The present study was carried out to determine the Decapod Crustaceans fauna in association with Sarcotragus muscarum Schmidt, 1864 from the Levantine Sea coasts of Turkey studied between 13 September 2005 and 07 October 2005. As a result of the present study, a total of 711 specimens belonging to 12 decapod species were identified. Among the species determined, Synalpheus gambaroloides (Nardo,...

The gut of the Decapod has been known to show many differences in histological structure from that of vertebrates; i. e., the foregut and hindgut of the Decapod possess cuticular coats composed of protein ground substance with chitinous fibrils, on the luminal surface of the gut epithelium, whereas the midgut lacks it (HUXLEY, 1881). Furthermore it has been reported that the muscle fibers of th...

In the past only very few works dealt with fossil decapod crustaceans from Slovakia. The systematic research of this group has never been fully conducted there. This contribution provides a short review of all known Mesozoic and Cenozoic fossil decapod occurrences. So far, most of the taxa were described from the Eocene and Miocene strata.

Most marine invertebrate species exhibit a complex life cycle including a planktonic larval phase and a benthic juvenileadult phase. Metamorphosis and settlement are the links between these phases of development. In many species, metamorphosis is triggered by specific chemical and/or physical cues, mainly associated with the adult habitat. In the absence of such cues, competent larvae can delay...

Background. Neuropeptides are important regulators of physiological processes and behavior. Although they tend to be generally well conserved, recent results using trancriptome sequencing on decapod crustaceans give the impression of significant differences between species, raising the question whether such differences are real or artefacts. Methods. The BLAST+ program was used to find short re...

Cadmium injections induced only a single form of metallothionein (MT) in the midgut gland of Potamon potamios, whereas the same treatment induced two isoforms in Astacus astacus. The only difference between the two latter isoforms was that one had an extra N-terminal methionine residue. MT from P. potamios showed structural differences from other decapod crustacean MTs. It contained a Gly-Thr m...

Extranuclear basic proteins have been detected in the capsule of the spermatozoa of three species of decapod crustaceans (Nephrops norvegicus L., Macrura; Eupagurus bernhardus L., Anomura; Carcinus maenas Penn., Brachyura). Their properties have been studied by cytochemical methods. Their position inside the capsule of the spermatozoon has been specified with the aid of the electron microscope....
