Ontogenesis of digestive system inLitopenaeus vannamei(Boone, 1931) (Crustacea: Decapoda)

Ontogenesis and functional morphology of the digestive system of the freshwater prawn, Macrobrachium amazonicum (Decapoda: Palaemonidae)

The appropriate feeding regime for larvae and post-larvae of crustacean decapods is essential for successful larval culture. Reports on the development and morphology of the mouthparts and foregut of these crustaceans have aided in the selection of appropriate larval foodstuffs and consequently increased larval survival and growth rate during development. In the present study, the functional mo...

Morphology and histology of P. argentinus (Crustacea, Decapoda, Caridea) digestive tract.

This work describes the morphology and histology of the P. argentinus digestive tract. The foregut comprises the mouth, oesophagus, and stomach and is lined by a simple cylindrical epithelium overlain by cuticle. There are tegumental glands in the oral region and in the first portion of the oesophagus and of the hindgut. The cardiac stomach is an oval dorsal sac in the cephalothorax and has no ...

Periclimenaeus species (Crustacea: Decapoda: Pontoniinae) from Hawaii.

Two specimens of an undescribed species of pontoniine shrimp of the genus Periclimenaeus Borradaile 1915 from Maui Island, Hawaiian Islands, are described and illustrated, raising to three the number of species known from the Hawaiian Islands. The new species is remarkable for the greatly reduced molar process and sharp lateral cutting edge on the major second pereiopod dactyl and most closely ...
