Phylum bryozoa.

Lophotrochozoa are also protostomes, in which the blastopore, or the point of invagination of the ectoderm (outer germ layer), becomes the mouth opening into the alimentary canal. This developmental pattern is called protostomy or “first mouth.”. Protostomes include acoelomate, pseudocoelomate, and eucoelomate phyla.28 may 2021 ...
