pennatulacea		interaction of 2 organisms; continuum
cnidae		cnidarians have a mutualistic relationship with
manubrium		synapomorphy that first shows up in this phylum
spirocysts		have high energy cost in light of reproduction
colloblasts		analogous to cnidae, ctenophores have them
dactylozooids		how polyps produce medusae
anthozoa		class containing true jellyfish
polyp		type of digestive system
mesoglea		only stage of an anthozoa
operculum		divide GVC and provide surface area for digestion
zooxanthellae		order of sea pansies/pens
scleractinia		order of cnidarians not colonial in class hexacorallia
scyphozoa		class containing sea anemones and soft corals
GVC		unique stinging/adhesion structures
gorgonacea		type of reproduction in anthopleura
gastrozooids		a colony within a colony
cormidium		order of stony corals
actinlaria		how polyps in colonies are connected
strobilation		upon stimulation this causes the operculum to be thrown open
GVC		used for feeding in hydrozoa
pharynx		order of soft corals in class that has 8 tentacles
incomplete		defense and prey capture in hydrozoa
muscles		where mouth of jellyfish is found
velum		runs from mouth to GVC
mesenteries		functions in excretion, digestion, hydrostat, fluid transport
radial		sticky, threadlike used for feeding
eggs		true jellyfish do not have, the rim around bell base
fission		middle layer derived from ectoderm
symbiosis		type of exoskeleton of many scleractinia
cnidocil		type of symmetry
calcareous		a hinged lid covering capsule in hydrozoa and scyphozoa
