What is a stinging cell cnidarian called?
A cnidocyte, cnidoblast, or nematocyte is a type of venomous cell unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.). The cnidocyte cell provides a means for them to catch prey and defend themselves from predators. A cnidocyte fires a structure that contains the toxin, from a characteristic sub-cellular organelle called a cnidocyst (also known as a cnida or nematocyst). This is responsible for the stings delivered by jellyfish.

What are sea anemones stinging cells used for?
Cnidarians (Phylum Cnidaria; stinging animals, including sea anemones) use their stinging cells (properly called cnidocytes, Latin for "stinging chamber") in order to capture prey. The cnidocytes are basically a cellular-sized harpoon. When prey bumps into the cnidocyte, a trigger mechanism is activated and the harpoon rushes out. Some species add poisons for good measure. The tentacles are then able to draw food to the mouth, where it is digested and the waste expelled through the mouth (yes, they use their mouth as an anus).
