Gastric evacuation of the redspotted catshark under laboratory conditions
Journal of Fish Biology, 2001An exponential model provided the best description of the gastric evacuation of the redspotted catshark Schroederichthys chilensis and predicted that 98% of a single initial meal was evacuated in 73·9 h at 16·3°C, slower than that reported for other elasmobranchs.

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 ...

AbstractWe evaluated the histology of the spiral intestine of the blackmouth catshark (Galeus melastomus), a small shark distributed in the eastern Atlantic and Mediterranean Sea basin. Entire digestive tracts of 10 G. melastomus were studied using histochemical, immunohistochemical, and ultrastructural methods.

Retinal ganglion cells (GCs) in the Japanese catshark <i>Scyliorhinus torazame</i> were labeled retrogradely with biotinylated dextran amine (BDA3000). First the labeled cells were classified into 5 morphological types (types I-III: small GCs; types IV and V: large GCs) according to the size of the soma and the dendritic arborization ...

Photo‐identification as a tool to study small‐spotted catshark Scyliorhinus canicula
Journal of Fish Biology, 2018Photo‐identification (photo‐ID) was tested as a means to identify individual small‐spotted catsharks Scyliorhinus canicula. The spotting pattern of the caudal region of S. canicula was used for the tests and revealed that photo‐ID is an efficient method to identify individuals.

Distribution and Biology of the New Zealand Endemic Catshark, Halaelurus dawsoni
Environmental Biology of Fishes, 2006Halaelurus dawsoni has a restricted geographic range, occurring only in south-eastern New Zealand. It is primarily a demersal inhabitant of the upper continental slope, plateaus, and ridges at 250–800 m depth. Halaelurus dawsoni is a voracious carnivore that feeds on a wide variety of crustaceans and fishes.
