sea sponges
Porous marine animals
Sea sponges are simple aquatic animals that attach to underwater surfaces and filter nutrients from the water.
Despite their plant-like appearance, they are among the oldest multicellular organisms.
Natural sea sponges have been harvested for bathing and cleaning since antiquity, prized for their softness and absorbency: She prefers a natural sea sponge to a synthetic one.
