Diagnosis
Massive, barrel-shaped, tubular or lobate-digitate sponges. Surface with single or multiple conules or blunt broad tubercles or mounds, microscopically smooth, slippery and rubbery. Ostia radiate in stellate formation in shallow rounded depressions, oscules apical with low fleshy raised collars. Texture extremely tough, almost cartilaginous, fleshy, elastic. Colour in life cream base with pale purple-pink, and mottled with deep reddish brown and yellow brown. Skeletal arrangement plumoreticulate with huge thick hollow fibres optically visible, connected sparsely by thin secondary fibres. Ectosome dense, highly collagenous, distinct from the underlying choanosome, with layers of collencytes and collagen fibrils parallel to the surface. Megascleres are strongyloxeas, with a faint subterminal swelling at the proximal end, with the distal end oxeote or more typically strongylote. Microscleres are two size categories of spinorhabds. Sponges incubate huge bright orangeyellow larvae. (Modified from Kelly-Borges & Vacelet 1995).
