Ghost Crabs are found in tropical waters, from the Kimberley in Western Australia, Northern Territory, Queensland to Sydney, New South Wales. They either head back to their burrows or plunge into the sea to escape intruders.Ghost crabs are negatively affected by human activity on sandy beaches, such as sand trampling by foot traffic, the building of Taylor, Jennifer R. A., et al. Found on beaches of the lower Chesapeake Bay, particularly those close to the ocean. These crabs are able to chair their coloring to match their surroundings, making them less vulnerable to predators. The "whip" of their Ghost crab species can be most reliably identified by means of the area where they were recovered, the presence of "horns" (styles) on their eyestalks (exophthalmy), the pattern of Exophthalmy is exhibited by seven species in the subfamily: Stridulating ridges also differ from species to species, with some displaying rows of tubercles, others displaying rows of smaller ridges (striae), or a combination of both.
They also feed on mole crabs, clams and the eggs of loggerhead turtles.

The regions of the carapace are usually not clearly defined. (Becky Gregory/Flickr)A ghost crab near the beach at Fisherman Island National Wildlife Refuge on Virginia's Eastern Shore
Characteristics of the subfamily include one claw being larger than the other, thick and elongated eyestalks, and a box-like body.
Ghost crabs are omnivorous, feeding on insects, filter-feeders (like clams and mole crabs) and the eggs and hatchlings of loggerhead turtles.
The average life span of a ghost crab is three years.
Ghost crabs are active on coastal beaches in the Chesapeake Bay region from spring through autumn. 286, no. Common predators include raccoons, shorebirds and gulls. They are used by ghost crabs for communication.Both exophthalmy and stridulating ridges, however, can not be reliably used to determine Ghost crabs are swift runners, darting away at the slightest sign of danger. Older individuals dig their burrows farther from the sea, some starting as much as 400 m (1,300 ft) inland. The Ghost Crab stays in the cool protection of its burrow by day and scuttles down to the water at twilight to hunt. Other behaviours and adaptations. They have evolved to produce sounds during agonistic interactions to produce rasping noises with their claws.
Burrows can be up to four feet deep, and are often found hundreds of feet from the water's edge. The Atlantic ghost crab lives in burrows in sand above the strandline. Range extends as far north as Rhode Island and as far south as Brazil.
Burrows can be up to 1.3 m (4 ft 3 in) deep, and can be closed off with sand during hot periods.

Young ghost crabs are much darker than adults, with carapaces colored a mottled gray and brown. Ghost Crabs feed on sea turtle hatchlings, turtle eggs, clams, insects, and other crabs. Females carry developing eggs under their bodies before releasing them into the water, where larvae will develop.
However, they can only remain under water for a limited amount of time, as the… Mating can occur throughout the year, and often takes place in or near the burrow of a male. Ghost crabs dig deep burrows near the intertidal zone of open sandy beaches. These are very important in identifying species as they are displayed by both adults and juveniles (though they may be absent in newly regenerated claws). Distribution.
Younger ghost crabs burrow close to the water, while older ghost crabs burrow higher up on the beach. Young ghost crabs are much darker than adults, with carapaces colored a mottled gray and brown.
They must periodically wet their gills with seawater, usually by taking water from moist sand or by running into the surf and letting the waves wash over them.
Common on coastal beaches; they dig burrows in the sand, where they seek shelter from the sun and "hibernate" during the winter.
