Ophioderma longicauda

Snake brittle star

   Ophioderma longicauda is a brittle star of up to 15 cm in diameter with a central disc of 2,5 cm in diameter. The disc surface is smooth, covered on its two sides by tiny spherical grains visible under magnifying glass. The long smooth arms are cylindrical and tip-tapered. The colour is red to dark brown, the arms may have clearer bands. It lives on rocky bottoms and can move quickly thanks to the undulatory movements of its arms.
It is found from surface to 70 m deep in the Mediterranean Sea and in the Atlantic up to the Western Brittany coasts where it is rather rare.
