Evolutionary History of True Crabs (Crustacea: Decapoda: Brachyura) and . . . Abstract Crabs of the infra-order Brachyura are one of the most diverse groups of crustaceans with approximately 7,000 described species in 98 families, occurring in marine, freshwater, and terrestrial habitats The relationships among the brachyuran families are poorly understood due to the high morphological complexity of the group Here, we reconstruct the most comprehensive phylogeny of
Brachyura - an overview | ScienceDirect Topics In brachyuran crabs, the epithelium of posterior gills is composed by a monolayer of cells sat on the cuticle in each side of the ion-transporting gill lamella, where aggregates of ionocytes can be found
SYSTEMA BRACHYURORUM: PART I. AN ANNOTATED CHECKLIST OF EXTANT . . . ABSTRACT – An annotated checklist of the extant brachyuran crabs of the world is presented for the first time Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies Nomenclatural and taxonomic problems are reviewed in detail, and many resolved
Crab Animal Facts - Brachyura - A-Z Animals Brachyuran body plan: broad, flattened carapace with a strongly reduced abdomen folded (tucked) under the thorax; abdomen shape differs by sex (see dimorphism) Eyes on movable stalks; antennae antennules present but often less visually prominent than in some other crustaceans

Larval dispersal of Brachyura in one of the largest estuarine marine . . . All brachyuran larvae in the aliquots were dissected and identified to the lowest taxonomic level possible [1, 45 – 61] by observing the morphological parameters, such as the arrangement and number of spines and setae in the antennae, antennules, maxilliped, maxilla, abdomen, and telson, under an Axioscope Zeiss A1 optical microscope (Carl
ECOLOGY OF BRACHYURA - Brill Freshwater brachyurans Yeo et al (2008) reported 1476 species of freshwater brachyuran crabs, with represen-tatives from all zoogeographic regions except Antarctica The actual diversity of freshwa-ter brachyurans is expected to be much higher because study of the diversity, taxonomy, and ecology of the group is still in its infancy, with the bulk of the species still unde-scribed The
