Hyperostosis in Fishes: An Update With New Species Records

open access: yesJournal of Morphology, Volume 285, Issue 11, November 2024.
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

Evolution of rhodopsin in flatfishes (Pleuronectiformes) is associated with depth and migratory behavior

open access: yesJournal of Fish Biology, Volume 105, Issue 3, Page 779-790, September 2024.
Abstract Visual signals are involved in many fitness‐related tasks and are therefore essential for survival in many species. Aquatic organisms are ideal systems to study visual evolution, as the high diversity of spectral properties in aquatic environments generates great potential for adaptation to different light conditions.

Species Identification of Totoaba (Totoaba macdonaldi) From Swim Bladders by Real‐Time Fluorescence‐Based Recombinase‐Aided Amplification

open access: yesJournal of Marine Sciences, Volume 2024, Issue 1, 2024.
The increased illegal fishing to supply swim bladders is the current threat to the Totoaba macdonaldi, due to the high commercial value of swim bladders. Species identification is the foundation of the endangered animal protection. Limited by the sophisticated thermal cycling, specialized machine, and sequencing costs, DNA barcoding might not better ...
