The subcomissural organ (SCO) is an ancient and conserved brain gland secreting glycoproteins into the cerebrospinal fluid which condense to form Reissner's fiber (RF). The SCO of an elasmobranch species, the dogfish Scyliorhinus canicula, was investigated applying morphological and biochemical methods.

Antioxidant efficiency and detoxification enzymes in spotted dogfish Scyliorhinus canicula
Marine Environmental Research, 2004Although elasmobranchs are widely distributed species, commonly found on sandy, gravely or muddy bottoms, several biological aspects of their metabolism still remain poorly investigated. In this work the efficiency of antioxidant system and detoxification enzymes were investigated in the coastal spotted dogfish Scyliorhinus canicula and in the red ...

The structure of the gills of the elasmobranch, Scyliorhinus canicula (L.)
Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1973The anatomy of the blood supply to the gills of the dogfish, Scyliorhinus canicula, is described. The anatomical basis for a counter-current exchange system at the respiratory surfaces is reported. Within the interbranchial septum there is a capillary network joining all the afferent branchial arterioles of the gill.

Humoral immune response of the small-spotted catshark, Scyliorhinus canicula
Fish & Shellfish Immunology, 2013Cartilaginous fishes are the oldest group in which an adaptive immune system based on immunoglobulin-superfamily members is found. This manuscript compares humoral immune function in small-spotted catshark (Scyliorhinus canicula) with that described for spiny dogfish (Squalus acanthias), another member of the Squalomorphi superorder, and nurse shark ...

[Metabolism of glucosamine in the liver of Scyliorhinus canicula (selachian)].
Archives internationales de physiologie et de biochimie, 1977(1) The metabolism of the glucosamine was studied in the liver of S. canicula, after injection of D-(1-14C) glucosamine into the animal. (2) The labelled acid-soluble derivatives were separated by ion exchange columns and characterized by chromatography and electrophoresis, and were identified as glucosamine, glucosamine 6-P, N-acetylglucosamine, N ...

The cerebellum of the dogfish, Scyliorhinus canicula: a quantitative study.
Journal fur Hirnforschung, 1987This quantitative study on neuron populations of the dogfish cerebellum reveals noticeable differences in cell size and density between its portions. A remarkable result was the large proportion of granule, Golgi and stellate cells as regards to the Purkinje cells, with some values higher than in many mammals. These results indicate that the complexity

Receptor cells in the pineal organ of the dogfish Scyliorhinus canicula linn�
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1968The pineal parenchyma of the dogfish Scyliorhinus canicula contains sensory (receptor) cells and supporting cells. The ultrastructural characteristics of these cells are described. The sensory cell is a photoreceptor-like cell the outer segment of which is, however, often irregularly developed.

Embryonic Development of the Inner Ear of the Catshark Scyliorhinus canicula
Brain, Behavior and EvolutionIntroduction: The inner ear is a complex three-dimensional structure responsible for the detection of sound, balance, and acceleration. Detailed knowledge about the development of the inner ear of gnathostomes (jawed vertebrates) comes from studies in bony fishes and tetrapods, but comparable information about this process in chondrichthyans, the ...

THE IMMUNE RESPONSE OF THE DOGFISH SCYLIORHINUS CANICULA L.
1978A number of aspects of the humoral and cellular immune responses of the common dogfish Scyliorhinus canicula L. were examined in order to define the immunological status of the animal in relation to its phylogenetic origins. The dogfish was shown to have the ability to produce specific antibody in response to a variety of soluble and particulate ...

Plastic ingestion by Scyliorhinus canicula trawl captured in the North Sea
Marine Pollution Bulletin, 2018The ingestion of plastic debris by marine organisms has been documented across a variety of taxa including; marine mammals, sea birds, sea turtles and some fish species. Fewer reports have described ingestion by sharks, in this study the gastrointestinal tracts of 20 small spotted catsharks (Scyliorhinus canicula) trawl captured in the North Sea were ...
