Each tentacle of a hydra is layered with highly specialized stinging cells called cnidocytes. The Cnidocytes contain specialized structures called nematocysts that, when contacted with prey, can fire neurotoxins paralyzing the prey.

Hydra do not have a recognizable brain or muscles. The nervous system of Hydra is a nerve net.

Hydra extend their body to maximum length when feeding and slowly extend their tentacles. Upon contact with prey, the nematocysts on the tentacle fire into the prey while the tentacles coil around the prey.
