polyp - one of two forms that coelenterates take (e.g. a hydra or coral): usually sedentary with a hollow cylindrical body usually with a ring of tentacles around the mouth; "in some species of coelenterate, polyps are a phase in the life cycle that alternates with a medusoid phase"
medusan, medusoid, medusa - one of two forms that coelenterates take: it is the free-swimming sexual phase in the life cycle of a coelenterate; in this phase it has a gelatinous umbrella-shaped body and tentacles
class Scyphozoa, Scyphozoa - coelenterates in which the polyp stage is absent or at least inconspicuous: jellyfishes
jellyfish - any of numerous usually marine and free-swimming coelenterates that constitute the sexually reproductive forms of hydrozoans and scyphozoans
class Hydrozoa, Hydrozoa - coelenterates typically having alternation of generations; hydroid phase is usually colonial giving rise to the medusoid phase by budding: hydras and jellyfishes
