Nematocyst stinging cell. Computer illustration of nematocysts on the tentacle (blue) of a cnidarian. Nematocysts,or cnidocytes,are explosive venomous cells found on Cnidaria,which includes jellyfish,sea anemones and corals. They are typically used for self-defence or to capture prey. Each cell contains a thread (cnida,coiled,red) that is fired into the skin of the prey (bottom) to administer the toxin. This thread is fired from a capsule within the nematocyte when a hair-like trigger (cnidocil,red spike) is activated by passing prey | |
