The two body forms of cnidarians are the polyp and the medusa. Polyps are typically sessile, tube-shaped organisms attached to a substrate, while medusae are free-swimming, umbrella-shaped organisms.
A mutually beneficial relationship between two biotic (living) organisms is called a symbiotic relationship.
