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".
Species of Clathrina have a tubular organization as all species of the family Clathrinidae, with the cormus composed of anastomosed tubes. The skeleton contains spicules in the form of triactines and/or tetractines, sometimes with diactines, tripods and tetrapods as well. The choanoderm is usually flat, never forming folds when the sponge is extended.
There are over 40 species assigned to Clathrina as of 2013.
