The shape of the secondary sexual characters is, traditionally, used to discriminate marine shrimps at species level. However, qualitative evaluation structures that are morphologically variable in taxonomy can favor misunderstandings and misidentifications. These possibilities taxonomic inaccuracies especially alarming when there is a need evaluate invasion introduced species. present study ge...

A new genus and species of procaridid shrimp, Vetericaris chaceorum, and a new atyid species, Halocaridina palahemo, are described from the island of Hawaii. The new genus, regarded as more primitive than Procaris, is characterized by the possession of a larger number of gills than Procaris, including arthrobranchs and pleurobranchs on the third maxilliped and pereiopods 1-4, elongate pleopodal...

The shrimp Mirocaris fortunata is a hydrothermal vent species that is found at most vent-sites along the Mid-Atlantic Ridge. This endemic species is found across a hydrothermal gradient, with thermal conditions ranging from 2-9 degrees C in ambient seawater to fairly warm values of about 25 degrees C. We performed in vivo experiments on M. fortunata specimens originating from different sites an...

BACKGROUND Whole mitochondrial DNA is being increasingly utilized for comparative genomic and phylogenetic studies at deep and shallow evolutionary levels for a range of taxonomic groups. Although mitogenome sequences are deposited at an increasing rate into public databases, their taxonomic representation is unequal across major taxonomic groups. In the case of decapod crustaceans, several inf...

Acute hepatopancreatic necrosis disease (AHPND), also known as early mortality syndrome (EMS), causes high mortalities in cultured shrimps in Asia (L. Tran et al., Dis. Aquat. Organ. 105:45-55, 2013, http://dx.doi.org/10.3354/dao02621). Here, we report the draft genome sequence of one Mexican strain of Vibrio parahaemolyticus that causes similar clinical signs in diseased shrimps.
