Minchinellidae in the World Register of Marine Species
Minchinellidae is a family of calcareous sponges, members of the class Calcarea.[1] It is the only family in the monotypic order Lithonida. The families Petrobionidae (genus Petrobiona)[2] and Lepidoleuconidae (genus Lepidoleucon)[3] have also sometimes been placed within Lithonida, though more recently they have been moved to the order Baerida.[4] Thanks to their hypercalcified structure, minchinellids have a fossil record reaching as far back as the Jurassic Period.[3][4]
Description
Minchinellids are hypercalcified sponges. They have a robust skeleton of tetractine (four-rayed) calcareous spicules. The tetractine spicules are propeller-shaped, with three curved actines (rays) radiating perpendicular to a straight basal actine. These spicules may be linked by their basal actines or cemented together by calcite. The skeleton is reinforced with layers of loose diapason (tuning fork-shaped) spicules. Minchinellid sponges have a leuconoid canal system.[3][4]
