About Dardanus arrosor (J.F.W.Herbst, 1796)
For Dardanus arrosor, the carapace can reach a length of 6–8 centimetres (2.4–3.1 in). Its body color varies from bright red to bright orange. The eyestalks are robust, not very long, and dilated at the tip, with alternating red and white streaks. The eyes are bluish. Its claws bear hair-like spines and warty tubercles. The left claw is more developed than the right claw, and the tip of both claws is black or yellowish. The abdomen is asymmetrical, bare, and hidden inside a gastropod shell. This is a widespread species found along Atlantic coasts, the Mediterranean Sea, the Red Sea, and the Indo-West Pacific (including Japan, New Zealand, and the Philippines). It inhabits the continental shelf and continental slope, and typically lives on sandy substrates, coastal detritic bottoms, and bathyal muds, ranging from shallow depths of a few meters down to 750 metres (2,460 ft).
