Cartilaginous fishes are a highly vulnerable vertebrate group but remain poorly studied, especially those occupying deep-water ecological niches. Here, we describe the complete mitogenome of the deep-water chimaeriform Hydrolagus affinis (de Brito ...

Bioenergetic Model of the Highly Exploited Shark Mustelus schmitti under a Global Warming Context
Bioenergetic models are tools that allow the evaluation of the effect of environmental variables on fish growth. Successful implementation of this approach has been achieved in a few elasmobranch species. Our objective was to develop a bioenergetic model

Mechanisms and Drivers for the Establishment of Life Cycle Complexity in Myxozoan Parasites
It is assumed that complex life cycles in cnidarian parasites belonging to the Myxozoa result from incorporation of vertebrates into simple life cycles exploiting aquatic invertebrates.

Multiple paternity and hybridization in two smooth-hound sharks [PDF]
Multiple paternity appears to be a common trait of elasmobranch mating systems, with its occurrence likely driven by convenience, due to females seeking to minimize the stress of male harassment.

The Synarcual of the Little Skate, Leucoraja erinacea: Novel Development Among the Vertebrates
Evolutionary variation in anteroposterior patterning of the axial skeleton is a major contributor to the evolution of the vertebrate body plan, with five canonical vertebral types in tetrapods (cervical, thoracic, lumbar, sacral, caudal).

Chondrichthyans (sharks, rays and chimeras) are a fascinating and highly vulnerable group of early branching gnathostomes. However, they remain comparatively poorly sampled from the point of view of molecular resources, with deep water taxa being ...

We describe a microvertebrate assemblage from the J&M site, of the Upper Cretaceous (Campanian–Maastrichtian) Williams Fork Formation. Breakdown of fossil bearing matrix was achieved with the use of heated dimethyl sulfoxide.

Sharks, Rays and a Chimaeroid from the Kimmeridgian (Late Jurassic) of Ringstead, Southern England [PDF]
Sampling of a lenticular concentration of vertebrate debris and associated sediments from the lower Kimmeridgian of southern England has allowed the study of a diverse and abundant assemblage of chondrichthyan remains.

Barremian and Aptian (Cretaceous) sharks and rays from Speeton, Yorkshire, north-east England [PDF]
Bulk sampling of a number of horizons within the upper part of the Speeton Clay Type section has produced teeth and other remains of sharks and rays from several poorly studied horizons.
