One of the mysteries of the English language finally explained.
The central gastric cavity of a coelenterate.
- ‘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.’
- ‘Water entering the coelenteron through the mouth leaves the body through the pores.’
- ‘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.’
- ‘This means they have just one opening into the coelenteron which serves as both a mouth and an anus.’
- ‘The oral tentacles then pass the paralysed prey to the mouth and into the coelenteron for digestion.’
