Habitat Availability, Jurassic and Cretaceous Origins of the Deep-Bodied Shark Morphotype and the Rise of Pelagic Sharks. [PDF]
Ecol EvolWe find support for a benthic origin of sharks, with four discrete transitions towards pelagic‐type morphology occurring during the Jurassic and Cretaceous. Increased habitat availability driven by biotic and abiotic environmental change may have driven shifts towards pelagic‐type morphology. These results may help explain discordance between molecular

The Phenomenon of Piebaldism in Sharks: A Review of Global Sightings and Patterns. [PDF]
Ecol EvolChromatic disorders like piebaldism—a rare form of leucism causing partial pigment loss—have been documented in 25 wild shark cases across 17 species and 11 families, with varying anatomical distribution. This study compiles published and unpublished records to better understand the taxonomic and geographical spread of piebaldism and its potential ...

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.

Reallocation of the magnificent catshark Proscyllium magnificum Last & Vongpanich, 2004 to the genus Ctenacis Compagno, 1973 (Carcharhiniformes: Proscylliidae). [PDF]
J Fish BiolAbstract The magnificent catshark Proscyllium magnificum was described in 2004 based off five specimens collected in the Andaman Sea off Myanmar. It was originally allocated to the genus Proscyllium, but recent molecular analyses suggested it was more closely related to the harlequin catshark Ctenacis fehlmanni from the western Indian Ocean.
