Archenteron
[Gr. arche - primitive; Gr. enteron - intestine]. The gut cavity formed by gastrulation in metazoan embryos; formed by infolding of part of the outer surface of the blastula and opening to exterior via blastopore.
enteron
The tubular passage that extends from mouth to anus.
epidermis
(1) the dermal tissue system in plants. (2) the outer covering of animals.
archenteron - cavity formed during gastrulation by invagination of the vegetal plate cells (in sea urchin) or involution of cells at the blastoporal lip (in amphibians); it will become the interior of the primitive gut.
archenteron
(ark-en-ter-on) [Gk. arch, first, or main + enteron, gut]

Enteropneusta A class of hemichordates whose members live in burrows in shallow marine water. Their bodies are divided into three regions: proboscis, collar, and trunk. Acorn worms.
The cavity is also called a coelenteron and for many years the name of this phylum was Coelenterata. There is no anus.
Sexual reproduction produces a free-swimming, ciliated larva called a planula.
However, in protostomes the initial opening (the archenteron) develops into the mouth, and an anus forms separately. In deuterostomes this is reversed.
