Common name: Homoscleromorpha sponges

Homoscleromorpha is a class of marine sponges characterized by a unique basement membrane and the absence of a true skeleton. These sponges are known for their relatively simple morphology and small size. They often form encrusting mats on rocks or other substrates in shallow waters. Homoscleromorphs are important in reef ecosystems for their role in nutrient cycling and as a habitat for microorganisms. Hobbyists appreciate them for their unique textures and contributions to a balanced reef tank.
