Placoid scales in bioluminescent sharks: Scaling their evolution using morphology and elemental composition [PDF]
, 2022 Elasmobranchs are characterised by the presence of placoid scales on their skin. These scales, structurally homologous to gnathostome teeth, are thought to have various ecological functions related to drag reduction, predator defense or abrasion ...

Predicting time‐at‐depth weighted biodiversity patterns for sharks of the North Pacific
Ecography, Volume 2025, Issue 3, March 2025.Depth is a fundamental and universal driver of ocean biogeography but it is unclear how the biodiversity patterns of larger, more mobile organisms change as a function of depth. Here, we developed a predictive biogeography model to explore how information of mobile species' depth preferences influence biodiversity patterns.

Whalesuckers and a spinner dolphin bonded for weeks: does host fidelity pay off? [PDF]
, 2015 The whalesucker Remora australis (Echeneidae) is an oceanic diskfish found attached to cetaceans only and its habits are therefore poorly known. At the Fernando de Noronha Archipelago, off North-eastern Brazil, spinner dolphins Stenella longirostris ...

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change
Global Change Biology, Volume 30, Issue 7, July 2024.This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...

Illuminating the evolution of bioluminescence in sharks [PDF]
, 2023 The evolutionary context in which shark bioluminescence originated is poorly understood, despite it being critical to uncovering influential factors in the evolutionary history and diversity of living chondrichthyans as well as the mechanisms of deep ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 5, Page 499-508, June 2024.Abstract Biopsy has recently become a preferred protocol for sampling the skin and blubber of many cetacean species, although it is desirable to collect as minimally invasive as possible. Here, the effect of biopsy sampling on the captive common bottlenose dolphins was evaluated by analyzing the process of wound healing and changes in hematological and
