The oral tentacles then pass the paralysed prey to the mouth and into the coelenteron for digestion.
In response to vigorous stimuli the longitudinal muscles contract and the mouth opens, forcing the water out of the coelenteron and flattening the sea anemone against the bottom.
Water entering the coelenteron through the mouth leaves the body through the pores.
This means they have just one opening into the coelenteron which serves as both a mouth and an anus.
The anthozoans are diploblastic animals developing from two epithelial germ cell layers: the ectoderm, facing the seawater, and the endoderm, facing the gastrovascular cavity or coelenteron.
