Clathrina coriacea is a species of calcareous sponge belonging to the class Calcarea and family Clathrinidae. Species in the genus Clathrina are composed of calcium carbonate tube-like skeletons containing spicules. The sponge can be located in shallow waters widely distributed along North Atlantic coasts, as well as on other coasts.

Clathrina coriacea Description: This sponge is usually white but can also be grey, pale rose, orange or sulphur yellow in colour. Several new species have recently been described from the NE Atlantic and it is likely that different forms currently identified as Clathrina coriacea are in fact distinct species.

Clathrina coriacea (Montagu, 1818) Order : CLATHRINIDA Family : Clathrinidae Consists of three dimensional network of anastomosing thin walled tubes, which form a compact, low-lying anastomosing mass attached directly to the substrate. There are no erect free branches. Usually white, but can be grey, pale rose, orange or sulphur yellow.
