Suberites domuncula reaches 25 cm diameter. Sponge (Suberitidae) Mediterranean and East Atlantic temperate with massive globular to elongated body orange to yellow-orange to orange-brown, smooth to slightly granular surface, scattered oscula. Remarkable ecological feature: grows preferentially on gastropod shells inhabited by hermit crabs (Pagurus), forming a mutualistic symbiosis where the sponge protects the hermit and the hermit moves the sponge to richer areas. Lives from 3 to 100 m on sandy and rocky bottoms. Fascinating Mediterranean dive photo subject for this association.
