The horned ghost crab (Ocypode ceratophtalmus), also known as the horn-eyed ghost crab is a ghost crab found in the Indo-Pacfic region (excluding the Red Sea), from the East African coast to the islands of the Philippines and from Japan to the Great Barrier Reef.
Biology[]
As their name suggests, horned ghost crabs possess eyestalks that extend beyond the eyes into long points, which are longer in adults, and shorter (or absent) in juveniles. These crabs have a box-shaped body that measures 6-8 cm (2.4-3.1 in) across the carapace, with darker markings towards the rear in an H shape. The outer edges of the eye-sheaths are sharp, broadly triangular, and distinctly point sideways in larger individuals. Horned ghost crabs can reach speeds of up to 2.1 m/s (6.9 ft/s, 4.7 mph, or 7.56 km/h).
