pol′yp•ous, adj.

pol·yp

(pŏl′ĭp)
A cnidarian in its sedentary stage. Polyps have hollow, tube-shaped bodies with a central mouth on top surrounded by tentacles. Some cnidarians, such as corals and sea anemones, only exist as polyps, while others turn into medusas as adults or lack a polyp stage completely. Compare medusa.

polyp

A tissue growth projecting from the skin or mucous membrane, such as inside the nose.
