  supertype:  phylum  (biology) the major taxonomic group of animals and plants; contains classes
  member of:  subkingdom_Metazoa
  member:  coelenterate__cnidarian  radially symmetrical animals having saclike bodies with only one opening and tentacles with stinging structures; they occur in polyp and medusa forms
  member:  polyp  one of two forms that coelenterates take e.g. a hydra or coral: usually sedentary and has a hollow cylindrical body usually with a ring of tentacles around the mouth
  member:  medusa  one of two forms that coelenterates take: is the free-swimming sexual stage in the life cycle of a coelenterate and has a gelatinous umbrella-shaped body and tentacles
  member:  class_Scyphozoa__Scyphozoa  coelenterates in which the polyp stage is absent or at least inconspicuous: jellyfishes
     member:  scyphozoan  any of various usually free-swimming marine coelenterates having a gelatinous medusoid stage as the dominant phase of its life cycle
     member:  genus_Chrysaora__Chrysaora  a genus of Scyphozoa
        member:  Chrysaora_quinquecirrha  a type of jellyfish
  member:  jellyfish__medusa__medusan  any of numerous usually marine and free-swimming coelenterates that constitute the sexually reproductive forms of hydrozoans and scyphozoans
  member:  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
     member:  hydrozoan__hydroid  colonial coelenterates having the polyp phase dominant
     member:  genus_Hydra  hydras
        member:  hydra  small tubular solitary freshwater hydrozoan polyp
     member:  order_Siphonophora__Siphonophora  marine colonial hydrozoans
        member:  siphonophore  a floating or swimming oceanic colony of polyps often transparent or showily colored
        member:  genus_Nanomia  a genus of Siphonophora
           member:  nanomia  small creatures resembling pieces of fuzzy rope; each with a cluster of swimming bells serving as the head and long elastic tentacles for drawing in prey
        member:  genus_Physalia__Physalia  Portuguese man-of-war
           member:  Portuguese_man-of-war__man-of-war__jellyfish  large siphonophore having a bladderlike float and stinging tentacles
     member:  genus_Sertularia__Sertularia  sessile hydroid that forms feathery colonies
        member:  sertularian  feathery colony of long-branched stems bearing stalkless paired polyps
  member:  class_Anthozoa__Anthozoa__Actinozoa__class_Actinozoa  no alternation of generations the medusoid phase being entirely suppressed: sea anemones; corals
     member:  anthozoan__actinozoan  sessile marine coelenterates including solitary and colonial polyps; the medusoid phase is entirely suppressed
     member:  order_Actiniaria__Actiniaria__Actinaria__order_Actinaria  sea anemones
        member:  sea_anemone__seaanemone  marine polyps that resemble flowers but have oral rings of tentacles; differ from corals in forming no hard skeleton
        member:  actinia__actinian__actiniarian  any sea anemone or related animal
        member:  genus_Actinia__Actinia  a genus of sea anemone common in rock pools
     member:  order_Alcyonaria__Alcyonaria  corals and sea anemones having eight branches
        member:  suborder_Alcyonacea__Alcyonacea  comprising the soft corals
        member:  family_Pennatulidae__Pennatulidae  sea pens
           member:  genus_Pennatula__Pennatula  type genus of the family Pennatulidae: sea pens
              member:  sea_pen__seapen  fleshy featherlike warm-water colonies
        member:  suborder_Gorgonacea__Gorgonacea__Gorgoniacea__suborder_Gorgoniacea  red corals and sea fans
           member:  gorgonian_coral__gorgoniancoral__gorgonian  corals having a horny of calcareous branching skeleton
     member:  order_Madreporaria__Madreporaria  stony corals
        member:  stony_coral__stonycoral__madrepore__madriporian_coral__madriporiancoral  corals having calcareous skeletons aggregations of which form reefs and islands
        member:  genus_Maeandra__Maeandra  brain corals
           member:  brain_coral__braincoral  massive reef-building coral having a convoluted and furrowed surface
        member:  genus_Acropora__Acropora  coelenterate genus of order Madreporaria, including staghorn corals
           member:  staghorn_coral__stag's-horn_coral  large branching coral resembling antlers
        member:  genus_Fungia__Fungia  mushroom corals
