The Lesser-spotted Dogfish (scyliorhinus Canicula): Parasites and Scavenger Habits
The occurrence of parasites in the digestive tract of the lesser-spotted dogfish (Scyliorhinus canicula) caught in the north western Mediterranean was analysed and the results compared with infestation levels in samples of the same species caught in the Atlantic (off the south west coast of Ireland). The relationships between parasite levels and the scavenger habits of the lesser-spotted dogfis...
متن کاملSexual Dimorphisms in the Dermal Denticles of the Lesser-Spotted Catshark, Scyliorhinus canicula (Linnaeus, 1758)
The dermal layers of several elasmobranch species have been shown to be sexually dimorphic. Generally, when this occurs the females have thicker dermal layers compared to those of males. This sexual dimorphism has been suggested to occur as a response to male biting during mating. Although male biting as a copulatory behaviour in Scyliorhinus canicula has been widely speculated to occur, only r...

متن کاملSingle nephron function of the lesser spotted dogfish, Scyliorhinus canicula, and the effects of adrenaline.
Function of the kidney and the nephron in the lesser spotted dogfish, Scyliorhinus canicula, was investigated by clearance, renal tubular micropuncture and ferrocyanide infusion techniques. 70% of the glomerular filtrate was reabsorbed within the renal tubule, producing slightly hypotonic urine. Glomeruli were: perfused and filtering (F); arterially perfused but not filtering (NF); or non-arter...
متن کاملMetal accumulation and metallothionein induction in the spotted dogfish Scyliorhinus canicula.
Recent studies indicate that elasmobranch fish respond differently to metal exposure than marine teleosts. Accumulation rates can be high, which despite the fact that normal background levels for metals in the marine environment are low, is worrying due to the long life span and late fecundity of most shark. The goals of the present study were to examine differences in accumulation rates and to...
