hey mate...

here is your answer...

Highest degree of polymorphism is found in Cnidria.

Polymorphism is the occurrence of multiple morphological forms. It is common in phylum Coelenterata which have an asexually reproducing form, called as a polyp, and sexually reproducing stage called as medusae. The members of Cnidaria have life cycles that alternate between two forms: Asexual polyps (generally sessile, with the body as a vase-shaped form), which are nutritive in function; and sexual, free-swimming forms called medusae (singular medusa, the body in a bell-shaped form), which are reproductive in function.
