Description
A cnidocyte (also known as a cnidoblast or nematocyte ) is an explosive cell containing one large secretory organelle called a cnidocyst (also known as a cnida (PL cnidae ) or nematocyst ) that can deliver a sting to other organisms. The presence of this cell defines the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.). Cnidae are used to capture prey and as a defense against predators. A cnidocyte fires a structure that contains a toxin within the cnidocyst; this is responsible for the stings delivered by a cnidarian.
*[PL]: plural form
