a capsule within specialized cells ( cnidoblasts) of certain cnidarians (such as jellyfish) containing a barbed, threadlike tube that delivers a paralyzing sting when propelled into attackers and prey; also called a stinging cell.
stinging cells of coelenterates.
microscopic, harpoon-like stinging capsule manufactured by all cnidarians (= coelenterates)
cellular organelle common in polyps; may be adopted by their predators; a sac containing a long coiled tube with Poison "harpoon" tip ejected by water pressure to trap prey

A stinging cell found on the tentacles of cnidarians.
a specialized cell in the tentacles of cnidarians (Phylum Cnidaria, jellyfish, corals, and anemones) and ctenophores (Phylum Ctenophora, comb jellies). Each nematocyst typically contains a barbed and/or venomous coiled thread that can be ejected in defense or to capture prey. a specialized cell in the tentacles of cnidarians (Phylum Cnidaria, jellyfish, corals, and anemones) and ctenophores (Phylum Ctenophora, comb jellies).
