Behavior

Ghost crabs do unusual things.

Did you know that a ghost crab can run nearly 10 miles per hour!?! At night they go down into the ocean water and let the sea water go into their gills for oxygen before they go back to their burrows at night. http://www.naturalsciences.org/funstuff/notebook/inverts/ghostcrab.html

Ghost crabs can dig a tunnel up to three or five feet deep. Their tunnels are not straight down; they're diagonal.

The ghost crab tunnels go down 4 feet into the ground at a 45 degree angle, creating1-2 inch wide holes, which speckle the beach. At dusk, these crabs will sprint to the ocean in order to obtain oxygen from the water which washes there gills
