a year. Some deep-sea jellyfish can live longer. In the sea area from Malaysia to Australia, there are two kinds of jellyfish, which are called hand-dragging jellyfish and box jellyfish, and their secretions are very toxic. If they sting, they will die in a few minutes, so they are also called killer jellyfish.
