Ocypode ceratophthalmus
Ocypode ceratophthalmus, the horned ghost crab[2] or horn-eyed ghost crab,[3] is a species of ghost crab. It lives in the Indo-Pacific region from East Africa to the Philippines and the Great Barrier Reef.[4] O. ceratophthalmus can be distinguished from other related crabs by the eyestalks extending beyond the eyes into long points,[5] which are longer in males, and shorter in females and juveniles.[3] The crabs have a box-shaped body, 6–8 centimetres (2.4–3.1 in) across the carapace, with a darker markings towards the rear in the shape of an H.[3] O. ceratophthalmus can run at speeds of up to 2.1 metres per second (6.9 ft/s).[6]
