Enterocoely (adjective forms:
enterocoelic and
enterocoelous) is a process by which some animal
embryos develop. In enterocoely, a
mesoderm (middle layer) is formed in a developing
embryo, in which the
coelom forms from pouches "pinched" off of the digestive tract (also known as the embryonic gut, or
archenteron). This type of coelom formation occurs in
deuterostome animals, which for this reason are also known as
enterocoelomates.
