Quote:
Cnidarian bodies have two or sometimes three layers. A gastrovascular cavity (coelenteron) has a single exterior opening that serves as both mouth and anus. Often tentacles surround the opening. Some cells are organized into two simple nerve nets, one epidermal and the other gastrodermal, that help coordinate muscular and sensory functions.

I want tentacles surrounding MY anus!
Stem cell research will provide this option to be open in the future, no doubt ... and we'll all be at peace on the island of Dr. Moreau.
