Angel sharks: A review of biological knowledge and exploitation

Angel sharks (Squatinidae): A review of biological knowledge and exploitation Jim R. Ellis, Joanna Barker, Sophy R. McCully Phillips, Eva K. M. Meyers, Michelle Heupel ABSTRACT: Angel sharks (Squatina spp.) are distributed in warm temperate to tropical waters around the world. Many species occur in shelf seas and exhibit seasonal inshore‐offshore migrations, moving inshore to

Cell culture-based karyotyping of orectolobiform sharks for chromosome-scale genome analysis

Cell culture-based karyotyping of orectolobiform sharks for chromosome-scale genome analysis Yoshinobu Uno, Ryo Nozu, Itsuki Kiyatake, Nobuyuki Higashiguchi, Shuji Sodeyama, Kiyomi Murakumo, Keiichi Sato, Shigehiro Kuraku ABSTRACT: Karyotyping, traditionally performed using cytogenetic techniques, is indispensable for validating genome assemblies whose sequence lengths can be scaled up to chromosome sizes using modern methods. Karyotype reports of

A new synapomorphy in the pelvic girdle reinforces a close relationship of Zanobatus and Myliobatiformes

A new synapomorphy in the pelvic girdle reinforces a close relationship of Zanobatus and Myliobatiformes (Chondrichthyes: Batoidea) João Paulo Capretz Batista da Silva, Thiago Silva Loboda, Ricardo de Souza Rosa ABSTRACT: The rays of the order Myliobatiformes present several diagnostic characters, the most striking one being the presence of a serrated sting on the dorsal

The current knowledge gap on metallothionein mediated metal-detoxification in Elasmobranchs

The current knowledge gap on metallothionein mediated metal-detoxification in Elasmobranchs

The current knowledge gap on metallothionein mediated metal-detoxification in Elasmobranchs Rachel Ann Hauser-Davis​ ABSTRACT: Elasmobranchs are particularly vulnerable to environmental contamination, especially pollutants that may bioaccumulate and biomagnify, throughout the trophic web, such as metals. However, Elasmobranch management and conservation plans are challenging, and this group is often neglected regarding ecotoxicological analyses, particularly concerning metal
