Sponges are animals, fixed in the adult state (the larvae actually swim), and their whole body is adapted to filter large volumes of water. They are therefore active filter feeders, creating currents in the water, and gain their nourishment by retaining microscopic particles (detritus, bacteria, micro-algae) suspended in the water. Sponges are therefore suspensivores.

Sponges have no tissue or organs, and the filtration of water is carried out by their aquifer system: channels and small chambers lined with specialised cells (choanocytes) that create currents of water and retain nutritive particles.
