Many freshwater shrimps (Decapoda, Caridea) have amphidromous life histories, with extended planktonic larval development in the sea. Larvae either are hatched upstream to drift down to the sea or are carried and released there by females. After development, postlarvae (juveniles) must migrate back up to their adult freshwater habitat. An amphidromous life cycle thus involves long distance migr...

The chola guitarfish, Rhinobatos percellens, is one of the most-captured batoids on the Brazilian coast, and an important predator of benthic community. Stomachs from R. percellens were sampled in the Paranaguá estuarine complex (March/2006 to March/2007 and October/2008 to September/2009). The stomachs obtained were used for describing the diet of R. percellens, and verifying if there are seas...

The present paper reports two new species of Glyphocrangon (Crustacea, Caridea, Glyphocrangonidae) collected respectively from the East China Sea and the Philippines. G. singularis sp. nov., from the East China Sea, is similar to G. fimbriata Komai & Takeuchi, 1994 with the presence of fringe of setae on dactyl of the third to fifth pereopods, but differs from G. fimbriata by the rostrum shape ...

The palaemonid shrimp genus Palaemonella Dana, 1852 is currently represented by 21 formally described species worldwide, of which 17 species are known from the Indo-West Pacific. In this study, a new species, P. okunoi, is described and illustrated on the basis of two ovigerous female specimens collected from coastal waters in Okinawa Island, Ryukyu Islands, Japan, at depths of 5-30 m. The new ...

The atyid genus Micratya Bouvier, 1913 was previously considered to be monotypic. The area in which the genus is dis-tributed is limited to the islands of the Antilles and Central America, with the type locality of Micratya poeyi being in Cuba. A recent molecular phylogenetic analysis of atyid shrimps from the Caribbean indicated the probable existence of a second species of Micratya from sampl...

A third species of the pontoniine shrimp genus Eupontonia Bruce, 1971, E. gracilipes n. sp., is described and illustrated on the basis of a single female specimen collected from shallow water of Ishigaki Island, southern Ryukyu Islands, Japan. The new species is readily distinguished from the two congeneric species, E. noctalbata Bruce, 1971 and E. oahu Bruce, 2010, by a number of morphological...
