A Catshark (Neoselachii, Carcharhiniformes, Scyliorhinidae) From the Late Jurassic of Germany
Palaontologische Zeitschrift, 2005A new genus and species of catshark (Neoselachii, Carcharhiniformes, Scyliorhinidae) —Bavariscyllium tischlingeri n. gen. n. sp. — is described from the Late Jurassic (Tithonian) Plattenkalke of South Germany. The new taxon is known from a single articulated skeleton having the skull, the trunk and all of the fins preserved.

AbstractThe presence of claspers is one of the main characteristics of the cartilaginous fishes, but its variations across taxa have received limited use in shark systematics and have generally been neglected in descriptions of species. Clasper descriptions are available only for a few catshark species and most of these are focused only in external ...

The catshark genus Scyliorhinus belongs to the family Scyliorhinidae, the most diverse family of sharks, and currently presents 16 valid species according to most modern accounts. The long history of taxonomic rearrangements and inaccurate descriptions of many species have contributed to misidentification of specimens and lack of information on the ...

Sharks of the genus Cephaloscyllium from Taiwan were reviewed. After extensive survey of the specimens deposited in museums, universities and fisheries institutions in Taiwan and Japan, the following four species were recognized as valid in Taiwanese waters: C. umbratile Jordan & Fowler, 1903, C. fasciatum Chan, 1966, C.

The genus Apristurus has been divided formerly into three species subgroups based on morphological and molecular phylogenies. Previous studies have agreed on the separation into distinct species groups, the largest two of which have been described as the brunneus and spongiceps groups.

Mechanics of ventilation in swellsharks, Cephaloscyllium ventriosum (Scyliorhinidae)
Journal of Experimental Biology, 1999ABSTRACT A simple two-pump model has served to describe the mechanics of ventilation in cartilaginous and bony fishes since the pioneering work of G. M. Hughes. A hallmark of this model is that water flow over the gills is continuous. Studies of feeding kinematics in the swellshark Cephaloscyllium ventriosum, however, suggested that a ...

Galeus arae is currently classified as a complex of three subspecies (Galeus arae arae, Galeus arae antillensis, and Galeus arae cadenati). Morphometric and meristic analyses, size at maturity, and variation in color patterns, support the recognition of these taxa as distinct species. All species have well-developed nidamental glands and are oviparous.
