What are the stinging structures on cnidarians called?
The structures are called cnidocytes. The stinging cells themselves are called nematocysts.

i think it might me a form a defence
Yes, cnidarians are animals that are jelly fish like (including jelly fish). Cnidarians have stinging cells located on there tentacle's, they explode once any thing touches it… shocking (or paralyzing) any prey that passes by it.
because they eat me
it is a nematocyst
They are called nematocytes. They are one of at least three types of cnidocytes, the very definition of the phylum. Nematocytes sting, the other two types of cnidocytes either… adhere, or gum up their prey, substrate, or that guy that wears a helmet and does super glue commercials.
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 provi…des 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.
Cnidarians use their stinging cells for capturing food and defense.
that is not right dont lie people use this for there homework
Cnidarians have simple structure; a blind ended gut, tentacles, a pharynx and several other minor organs, and gonads.

The stinging cell of a cnidarian contains a sac that houses a coiled up tube, immersed in venomous toxins. When triggered to fire by touch, chemical stimuli, and/or nerve exci…tation, a hinged lid opens, the tube rapidly shoots out of the sac by eversion (turning inside out), penetrates the skin of its victim, and introduces its venom along the entire length of the tubule. When large numbers of these stinging cells deliver a sufficient amount of venom, the prey (or predator) is paralyzed and can no longer cause damage to the fragile jellyfish. The entire evagination process only takes a millisecond or two. These stinging cells are some of the most sophisticated in the entire animal kingdom. They fire only once and then are re-adsorbed, to be eventually replaced by a brand new stinging cell. New nematocyte stinging cells (containing the nematocyst sac organelle) are created near the base of a tentacle from interstital stem cells. They migrate down the tentacle while developing the complex internal nematocyst structure, and eventually distribute themselves into a species specific pattern along the tentacle.
There are two cnidarian body shapes, the bell-shaped Medusa, whose tentacles face downward and the vase-shaped polyp, whose tentacles face upward. Cnidarians have stinging cel…ls in their tentacles known as cnidocytes. These cells include a trigger that releases a toxin-coated stinger that paralyzes any organism that has come into contact with is. Examples of a medusa include the common jellyfish, and examples of a polyp include corals and sea anemones.
Jellyfish sting their prey using nematocysts , also called cnidocysts, stingingstructures located in specialized cells called cnidocytes .
