Cnidarians have specialized sells that are called cnidocytes. They use these special cells to capture prey. Cnidocytes have a special cavity in them called a cnida. Inside the cnida a coiled up tube is held. These tubes can do many different things depending on what type of cnidocyte it is held in, like release toxins, wrap around a prey item or secrete a sticky glue like substance. A lid called the operculum closes the opening of the cnida. Cnidocytes also have a modified cilium called a cnidocil. The cnidocil is like a trigger - when it is touched it forces open the operculum and releases the coiled tube held within.
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
Every jellyfish tentacle is covered with cells called cnidoblasts. These cnidoblasts cover the nematocysts that contain the stinging threads.
The structures are called cnidocytes. The stinging cells themselves are called nematocysts.

Stinging Cells
loleveryone reading this is gonna die... lol jk
cannot capture prey
All Cnidarians have tentacles with stinging cells in their tips which are used to capture and subdue prey. In fact, the phylum name "Cnidarian" literally means "stinging creature." The stinging cells are called cnidocytes and contain a structure called a nematocyst.
These are stinging cells found in cnidarian and coelenterate. Each of them bears a stinging cell organelle called nematocyst which is used in offence, defence and attachment of animal.
Cnidaria have poisonous stinging cells and soft bodies. Jellyfish is an example.
Coral is nor arthropod , sponge or echinoderm , A coral is a cnidarian also called a coelenterate because it possess cnidocytes , stinging cells , gastrovascular cavity ,tentacles which are cnidarian charters .
several capsules occur on the body surface. each is produced by special cell called cnidoblast
Cnidarian comes from the Greek/Turkish word "Cnidos" which means stinging nettle
Stinging cells will paralyze the prey of the Hydra. This makes it a lot easier for them to capture their food.
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.
Cnidiarian is the word for the phylum of jellyfish and sea anemomes. Some of the requirements to make it into the Cnidaria Phylum are possessing radial symmetry, having no nervous system or head but having a nerve net, and possessing nematocysts (which are stinging cells unique to cnidarians). Nematocysts are also called cnidea, which likely is the basis of the meaning of the name Cnidaria.
