How do jellyfish sting people and fish?
Quick Answer
Their tentacles carry microscopic stinging cells that fire toxin-filled barbs when triggered.
The Full Story
Jellyfish tentacles are lined with cnidocytes, specialized cells that contain nematocysts. When these cells are touched or chemically triggered, they fire a tiny barbed thread into the target and deliver venom. The sting can immobilize prey and deter predators, though the severity varies greatly among species. Some jellyfish stings are mild, while others can be medically serious.
