Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

open access: yesJournal of Anatomy, Volume 247, Issue 6, Page 1109-1130, December 2025.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Diversity and development of the hemibacula of croaking geckos (Sphaerodactylidae: Aristelliger)

open access: yesJournal of Anatomy, Volume 247, Issue 6, Page 1145-1156, December 2025.
Geckos in the genus Aristelliger exhibit enigmatic mineralized elements in their hemipenes, called hemibacula. We examined hemibacula of every species of Aristelliger using μCT, clearing and staining, and histology. We found hemibacula exhibit lineage‐specific morphology, isometric growth after sexual maturity, and are composed of mineralized ...

Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

open access: yesExperimental Physiology, Volume 110, Issue 12, Page 1917-1927, December 1, 2025.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...
