Pallid ghost crab (Ocypode pallidula)
These crabs are small (usually under 3 cm carapace width) scavengers that live in high intertidal to supertidal areas where there is sand (and are thus also called sand crabs). They are indigenous to the Hawaiian islands and are active during the day. They are called ghosts because of their ability to disappear from sight almost instantly, scuttling at speeds up to 10 miles per hour, while making sharp directional changes. They also burrow into the ground.
