Quick Summary
Microscleres are small sponge spicules that primarily function in protection and also aid in support. These minute structures are typically associated with a single cell within the sponge. Sponges, which are unusual animals lacking definite organs, utilize their skeletons, composed of either mineral or protein components, for various functions. The mineral skeletons are formed by units called spicules, which are categorized as either megascleres for support or microscleres for protection and additional support.12
