What is the function of cnidarian tentacles?
They use their tentacles to sting their prey. ------- In addition to envenomating prey, cnidarians use their tentacles to bring their food towards their oral cavity and to provide defense against predators. Sessile cnidarians can also use their tentacles for locomotion, using sticky nematocysts for adhering to the substrate and then pulling themselves along a surface by retraction of those tentacles. Certain box jellyfish species (notably, Carybdea sivickisi) use their tentacles during courtship behavior- the males use them to hold onto a mate, and the females use them to ingest the presented sperm package (spermatophore) into their cavities in proximity to their eggs. Some small jellies also use their tentacles to hold onto eel grass for reasons that are yet to be fully understood, but probably are related to camouflage.
