چکیده

We have determined the complete nucleotide sequence of the mitochondrial DNA (mtDNA) of the dogfish, Scyliorhinus canicula. The 16,697-bp-long mtDNA possesses a gene organization identical to that of the Osteichthyes, but different from that of the sea lamprey Petromyzon marinus. The main features of the mtDNA of osteichthyans were thus established in the common ancestor to chondrichthyans and osteichthyans. The phylogenetic analysis confirms that the Chondrichthyes are the sister group of the Osteichthyes.

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...

Anatomy and development of the sinoatrial valves in the dogfish (Scyliorhinus canicula).

BACKGROUND We describe the adult anatomy and the development of the cardiac sinoatrial valves in the dogfish (Scyliorhinus canicula). METHODS We use scanning electron microscopy, histological and histochemical techniques in 39 hearts from embryos and adult specimens. RESULTS The sinoatrial valvular set of the adult dogfish is composed of two transverse valves laterally attached to the sinoa...

Studies on the purification of gonadotrophin from dogfish ( Scyliorhinus canicula L . ) pituitary glands

While it is now widely accepted that two gonadotrophins, resembling mammalian LH and FSH, are produced by the pituitaries of birds, reptiles and amphibians, most work with bony fishes suggests the presence of only one gonadotrophin in this class of vertebrates (e. g. Burzawa-G6rQrd, 1971 ; Donaldson et al., 1972 ; BurzawaG6rard et al.,1975 ; Breton et al., 1976). This conclusion is, however, be...

Metal 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...
