Description
1) A class of primitive, multicellular animals of the phylum Porifera. Sponges sold commercially are the fibrous skeletal remains of these animals. The sponge skeleton is flexible and absorbent. It is a porous structure composed of siliceous cells bound in a spongin (fibrous protein) matrix. Natural sponges were used by the ancient Greeks and Romans for applying paint, cleaning and for drinking.
2) Absorbent cellulose fibers from several types of fruits or gourds that are used as a washing sponges and filters. See Loofa sponge.
3) A foamed plastic that simulates the absorbency of natural sponges. See also Cellulose sponge, rubber sponge and PVA sponge.
