Caribbean spiny lobsters ( Panulirus argus ) rely on their sense of olfaction for many behaviours. Growth of their olfactory systems, and maintenance of olfactory function, is ensured by structural change that occurs continuously throughout life. In this paper, we review recent studies on postembryonic development in the olfactory system of P . argus and several other decapod species. Major str...

Under circumstances in which area for settlement is limited, the colonization of living substrata may become a highly valuable strategy for survival of marine invertebrates. This phenomenon, termed epibiosis, results in spatially close associations between two or more living organisms. Pelamis platurus, the yellow-bellied sea snake, is the only exclusively pelagic marine snake and its propensit...

The properties of acetylcholine-activated excitatory currents on the gml muscle of three marine decapod crustaceans, the spiny lobsters Panuhrus argus and interruptus, and the crab Cancer borealis, were examined using either noise analysis, analysis of synaptic current decays, or analysis of the voltage dependence of ionophoretically activated cholinergic conductance increases . The apparent me...

Decapod crustaceans synthesize highly active proteolytic enzymes in the midgut gland and release at least a part of them into the stomach where they facilitate the first step in peptide hydrolysis. The most common proteinases in the gastric fluid characterized so far are serine proteinases, that is, trypsin and chymotrypsin. These enzymes show highest activities at neutral or slightly alkaline ...

This study was carried out to determine the temporal and spatial distribution of Liocarcinus depurator (Crustacea: Decapod) caught by beam trawl in southeast Black Sea between December 2012 November 2013. Sampling executed at depths from shoreline deeper 30 m using a 2 wide İyidere, Merkez Çayeli stations. L. determined most intensely (1000 m2) 0-5 depth station during summer season. started mi...
