Odorant-binding proteins (OBPs) are thought to be responsible for the transport of semiochemicals across hydrophobic interfaces to olfactory receptors. In insects, a second class of OBPs with four conserved cysteines has been variously named as sensory appendage proteins, olfactory segment-D proteins, and chemosensory proteins (CSPs). The physiological functions of these proteins have remained ...

Many Crustacea are characterized by the use of their appendages for swimming and feeding. In the lower Crustacea both the thoracic and abdominal appendages move for these purposes in a typical metachronal rhythm. The similar rhythmical movements found in the abdominal appendages of the crayfish (Hughes & Hickey, in preparation) are most probably based on similar nervous mechanisms, but here the...

> Abstract The structure of the outer parts of the maxillae and post-maxillary limbs is compared across the major crustacean groups. New anatomical observations are presented on the musculature of selected limbs of key taxa and general patterns in limb structure for the Crustacea are discussed. Exopodites vary in form but are typically provided with musculature, whereas epipodites and other exi...

Within the international IceAGE project (Icelandic marine Animals: Genetics and Ecology) some leucothoid amphipods (Crustacea) were collected, among them a rather small new species, belonging to the "Leucothoe spinicarpa-clade."

the family porcellanidae is a group of crab-shaped anomurans and there are a series of studies on this group in the persian gulf. the first report of porcellanid crabs from the persian gulf was by heller (1861); who referred incidentally to two species of this group in a discussion of crustacea of the red sea.

The complete sequence of the mitochondrial genome of the giant tiger prawn, Penaeus monodon (Arthropoda, Crustacea, Malacostraca), is presented. The gene content and gene order are identical to those observed in Drosophila yakuba. The overall AT composition is lower than that observed in the known insect mitochondrial genomes, but higher than that observed in the other two crustaceans for which...

The present study aimed to establish spatiotemporal food and feeding habits of the crab Pachygrapsus marmoratus inhabiting rocky shores southern Mediterranean Sea coast, exemplified by Al-Haniyah, Al-Hamamah, Susah sites in eastern Libya, relate them morphometric traits, abundance organisms habitat. A total 425 crabs collected during 2019 were used study. minimum maxim carapace length (CL), wei...

A new genus and species of sponge-associated pontoniine shrimps (Crustacea: Decapoda: Palaemonidae: Pontoniinae) is described from northern part of Formosa Island (Taiwan). The new species can be clearly recognized by convex robust nail-like apices on dactyli of both pereiopods II--a unique morphological structure among pontoniine shrimps. Morphological differences from all known sponge-associa...
