To review:

The reproductive and locomotive difference between the polyp and the medusa forms of the cnidarians and trade off with the reverse development.

Introduction:

Cnidarians are invertebrate, radially symmetrical, and marine animals that belong to phylum Cnidaria.

They possess Cnidoblasts (stinging cells) on their tentacles, and are thus called as cnidarians.
