Does a sea sponge has radial symmetry?

No, a sea sponge does not have radial symmetry. Radial symmetry is a type of body plan in which the body is arranged around a central axis, like the spokes of a wheel. Sea sponges, on the other hand, have an asymmetrical body plan, meaning that their bodies are not symmetrical along any axis. Instead, sea sponges have a more irregular shape, with different parts of the body serving different functions.
