Defining characteristics of Cnidaria
-true tissues (diploblastic with an endo and ectoderm layer)
-radial symmetry
-nerve net nervous system (statocysts and ocelli)
-incomplete digestive system (mouth=anus)
-alternation of generations
-cnidocytes, nematocytes, tentacles, bells, etc.
-predators
-reproduce asexually by budding and sexually with motile gametes
-found in both freshwater and saltwater
-medusa and polyp stages
-3 classes; hydrozoa, anthozoa, and scyphozoa
