Oscula Study of a Sponge

Absence of oceanic water currents leaves wave action as the major source of mixing and water movement. A possible advantage for C. reniformis specimens to acquire larger sized oscules might be described with the need of catching desired food particles in a water movement zone affected by wave action. Continuous oscillation of particles in a wave action could make it harder to catch desired particles for a sponge with small sized osculas….
