Journal of Anatomy, Volume 247, Issue 6, Page 1224-1240, December 2025.This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 11, November 2025.ABSTRACT The widenose guitarfish (Glaucostegus obtusus) is a Critically Endangered shark‐like ray in the Northern Indian Ocean. They aggregate in shallow waters where they may be threatened by nearshore fisheries, tourism and coastal development, yet their use of these spaces is not well documented. Understanding their population sizes and seasonal use

Impact of Tusk Anomalies on the Long‐Term Foraging Ecology of Narwhals
Ecology and Evolution, Volume 15, Issue 11, November 2025.We combined stable δ13C and δ15N isotope analysis and genetic sexing to investigate whether narwhals with dental anomalies have a distinct long‐term foraging ecology. Our results showed no difference in stable isotope signature of two‐tusked male and one‐tusked female narwhals relative to normal‐tusked narwhals, indicating that an extra tusk does not ...

Ecology and Evolution, Volume 15, Issue 11, November 2025.We present the first species‐specific epigenetic clock for common dolphins (Delphinus delphis), calibrated using dental ages from stranded and bycaught individuals. Despite concerns about dental ageing accuracy, our models showed strong performance and were unaffected by decomposition, supporting the use of post‐mortem samples for epigenetic clock ...
