polyps with different morphological forms that make up colonial cnidaria.

Produce planular larvae through sexual reproduction - Larvae that swim.

They swim by using 8 ciliary combs that are fused at the base. They are mostly planktonic and exclusively marine. Ctenophores are characterized by eight rows of cilia, which are used for locomotion. They lack stinging cells. they use colloblasts instead.
