Apristurus iterum, a new shark discovered based on egg case morphology and sequence data obtained from a formalin-fixed specimen. [PDF]

J Fish Biol
Abstract 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.

Application of spatially robust stereo-BRUV sampling for quantifying fish assemblages in UK marine protected areas. [PDF]

Ecol Appl
Abstract Marine protected areas (MPAs) often lack adequate data on the status of marine assemblages to support evidence‐based management. Stereo baited remote underwater video (BRUV) systems offer a powerful, low‐cost tool for collecting ecological data, yet they remain underutilized in the North East Atlantic, especially compared to more invasive ...

Reallocation of the magnificent catshark Proscyllium magnificum Last & Vongpanich, 2004 to the genus Ctenacis Compagno, 1973 (Carcharhiniformes: Proscylliidae). [PDF]

J Fish Biol
Abstract 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.

Insights Into the Ecomorphology of the Blue Shark (<i>Prionace glauca</i>) in the Adriatic Sea (Central Mediterranean Sea). [PDF]

Ecol Evol
This study examines how the morphology of Mediterranean blue sharks (Prionace glauca ) changes throughout their development. Using linear and geometric morphometrics, it reveals that juveniles and adults differ in fin and head shape, reflecting adaptations to different ecological and swimming demands.
