Crustacea, particularly Decapoda, contains many economically important species, such as shrimps and crabs. Crustaceans exhibit enormous (nearly 500-fold) variability in genome size. However, limited genome resources are available for investigating these species. Exopalaemoncarinicauda Holthuis, an economical caridean shrimp, is a potential ideal experimental animal for research on crustaceans. ...

Soft tissues of species of marine fauna; crabs (Crustacea), oysters (Pelecypoda, Bivalvia), sea stars (Asterroidea), sea urchin (Echinoidea) and bony fishes (Osteichtyes) sampled along the Kenya-Mombasa coastal region were analyzed to determine the levels of organochlorine pesticides (OCPs). Analysis was done using gas chromatography with an electron capture detector. This study showed that mar...

Pycnotarsobrentus inuiae Maruyama & Bartolozzi, gen. nov. and sp. nov. (Brentinae: Eremoxenini) is described from the Lambir Hills National Park, Borneo (Sarawak, Malaysia) based on specimens collected from Crematogaster difformis F. Smith, 1857 ant nests in the myrmecophytic epiphytic ferns Platycerium crustacea Copel. and Lecanopteris ridleyi H. Christ. A second species of Pycnotarsobrentus i...

Muscle and other tissues of marine invertebrates are very dilute with respect to inorganic ions, but are nevertheless in osmotic equilibrium with the blood, in which ionic concentrations are nearly the same as in sea water (1). It has been postulated, therefore, that these tissues contain relatively high concentrations of small organic molecules (l), and it is of interest in this connection tha...

IT is well known that colour changes of animals may be brought about by (a) direct action of light, heat and other stimuli on the skin chromatophores, as, for example, in the "primary" photic response of Amphibia, and (b) action of stimuli on localized receptors. Co-ordinated responses, i.e. responses of the second type, fall into two categories which offer a striking initial contrast in their ...

Zooplankton plays key roles in structuring interactions in aquatic communities but often remain undescribed in many water systems. This paper reports seventeen species of the Cladocera (Crustacea: Branchiopoda) from Laguna de Navío Quebrado, all of them new records for La Guajira Department, Colombia. The Cladocera assemblages include mostly the Neotropical taxa associated with vegetation. This...

The first complete re-description of mud-dwelling axiid Leonardsaxius amurensis (Kobjakova, 1937) (Crustacea: Decapoda: Axiidea) is presented based on the holotype and freshly collected specimens from Vostok Bay, Russia coast of the Sea of Japan. The species is mostly morphologically similar to Leonardsaxius spinulicauda (Rathbun, 1902) known from Pacific coasts of North America from Vancouver ...
