Global status and research priorities for rhino rays

Endangered Species Research
Global biodiversity continues to decline in the terrestrial and aquatic realms. Across animal groups, threatened species are at risk of extinction if not managed effectively and permitted to recover.

Complete Mitogenome of the Russian Sturgeon Acipenser gueldenstaedtii (Acipenseriformes; Acipenseridae) [PDF]

Fisheries and aquatic sciences, 2009
Sturgeons and paddlefishes are frequently referred to as 'living fossils' among the actionpterygian lineage. They are increasingly facing threats to their existence because of various anthropogenic pressures. In this study, we present the complete mitogenome sequence of the Russian sturgeon Acipenser gueldenstaedtii (Acipenseriformes; Acipenseridae ...

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

Journal 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.

Toward a Phylogenetic Taxonomy of Sturgeons (Acipenseriformes: Acipenseridae)

Bulletin of the Peabody Museum of Natural History
Acipenseriformes, comprising sturgeons and paddlefishes, is one of the three ancient and species-poor living lineages of non-teleost Actinopterygii. Here, we use DNA sequence and morphological data to investigate the phylogenetic relationships of sturgeons and produce a phylogenetic basis for the taxonomy of Acipenseridae.

Patterns and Processes of Genomic Evolution Inferred From the Ten Smallest Vertebrate Genomes

Advanced Science, Volume 12, Issue 38, October 13, 2025.
By integrating phylogenetic relationships derived from nuclear DNA with population genetic analyses across ten pufferfish species, the genetic differentiation mechanisms underpinning the radiative speciation of the most compact vertebrate genomes has elucidated.

Development of DNA identification for sturgeon species with the use of real time polymerase chain reaction

Ribogospodarsʹka Nauka Ukraïni, 2017
Purpose. Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. Four species may now be extinct.

Subgenome Partitioning and Polyploid Genome Evolution in the Loach Family Botiidae (Order Cypriniformes)

Advanced Science, Volume 12, Issue 36, September 25, 2025.
This study investigates subgenome evolution and polyploidy in Cypriniformes fish, revealing complex phylogenetic relationships and genomic dynamics. By applying advanced subgenome partitioning methods, it uncovers novel insights into transposon activity and gene fractionation.

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou

Ecology and Evolution, Volume 15, Issue 9, September 2025.
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

Journal of Anatomy, Volume 247, Issue 3-4, Page 418-441, September/October 2025.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.
