Morphological descriptions and morphometric discriminant function analysis reveal an additional four groups of spp.

There are four species of mud crabs within the genus , and most of them live sympatrically in the equatorial region. Apart from a report in Japan about the finding of a natural hybrid more than a decade ago after the division of genus into four species by Keenan, Davie & Mann (1998), no subsequent sighting was found. Thus, this study investigates the possible natural occurrence of potential hybridization among species in the wild.

Female-specific SNP markers provide insights into a WZ/ZZ sex determination system for mud crabs Scylla paramamosain, S. tranquebarica and S. serrata with a rapid method for genetic sex identification.

Background: Mud crabs, Scylla spp., are commercially important large-size marine crustaceans in the Indo-West Pacific region. As females have the higher growth rate and economic value, the production of all female stocks is extremely essential in aquaculture.

The complete mitochondrial genome of (Decapoda: Brachyura: Varunidae) and its phylogeny.

The complete mitochondrial genome plays an important role in the research on phylogenetic relationship. Here, we reported the first complete mitochondrial genome sequence of Hwang & Takeda, 1986 (Varunidae). The complete mtDNA (15,915 bp in length) consisted of 13 protein-coding genes, 22 tRNAs, two rRNA genes, and a control region.
