Nematocysts are are only found in the animal phylum Cnidaria, which includes sea anemones, corals, and jellyfish.
Nematocysts are found in sea creatures, specifically jellyfish and anemones. The nematocyst is an organelle found in these creatures that enables them to fire toxins. These toxin-causing nematocysts are responsible for the stinging capabilities of jellyfish, anemones, and other cnidocytes.

Nematocysts are located within a capsule in the cell. The capsule has a lid that opens when the nematocyst is discharged.
Phylum Cnidaria
Only once. After discharge, nematocysts are absorbed by the cnidarian and new nematoblasts must be created from interstitial stem cells (often at the base of the tentacle) and while differentiating into new nematocysts they also travel down the tentacle between epithelial layers to their final destination (in species specific patterns) within the ectoderm. This is not only an amazing process, but provides an explanation for the often complex triggering mechanisms that befits this 'expensive' resource of cnidarians.

it is called Nematocysts. these stinging cells are also found in anemones. i learned this in Mr. sanders night school. aquatic science b! :)
Nematocysts.
Nematocysts are the miniscule capsules that a jellyfish's tentacles contain. They are the tiny needles that jellies use to capture and paralyze prey.
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.
Nematocysts are specific to the phylum Cnidaria, which contains sea anemones, corals, and jellyfish, along with some less well-known animals. Nematocysts are the most common form of cnidocytes, the general term for the stinging cells all cnidarians possess.
