Burrows of Ocypode quadrata (Fabricius) as related to slopes of substrate surfaces
Journal of Paleontology, 1986Diameter, dip and orientation of burrows of the ghost crab Ocypode quadrata (Fabricius) were measured in back-beach areas: dune faces, dune crests, swales, blowouts and washover fans. Slope direction of the substrate at each burrow site was also measured. Results support three conclusions. First, burrow diameter increases landward.

Changes in the behaviour ofOcypode quadrata(Fabricius, 1787) after experimental trampling
Journal of the Marine Biological Association of the United Kingdom, 2018AbstractThe effects of trampling are usually confounded by the diffuse impacts of the urbanization of sandy beaches. We performed a controlled experiment on a beach with low visitation rates to test the hypothesis that ghost crabs avoid building their burrows on impacted plots as a result of the compacted sediment, and they migrate to non-trampled ...

Landmark use by ghost crab (Ocypode quadrata) during wayfinding in a complex maze
Behavioural ProcessesSpecies of crab have been shown to spatially track and navigate to consequential locations through different processes, such as path integration and landmark orienting. Few investigations examine their ability to wayfind in complex environments, like mazes, with multiple intersections and how they may utilize specific features to benefit this process ...

Journal of Experimental Marine Biology and Ecology, 1978
Abstract Food habits and ecological role of the ghost crab. Ocypode quadrata ( Fabricius) on a North Carolina barrier beach have been investigated in field and laboratory studies. Despite previous reports that they are scavengers, the crabs spent little time in ureas where drifted material accumulated.

Evaluating sampling techniques for measuring ghost crab (Ocypode quadrata) burrow density
2017Through field sampling, this study compares the ghost crab burrow densities acquired using a Fixed-Area sampling method to those measured using the Belt Transect method commonly used in ecological research. The two methods differ in area sampled per study site as well as distribution of area sampled along the beach, from dune to swash.

La taille a la puberte du Crabe Ocypode quadrata (Fabr.), de la cote centrale du Texas, a ete determinee d'apres quelques donnees histologiques et la croissance relative. Les relations de la largeur de la carapace a la longueur et a l'epaisseur de la carapace, la longueur du pedoncule oculaire et la longueur totale de la troisieme patte ambulatoire ...

Chesapeake Science, 1976
The ghost crab Ocypode quadrata (Fabricius) is both a scavenger and an active predator which can be seen prowling the sea wrack left by the tide, especially at night. Williams (1965) stated that the crabs often will feed upon beached fish and I have seen them consuming portions of dead bluefish and striped mullet.
