siliceous sponge

any sponge in which the main skeletal component is silica as opposed to calcium carbonate or fibrous organic materials only. More than 95 percent of all known sponge species have a siliceous skeleton and belong to the class Demospongiae (phylum Porifera). The siliceous skeleton is usually composed of discrete elements known as spicules that vary greatly in size and shape from species to species and are hence often used to aid species identification
