What type of cnidarian cell is like a tiny harpoon?

The type of cnidarian cell that resembles a tiny harpoon is called a cnidocyte. Cnidocytes contain specialized organelles known as nematocysts, which can be triggered to eject a coiled, barbed structure for capturing prey or defense. When activated, the nematocyst rapidly unfurls and can inject toxins into the target, effectively immobilizing it. This unique adaptation is essential for the survival of many cnidarians, including jellyfish, sea anemones, and corals.
