Ligia italica is a marine isopod of 1 to 2 cm, dark grey with long antennae. Lives above the high-water mark on coastal rocks, never fully submerged. Extremely fast: its collective scatter when approached is spectacular. Detritivore, recycling beached algae and carrion. Very common across the Mediterranean and northeast Atlantic.
