Environment: milieu / climate zone / depth range / distribution range
Ecology
Sessile. Temperate
Northeast Atlantic and Indo-West Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Rounded elevations and depressions on surface, with elevations echinated by the spicules. Tesselation absent. Megasclere: rounded base; apex usually blunt but sometimes sharp; styli faintly tylote, no oxea nor strongyla. Microsclere: very small chiasters; larger and more massive spherasters. Chiasters are most abundant at the surface, forming a close layer, rays: 6 to 9. Spherasters rarely spined; unevenly scattered through the ectosome; rare in the choanosome.
Known from rock pools (Ref. 88951).
Life cycle and mating behavior
