This is called protostomy or “first mouth.” In protostomy, solid groups of cells split from the endoderm or inner germ layer to form a central mesodermal layer of cells. This layer multiplies into a band and then splits internally to form the coelom.

View the preserved tapeworm and the slides of the tapeworm scolex (head) and proglottids (reproductive bodies). The preserved annelida specimens will be on display, but may differ from the ones directly mentioned in the lab handout. The phyla we viewed today were the porifera, the cnidaria, the nematoda and the arthropoda.

As you peel this piece of carapace away, it may be necessary to reach underneath with the point of a scissors or needle to brush away and detach any tissue from the interior of the animal that is attached to the carapace.
