Vertical distribution by demographic groups of ghost crab Ocypode quadrata (Crustacea: Brachyura)
Biologia (Poland), 2014 The ghost crab Ocypode quadrata plays an important role in energy transfer between trophic levels, and has been widely used in evaluations of impacted environments. In order to provide data on the biology of this potential bioindicator species, the population structure and vertical distribution of individuals were studied on two beaches in southeastern

Mirror self-recognition in ghost crab (Ocypode quadrata)
Animal Cognition, 2023Mirror self-recognition has been examined primarily in vertebrate species, largely through the use of a mirror mark test. Recently, however, there has been growing interest in the notion that all animals likely need some form of self-representation to successfully interact with their environment (Kohda et al.

Deposit-feeding by the ghost crab Ocypode quadrata (Fabricius)
Journal of Experimental Marine Biology and Ecology, 1981Abstract Observations using a videotape system on a secluded, Georgia, barrier beach revealed that the ghost crab Ocypode quadrata (Fabricius) exhibits diurnal deposit-feeding behavior similar to that manifested by the sand fiddler crab Uca pugilator (Bosc).

AbstractOcypode quadrata, a Ghost crab species found along the western Atlantic coast, is considered a bioindicator of anthropogenic impact on sandy beaches. Ghost Crabbing, a touristic activity in which ghost crabs are chased just for fun, is a potentially threatening activity for this crab. In crustaceans, metabolites such as glucose and lactate, and

Recreational impacts on the distribution of ghost crabs Ocypode quadrata fab.
Biological Conservation, 1981Abstract Studies were conducted at Assateague Island, Maryland-Virginia, to determine the relative number of ghost crabs Ocypode quadrata Fab. on beaches subject to different recreational uses. The mean density of crabs per 0·1 ha plots was found to be 10 on an undisturbed beach, 19 on a pedestrian-impacted beach, 1 on a light off-road vehicle (ORV ...

Evidence of marine debris usage by the ghost crab Ocypode quadrata (Fabricius, 1787)
Marine Pollution Bulletin, 2018Sandy beaches are sites of marine debris stranding, but the interaction of beach biota with waste is poorly studied. The objective of this study was to investigate whether the ghost crab Ocypode quadrata selects marine debris by types using a non-destructive method on sandy beaches of Southeastern Brazil.

Eyestalk Movements Induced by Polarized Light in the Ghost Crab, Ocypode quadrata
Science, 1961Differential visual sensitivity to vertical and horizontal linear polarization is shown in the light-induced eyestalk deviations of Ocypode quadrata. Responses with the e -vector vertical averaged about 6° greater than those with e-vector horizontal.
