In addition, there are many tentacles floating in the sea with the movement of jellyfish, is it just right for the "famous" rap - "egg yolk" long skirt, fluffy hair?
Seeing such a "delicious" seafood, Xiaobian's first reaction was also like many students: Can I eat it?
However, the answer may disappoint everyone, this jellyfish is highly toxic, let alone eat, even touch, may bring life danger.
Egg yolk jellyfish are a class of carnivores that feed on plankton and crustaceans floating in the seawater, and the "fluffy" tentacles are their prey tools, when touching prey, the spine cells on the harpoon-like tentacles will shoot out venom, hunt it, and then transport the food to the stomach cavity by cilia for digestion and absorption.
Not only is there a danger of severe poisoning in the body when directly touched, but every year in late summer and early autumn, when egg yolk jellyfish gather near the beach to form large groups, it will also bring greater trouble to local human travel and fishing.
Therefore, the locals used to use Greek mythology, a deadly snake-haired banshee, to refer to this cute-looking, seemingly harmless jellyfish: "Medusa".
