Overview

Comprehensive Description

Description

This sponge consists of a bundle of yellow anastomosing tubes. The tubes form discrete groups converging on single conspicuous oscules and are typically about 3mm in diameter. Clathrina coriacea is similar but consists of tubes of smaller diameter. It exists in a range of colour forms but probably not the distinctive yellow of Clathrina clathrus.

Distribution

A common Mediterranean species; the status of this species in UK waters needs investigation. Confusion of nomenclature of calcareous sponges may mean that this species has been reported in error from NE Atlantic waters.

Clathrina clathrus

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

This yellow (occasionally white) sponge, up to 10 cm in diameter, usually appears cushion-shaped at a distance (its close relative Clathrina coriacea is normally flatter in appearance). Close-up the sponge can be seen to consist of a tangled mass of tubes (these tubes are thicker and less tightly knit than in C. coriacea and there is no osculum as found in that species). Like C. coriacea, the spicules are exclusively three-pointed triactines.

This is a shallow-water species found in the Mediterranean and on Atlantic coasts of Europe as far north as the British Isles.
