Jellyfish have cells called cnidocytes, which contain nematocysts, and located on their tentacles and on their manubrium. Whenever a predator comes in contact with cnidocytes, hundreds to thousands of cnidae (filaments of the nematocysts) are ejected in the predator's direction. Nematocysts' cnidae inoculate a poisonous or allergenic mixture into the predator's body.

As to the functions: stinging nematocysts function primarily for the capture of prey, and secondarily as a defense mechanism. There are many types of nematocysts, such as those that function to inject toxins to immobilize prey, and those which serve to entangle and hold onto the intended meal by wrapping around it. Species of cnidarian jellies vary in the types of nematocysts they possess, and this can be used to some extent in classifying and identification.
