Clathrina
''Clathrina'' is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in ''Clathrina'' were transferred to the newly erected genera ''Arthuria'', ''Ernstia'', ''Borojevia'', and ''Brattegardia'' in 2013. The name is derived from the Latin word "''clathratus''" meaning "latticed". ==Description== Calcinea in which the cormus comprises anastomosed tubes. A stalk may be present. The skeleton contains regular (equiangular and equiradiate) and/or parasagittal triactines, to which diactines and tripods may be added. Asconoid aquiferous system.
