__Fiddler Crabs:__

Fiddler crabs are most related to ghost crabs of the genus Ocypode. ( http://en.wikipedia.org/wiki/Fiddler_crab ) Male fiddler crabs have one huge claw, and ghost crabs do not. (Exploring the Seashore, National Geographic Society,1988)

Ghost crabs belong in the same family as fiddller crabs. There are 20 species of ghost crabs, but //O. quadrata// is the only one found on the east coast of the United States. By David Knott

__Ghost Crabs of Australia:__

The ghost crab stays in the cool protection of its burrow by day and scuttles down to the water at twilight to hunt. The burrow, which is built quite high up on the shore (sometimes over 100 m from the sea), can be over 1 m deep. ( http://www.faunanet.gov.au/wos/factfile.cfm?fact_ID=65 )

Birds and fish eat Ghost Crabs. In Australia, their gohst crabs are found in the sub-tropical and tropical habitats.( http://www.amonline.net.au/wild_kids/seashores/ghost_crab.htm )
