Characterization of the complete mitochondrial genome of blacktip shark Carcharhinus limbatus (Carcharhiniformes: Carcharhinidae) [PDF]
Mitochondrial DNA. Part B. Resources, 2022 In this study, we aimed to determine the complete mitochondrial genome of blacktip shark Carcharhinus limbatus. The mitochondrial genome was 16,705 bp in length, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region ...

Apristurus iterum, a new shark discovered based on egg case morphology and sequence data obtained from a formalin-fixed specimen. [PDF]
J Fish BiolAbstract Apristurus iterum, a new species of deepwater catshark, is described from northeastern Australia. The new species is diagnosed through examination of its unique egg case morphology based on a single whole gravid female specimen and 10 egg cases deposited in different Australian ichthyological collections.

Three-dimensional fossils of a Cretaceous collared carpet shark (Parascylliidae, Orectolobiformes) shed light on skeletal evolution in galeomorphs [PDF]
Royal Society Open ScienceA rich fossil record of teeth shows that many living shark families’ origins lie deep in the Mesozoic. Skeletal fossils of the sharks to whom these teeth belonged are far rarer and when they are preserved are often flattened, hindering understanding of ...
