Which group of animals has two variations in their basic body plan, a medusa form and a polyp form?

Answer 1

Coelenterates have two body forms polyp and medusa.

The three classes of coelenterates are Hydrozoa, Scyphozoa, and Anthology. Hydrozoans have a polyp form predominant, meaning that most of their life exists in a polyp former. Scyphozoa are animals that resemble jellyfish and have a polyp stage that is only larval. Anthozoa are organisms that search for anemones and corals and have a polyp stage that is mostly present. Polyp and medusa are alternating forms.
