Ghost fishing efficiency in swimming crab (Portunus trituberculatus) pot fishery [PDF]
Marine Pollution BulletinAbandoned, lost, or otherwise discarded fishing gear (ALDFG) is a global challenge that negatively affects marine environment through plastic pollution and continued capture of marine animals, so-called "ghost fishing". In different pot fisheries, ghost fishing related to ALDFG is of concern, including pot fishery targeting swimming crab (Portunus ...

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab <i>Achelous monspeliensis</i> From Portugal. [PDF]
Ecol EvolCrab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...

X-band crab cavities for the CLIC beam delivery system [PDF]
, 2008 The CLIC machine incorporates a 20 mrad crossing angle at the IP to aid the extraction of spent beams. In order to recover the luminosity lost through the crossing angle a crab cavity is proposed to rotate the bunches prior to collision.

Urbanization driving Ocypode quadrata burrow density, depth, and width across Caribbean beaches
Ecological Indicators, 2023 Globally, sandy beaches support local economies and are the most commonly-used type of coastline. This importance is perhaps most striking in the Caribbean; however, no study has assessed the morphological features of the U.S. Virgin Islands (USVI) sandy

Natural diet of Ocypode quadrata (Fabricius, 1787) (Crustacea, Decapoda, Brachyura) from the Northern Coast of São Paulo, Brazil [PDF]
Papéis Avulsos de Zoologia, 2019 Decapod crustaceans have a wide variety of feeding habits, alternating among herbivory, predation, saprophagy, and filtration. The occupation of various trophic positions in the food web is a key feature in the evolution of the group.

Hemolymph supply to locomotor muscles of the ghost crab Ocypode quadrata [PDF]
Journal of Experimental Biology, 2021 ABSTRACT Ghost crabs are the fastest and most aerobically fit of the land crabs. The exceptional locomotory capacity of these invertebrate athletes seemingly depends upon effective coupling between the cardiovascular system and skeletal muscles, but how these systems are integrated has not been well defined.
