Hydrozoa- hydra
Anthozoa- corals,
anemones
Scyphozoa- jellyfish
Polyps- sessile
Medusa- use
hydrostatic skeleton
Contain tissues
Diploblasticectoderm and
endoderm
Radial symmetry

cavity
Tentacles
Hydrostatic skeleton
Nematocysts
Nematocysts on
tentacles paralyze
prey
Tentacles or oral
arms bring food to
mouth
Food enters
gastrovascular cavity
Heterotrophic
Extracellularenzymes secreted
into GV cavity
Intracellular- food
then incorporated
into cells
Waste leaves
