Ocypode

Ocypode is a genus of ghost crabs found on sandy beaches worldwide. These crabs are characterized by their large, box-shaped carapace, which is often pale in color, helping them to camouflage with the sand. They possess prominent eyes on stalks, which can move independently, allowing for a wide field of vision and excellent predator detection.

Ghost crabs are primarily nocturnal, emerging from their burrows at dusk to forage for food. Their diet consists mainly of small invertebrates, carrion, and occasionally plant matter. They are known for their speed, capable of running sideways across the sand at impressive velocities to escape danger or pursue prey.

These crabs are adept burrowers, creating deep, U-shaped holes in the sand that serve as shelter from predators and the midday sun. The depth of these burrows can vary depending on the species and the environmental conditions.

The genus Ocypode includes several species, such as Ocypode quadrata (Atlantic ghost crab) and Ocypode ceratophthalmus (horned ghost crab). While they share many common traits, there are subtle differences in their morphology and geographical distribution. Ghost crabs play a role in beach ecosystems by scavenging and aerating the sand through their burrowing activities.
