Detailed explanation-1: -Jellyfish have stinging cells called nematocysts inside of their tentacles. A single tentacle may contain thousands of nematocysts. Nematocysts contain a poisonous substance (venom) that helps jellyfish protect themselves. The venom also helps them capture food by stinging it.

Detailed explanation-2: -The jellyfish sting actually comes from tiny nematocysts, or stinging cells, on the jellyfish body. When triggered, these cells eject poison-tipped barbs that help the jellyfish catch food in the ocean. The nematocysts can still release their sting even after the jellyfish is dead.

Detailed explanation-3: -Because jellyfish are slow-moving, weak animals, they use stinging tentacles to capture and immobilize their prey. These tentacles are covered with stinging cells called nematocysts that each discharge a tiny, harpoon-like structure that carries venom.

Detailed explanation-4: -Jellyfish sting their prey with their tentacles, releasing a venom that paralyzes their targets.

Detailed explanation-5: -Most jellyfish are “passive” feeders. This means that they float through the water eating whatever they happen to pass in the water and can fit in their mouths; anything from tiny shrimp and krill to small fish.
