Molecular phylogenetics of swimming crabs (Portunoidea Rafinesque, 1815) supports a revised family-level classification and suggests a single derived origin of symbiotic taxa [PDF]

PeerJ, 2018
Portunoidea is a diverse lineage of ecologically and economically important marine crabs comprising 8 families and 14 subfamilies. Closely related portunid subfamilies Caphyrinae and Thalamitinae constitute some of this group’s greatest morphological and

Morphology of the first zoeal stages of five species of the portunid genus Callinectes (Decapoda, Brachyura) hatched at the laboratory

Anais da Academia Brasileira de Ciências, 2014
The genus Callinectes Stimpson, 1860 currently consists of 16 species, six of which are reported in Brazilian coast. In the present study, the first zoeal stages of Callinectes bocourti,C. danae, C. exasperatus, C. ornatus and C. sapidus from Brazil were

DNA barcoding allows identification of undescribed crab megalopas from the open sea

Scientific Reports, 2021
Megalopas of 15 brachyuran crab species collected in the open sea plankton, and unknown until now, were identified using DNA barcodes (COI and 16S rRNA). Specimens belonging to the families Portunidae, Pseudorhombilidae and Xanthidae (Crustacea, Decapoda,

Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

Acta Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab 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 ...

Relative Growth and Size Structure of Achelous spinicarpus Stimpson, 1871 Associated with Shrimp Trawling in the State of Veracruz

Journal of Marine Science and Engineering, 2021
The objective was to analyse the relative growth and size structure of Achelous spinicarpus associated with trawling in Veracruz. The organisms came from shrimp trawls carried out in July 2013. There were 45 trawls organized in two depth intervals (B: 22

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
