Question

Name the two animal phyla which exhibit radial symmetry.

Answer 1

In the animal kingdom, there are two broad phyla that exhibit radial symmetry:

One of these is cnidaria, which include jellyfish, anemones, and corals. Jellyfish exhibit radial symmetry in four points around its center. The other phylum is echinodermata, such as sea stars, urchins, and sea cucumbers. Sea stars have what is called a pentamerous radial symmetry, meaning it is divided in five ways around its central point.
