| characterization of chitinolytic bacteria and histological aspects of shell disease syndrome in european spiny lobsters (palinurus elephas) (fabricius 1787). | the present research reports the first description of shell disease syndrome in european spiny lobsters palinurus elephas (fabricius 1787), which occurred in an experimental aquaculture facility in sicily (italy). both bacterial characterization and histopathological examination of the exoskeleton at site of lesions was carried out. infected specimens showed tail fan erosions, and in one case uropod ulceration and complete loss of periods. identified species included: listonella anguillarum 50.5 ... | 2010 | 20361978 |
| two sniffing strategies in palinurid lobsters. | most studies of lobster chemoreception have focused on the model systems of panulirus argus (palinuridae) and homarus americanus (nephropidae). we compare antennule morphology across lobsters and conduct the first kinematic study of antennule flicking in a palinurid species other than p. argus. high-speed video analysis shows that palinurus elephas flicks at a rate more than an order of magnitude higher than in p. argus. however, both species flick their antennular flagella at a reynolds number ... | 2002 | 12432011 |
| behavioural and biochemical stress responses of palinurus elephas after exposure to boat noise pollution in tank. | this study examined the effects of boat noise on the behavioural and biochemical parameters of the mediterranean spiny lobster (palinurus elephas). the experiment was conducted in a tank equipped with a video and audio recording system. 18 experimental trials, assigned to boat noise and control conditions, were performed using lobsters in single and group of 4 specimens. after a 1h habituation period, we audio- and video-recorded the lobsters for 1h. during the experimental phase, the animals as ... | 2014 | 24910186 |
| squeaking with a sliding joint: mechanics and motor control of sound production in palinurid lobsters. | the origin of arthropod sound-producing morphology typically involves modification of two translating body surfaces, such as the legs and thorax. in an unusual structural rearrangement, i show that one lineage of palinurid lobsters lost an antennal joint articulation, which transformed this joint from moving with one degree of freedom into a sliding joint with multiple degrees of freedom. with this sliding joint, 'stick-and-slip' sounds are produced by rubbing the base of each antenna against th ... | 2002 | 12124363 |
| tyrosinases from crustaceans form hexamers. | tyrosinases, which are widely distributed among animals, plants and fungi, are involved in many biologically essential functions, including pigmentation, sclerotization, primary immune response and host defence. in the present study, we present a structural and physicochemical characterization of two new tyrosinases from the crustaceans palinurus elephas (european spiny lobster) and astacus leptodactylus (freshwater crayfish). in vivo, the purified crustacean tyrosinases occur as hexamers compos ... | 2003 | 12466021 |
