Echinaster (Echinaster) sepositus is a starfish of up to 20 cm in diameter, but which can reach sometimes up to 30 cm. It has five long cylindrical tapering arms surrounding a small central disc. Its surface is covered by numerous small craters and its colour is bright red-orange. It lives on rocky bottoms.
Echinaster (Echinaster) sepositus is found from 1 m to 250 m deep. It is common in the Mediterranean Sea, on the French coasts of the English channel and on the African coasts down to the Equator. In other areas of the North-East Atlantic Ocean, it is rare or even absent.
