Anatomy of a Coral polyp

Polyps are one of two forms of the cnidarians. Polyps may be sexual or asexual. The other body form is the medusa. When medusae mate, the result may be polyps, when polyps replicate, the result may be medusae. The details vary between species. Certain animal species are polyps all the time. Jellyfish polyps turn into 10–15 jellyfish and die.
