Diagnosis
Massive-lobate, encrusting, tubular, branching or flabellate sponges, often of considerable size, with smooth surface provided with small rounded and/or key-hole shaped apertures. Colour usually orange or brownish orange. Consistency toughly compressible, firm. No ectosomal specialisation. Choanosomal skeleton is an isotropic or anisotropic, occasionally irregular, system of spongin fibres. The main fibres are distinguishable by a core of megascleres, both main and interconnecting fibres are profusely echinated by megascleres. Spicules verticillate styles or oxeas. 34 nominal species distributed over most tropical waters; a single species occurs in the Mediterranean. The genus has not been recorded from the tropical East Pacific and tropical West Africa.
