Also containing the order Lobata and the primitive Cydippida, they are best characterized by eight rows of fused plates situated along their bodies, each composed of thousands of related cilia, which aid in propulsion.
The two planes of symmetry in this phylum are known as the stomodeal plane and the torial plane. Their pharynx is connected aborally with the infundibulum, from which their common canal system extends, with their peripheral canals containing rosettes. They possess sticky cells called colloblasts, typically located on retractile tentacles, except in the order Beroida, which allows them to capture prey without possessing stinging cells.
