Polyps may be solitary individuals or members of a cnidarian colony. They consist of a cylindrical trunk, fixed at one end, with a mouth at the other end, surrounded by a ring of tentacles. Many polyps reproduce by budding, and may form colonies. Some reproduce sexually, fertilized eggs giving rise to new polyps, as in the case of Hydra and sea anemones. Others do not reproduce sexually, but produce medusae by budding and these reproduce sexually, their fertilized eggs giving rise to new polyps, as in the case of jellyfish.
