*Life Cycle:
-Share some characteristics with Cnideria: tissue organization, biradial symmetry, a gastroascular cavity, and a nerve net.
-They differ from cnidarians in that they have a cellular mesoglea which is considered a third tissue layer, making them triploblastic.
-they have an anal opening and a separate opening for the mouth, giving them a complete gut.
-they are monoecious with external fertilization.
