The emphasis in this review will be on Na(+) absorption across the skin and gills of vertebrates and the gills of crustaceans. However, some recent studies of Cl(-) uptake, especially in crustaceans, will also be described.

The Vembanad Lake located on the south-west coast of India, an ecological hotspot is the nursing ground of many economically important crustaceans. The prevalence of white spot syndrome virus (WSSV) among crustaceans from farmed, estuarine and marine environments surrounding the Vembanad Lake, India was detected using PCR. A total of 308 samples from aquaculture ponds consisting of six species ...

The adoption of a symbiotic lifestyle is a major adaptation in the marine realm. Protection against environmental stress, escape from natural enemies, and nourishment are the major benefits obtained by symbiotic crustaceans from hosts. Hosts also represent a mating and nursery ground for symbiotic crustaceans. Costs and/or benefits experienced by hosts are diverse but may be subtle and challeng...

An arthropod phylogeny derived from nucleotide sequences (Regier et al., 2010) did not consider either the morphology or the development of crustaceans. Examples of a morphological transformation and developmental data appear to provide only limited support for the cladogram because similar morphology and development are found among distantly related crustaceans, while differing morphology and ...

Recent molecular analyses indicate that crustaceans and hexapods form a clade (Pancrustacea or Tetraconata), but relationships among its constituent lineages, including monophyly of crustaceans, are controversial. Our phylogenetic analysis of three protein-coding nuclear genes from 62 arthropods and lobopods (Onychophora and Tardigrada) demonstrates that Hexapoda is most closely related to the ...

In this study, the feeding habits of blue swimming crab (Portunus segnis) in the Northeast Persian Gulf were investigated. A total of 722 specimens were collected using bottom trawl. The samples were transferred to the laboratory in order to further analysis after freezing. All individuals were dissected and their stomach was removed. The results showed the vacancy index of stomach (CV) was 34....
