Genus Aaptos Gray, 1867 Diagnosis (sensu van Soest 2002): Sponges are lobate, spherical, subspherical or globular often consisting of confluent globular or lobate units. Surface smooth or tuberculate­papillate, usually rough to the touch. Some species show a distinct colour change when taken out of the water. In cross section, the outer region is often fibrous and may be considered as a cortex which grades into the choanosome. Skeleton strictly radial, with tracts and single spicules issuing from the centre of the lobe or globular body. At the surface the tracts fan out and form a dense palisade consisting of smaller spicules intermingled between the ends of the larger spicules. Spicules are strongyloxeas, in three overlapping size categories; the intermediate and smaller spicules are occasionally oxeas, styles or tylostyles.
