... lineage, show a conspicuous, well-organized cerebellar nucleus, unlike ray-finned fishes. To gain insight into the evolution and development of the cerebellar nucleus, we analyzed in the shark Scyliorhinus canicula (a chondrichthyan model species) the developmental expression of several genes coding...

... must maximise light absorption in order to enhance the detection of prey, predators and potential mates. Using stereological analysis of retinal wholemounts, the distribution and number of photoreceptors (rods) was determined for 5 deep-sea shark species from a range of depths (46-1,500 m). All species...

... stages of the evolution of jawed vertebrates, this group also covers a diverse range of eco-morphotypes, occupying both marine and freshwater habitats. The class Chondrichthyes is divided into two subclasses: the Elasmobranchii (sharks, skates, and rays) and the Holocephali (elephant sharks and chimaeras...

...L.I. Crawshaw; H.T. Hammel Young horn sharks ( Heterodontus francisci) were placed in an apparatus where they could choose between two chambers whose water temperatures differed by 10 °C. When the warmer chamber was at 26 °C, the sharks spent more time in the 26 °C water when the brain stem...

...Malcolm F. MacDonnell In 22 adult sharks representing eight species, the mesencephalic trigeminal nucleus (Mes V) was examined employing the Romanes reduced silver method. Morphological evidence is presented of extensive development of neurites and intranuclear communication among Mes V cells...

...Malcolm F. MacDonnell The midline ridge formation (MRF) of the trigeminal complex in 127 cartilaginous fish of 15 species was examined by scanning electron microscopy or light microscopy. Five distinct species variations of the MRF in sharks are described. The formation has not yet been observed...
