Corsica, France, 25 meters, WD
Echinus melo is a globular sea urchin of up to 17 cm in diameter. Spines are scarce and of two types: short thin greenish-yellow spines, called secondary spines, and long thin olive-green spines with whitish tips, called primary spines. Primary spines are rarer: they are laid out in a single row on the interambulacral plates. Test colour is variable: pale yellow with orange spots or sometimes greenish yellow. It lives on rocks from 25 m to depths down to several hundred meters, but it is abondant around 40 m deep.
Echinus melo is found in the Mediterranean Sea and in the Atlantic Ocean from the Azores to the Bay of Biscay.
