The enterocoelic theory would raise no doubts if only Deuterostomia were
involved. Deuterostomia are, in fact, naturally derived from animals at the
ctenophore level. Important supplementary arguments in favour of the great
antiquity of ...

Enterocoelic Development : It is found in echino- derms and chordates (the
deuterostomes). The coelom arises by the outpocketing of the embryonic gut or
archenteron. These pouches pinch off, enlarge and come to lie in the blastocoel.
V. B. Rastogi, B. Kishore, 1997
Thus, in the early stage, the mesodcrm formsa series of segmentally arranged
mesodermal or enterocoelic pouches. Separation of these pouches begins from
the anterior end and proceeds backwards. Each pouch is now a hollow sac
called ...

Coelom is enterocoelic and not schizocoelic as in annelids. The flow of blood in
main blood vessels is in opposite directions in the two groups. Above all, the
three basic chordate characters of Cephalochordata are not present in Annelida.

But the various gastraea-type phases that these authors support, being so closely
tied to enterocoelic theories, have difficulty in accounting for the diversity of
modem coelomate embryology (chapter 5) and for the very existence of many ...

Principles of Comparative Anatomy of Invertebrates: Organology
The enterocoelic theory thus includes the gono- coelic theory, but in a somewhat
modified form; the homologues of the coelom are not the genital follicles of
turbellarians and nemertines, but the peripheral canals or chambers of
coelenterates.
