Porifera Overview and Key Structures

A large opening on a sponge through which filtered water is expelled.

Needlelike structures that give support and protection to the sponge body and prevent small animals from entering the sponge's internal cavity.

Collar cells that line the body cavity and have flagella that circulate and create water currents in sponges.
