Cnidarians have two basic body forms, medusa and polyp.
Two major adult body types characterize the phylum: the medusa is typically a mobile pelagic organism, and the polyp is typically a sessile benthic organism.
Remaining undigested by the medusa , the small snail will devour its host from within, growing larger as its host is correspondingly diminished in size.
A medusa , or jellyfish, is part of the life cycle of just one major group of animals, the cnidarians.
Predation by an abundance of medusae on zooplankton and ichthyoplankton could affect the North Sea ecosystem through top-down and bottom-up mechanisms.
