Ctenophores lack stinging cells while Cnidarians possess stinging cells .
Cnidarians are members of the phylum Cnidaria. They are a diverse group of animals that includes jellyfish, corals, and sea anemones. Cnidarians are characterized by their radial symmetry, specialized stinging cells called cnidocytes, and a basic body plan with a central mouth surrounded by tentacles.
The Phylum Cnidaria includes bluebottle jellyfish, anemones, corals and other jellyfish (except comb jellies). There are several Classes: Hydrozoa (Anemones, Corals), Scyphozoa (Jellyfish) and Cubozoa (box jellies). Cnidarians have two distinct body forms: polyps and medusae. Polyps have a tubular body attached to the substrate, or to each other in a colony (e.g. coral). Medusae are free swimming (e.g. adult jellyfish). The most important feature of Cnidarians is their stinging cells (nematocysts). These are in the tentacles and the body wall. Each stinging cell contains a coiled thread that, when pressure is applied, is ejected from the cell. These stinging cells can be used for defense or to capture prey. Some stinging cell threads have barbed ends and are connected to poison sacs, making them particularly nasty! hope that helps
cnidaria
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.
The entire cell is a cnidoblast and it contains a stinging 'barb' called a nematocyst.

No, most cnidarians have stinging cells, not sponges.
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.

cnidarians
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.

I think it's called cnidarians
Cnidarians all have stinging cells called nematocysts with which to catch their prey.
The stinging cells in a jellyfish are located in it's tentacles.
