Are jellyfish poisonous?

Not poisonous.

It is a marine coelenterate. The body of the jellyfish is umbrella-shaped, translucent, white, cyan or yellowish. The diameter of the jellyfish umbrella can exceed 45 cm and the maximum size can be 1 meter. The 8 thickened carpal bases (with shoulders) under the umbrella heal and the mouth disappears (replaced by the secondary mouth of the sucker). There are many rod-shaped and filamentous tentacles in the mouth and carpus below, with dense nematocysts on them, which can secrete venom.

Its function is to release venom to paralyze small animals for food. Jellyfish are widely distributed in tropical, subtropical and temperate coastal areas. Common jellyfish in my country include edible jellyfish with smooth umbrella surface and only filaments at the mouth and wrist, or rod-shaped jellyfish with both rods, and jellyfish with many small warts on the umbrella surface. Yellow-spotted jellyfish.

The life cycle of jellyfish has gone through the main stages of fertilization, aphids, larvae, polypoid larvae, transversely split bodies, butterfly-like bodies, and adult stings. In addition to the sexual reproduction process in which sperm eggs are fertilized in the body, the polyp-shaped larvae of jellyfish will also produce creeping roots to continuously form foot capsules, and even the transverse body will continue to split into multiple disc-shaped bodies, through asexual reproduction.
