    SKELETAL STRUCTURES IN PORIFERA. Skeletal structures of sponges are spicules and spongin fibres. Spicules are formed by carbonates of lime or silica in the form of needle like pieces. Spongin fibres are composed of a silk-like scleroprotein. SPICULES. The spicules constitute major part of skeletal system, which are secreted by special mesenchymal cells called scleroblasts.

    In all three types of structure the cross-section area of the choanocyte-lined regions is much greater than that of the intake and outlet channels. This makes the flow slower near the choanocytes and thus makes it easier for them to trap food particles. For example, in Leuconia, a small leuconoid sponge about 10...Kingdom: Animalia

Sponge spicule - Wikipedia
