A total of 68 species of anomuran and 284 living species of brachyuran crabs are listed as reliably occurring in the Hawaiian Islands. These figures include 12 species of brachyurans known to have been introduced, but not four species of anomurans and nine brachyurans whose identifications are questionable and two species of anomurans and 14 brachyurans that appear to have been recorded from the islands in error. Five species of anomurans and one brachyuran so far only known from the Midway Islands are included in the total number of Hawaiian species, but not five species of brachyurans only k

Abstract:

The brachyuran fauna of the large southern Philippine island of Mindanao is poorly known, with only a few freshwater and estuarine crab species described or recorded in the last 30 years. Renewed interest in crab biodiversity has led to recent, small-scale surveys (2016–2019) of freshwater and estuarine habitats in various localities in Mindanao, which have yielded a good diversity of brachyuran crabs. As a result, a total of 26 species of brachyuran crab, representing 6 families (Hymenosomatidae, Oziidae, Gecarcinidae, Sesarmidae, Varunidae, and Ocypodidae), are reported here. Of these, 15 sp

Fifty-three species were recorded during this study, of which 17 species are newly recorded from the islands, and three are also new records for India. A total of 169 species of brachyuran crabs are now known from Lakshadweep.

Abstract:

Here we report on a large brachyuran crab species from the Late Cretaceous of Mexico that has claws indicative of highly specialized shell-breaking behaviour. This crab possessed dimorphic claws (the right larger than the left), armed with several broad teeth, including a curved tooth structure found at the base of the movable finger of the right claw. The curved tooth is similar to the one observed on claws of many living durophagous crabs that use it as a weapon to peel, crush or chip the edges of hard-shelled prey, particularly molluscs. These morphological traits suggest that specialized s

Abstract:

Morphological traits have often been used to predict diet and trophic position of species across many animal groups. Variation in gut size of closely related animals is known to be a good predictor of dietary habits. Species that are more herbivorous or that persist on low-quality diets often have larger stomachs than their carnivorous counterparts. This same pattern exists in crabs and in most species, individuals exhibit external markings on the dorsal side of their carapace that appear to align with the position and size of their gut. We hypothesized that these external markings could be us

Abstract:

Three new species of the bopyrid genus Scyracepon Tattersall, 1905 are described from crabs collected on Pacific Islands: Scyracepon polynesiensis n. sp. from the Society Islands, S. pseudoliomerae n. sp. from the Mariana Islands, and S. biglobosus n. sp. from the Line Islands. The first two were found infesting Xanthias lamarckii and Pseudoliomera sp. (Xanthidae), a new host family for species of Scyracepon, and the last was found parasitizing Schizophrys aspera (Majidae). Scyracepon now includes 11 species, all but one known from single collections, infesting 12 host species in 9 brachyuran

Abstract:

Brachyuran crab carapaces are protective, impact-resistant exoskeletons with elaborate material microstructures. Though several research efforts have been made to characterise the physical, material and mechanical properties of the crab carapace, there are no studies detailing how crab morphologies might influence impact resistance. The purpose of this paper is to characterise and compare Brachyuran crab carapace morphologies in relation to their impact properties, using opto-digital, experimental and numerical methods. We find that crab carapaces with both extended carapace arc-lengths and de

A crab referable to the Necrocarcinidae Förster, 1968, is here described from the Cenomanian Bahariya Formation, Bahariya Oasis, Egypt. The occurrence of a crab in a mangrove setting in association with terrestrial vertebrates is extremely unusual in the fossil record.

The gene arrangement of G. albolineatus is similar to that of ancestral crustaceans, barring that of the translocated trnH gene.

This study aims to record brachyuran species on the west coast of Sumatra that are still unknown. Sampling was conducted in Central Tapanuli Regency and Sibolga City using convenience sampling.

The size of female functional maturity is 22-23 mm carapace width. Immature females larger than 15 mm carapace width are observed mating, usually have sperm in their seminal receptacles, and this sperm is retained through subsequent moults.

B. latro were prepared such that their branchial chambers could be perfused with artificial urine, and the rate of ion transport from the artificial urine was determined.
