Overview

Comprehensive Description

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. Young colonies are often thinly encrusting but more mature ones form a soft, compact network of anastomosing thin walled tubes. This species may be confused with Leucosolenia botryoides and other Leucosolenia species which are also comprised of thin walled tubes, however in C. coriacea there are no erect free branches.

This sponge is usually found on clean rock surfaces in the shallow sublittoral and also under overhangs and boulders on the shore. It is often found associated with the ascidian Dendrodoa grossularia in surge gullies but also in sheltered caves.

Clathrina coriacea

Clathrina coriacea is a species of calcareous sponge belonging to the family Clathrinidae.

This species occurs as flat white or yellow encrustations up to 3 cm in diameter with a central osculum. Close inspection reveals a tightly-knit latticework of tubes. The spicules are all of a similar shape, three-rayed triactines.

This is largely a shallow-water species though it has been recorded at depths of up to 650 m. The substrate is often rock but this sponge is also common on kelp holdfasts and on other sponge species.

This species is found along east Atlantic coasts from the Arctic all the way to South Africa.
