Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988 [PDF]
The Anatomical Record, Volume 309, Issue 10, Page 2897-2912, October 2026.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Range extension and first records of Coryphaenoides striaturus Barnard, 1925 and Coryphaenoides subserrulatus Makushok, 1976 (Macrouridae: Gadiformes) in Brazilian waters, Southwest Atlantic, using integrative taxonomy [PDF]
Journal of Fish Biology, Volume 109, Issue 1, Page 599-604, July 2026.Abstract Coryphaenoides Gunnerus, 1765 comprises 66 valid species of deep‐sea fishes commonly known as grenadiers, with 6 previously reported from Brazilian waters. Here, we make the first records for Coryphaenoides striaturus and Coryphaenoides subserrulatus on the Brazilian continental slope. Both species are distributed in the subtropical regions of

Evidence of a Potential Nursery Area for the Great Hammerhead Shark, Sphyrna mokarran, in the Largest Coral Reef System of the Southwestern Atlantic [PDF]
Ecology and Evolution, Volume 16, Issue 8, August 2026.We present evidence suggesting that the Abrolhos Bank functions as key habitat for early life stages of Sphyrna mokarran. Kernel density estimation revealed spatially structured aggregations, with neonates and young‐of‐the‐year concentrated in shallow reef‐associated areas. Temporal variation in catch per unit effort (CPUE) indicated recruitment pulses

A new Hyphessobrycon (Characiformes: Acestrorhamphidae) of the Hyphessobrycon agulha lineage of Hyphessobryconinae from the lower Aripuanã basin, Brazil, with comments about the lineage [PDF]
Journal of Fish Biology, Volume 109, Issue 1, Page 58-69, July 2026.Abstract A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru [PDF]
Journal of Fish Biology, Volume 109, Issue 1, Page 102-110, July 2026.Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary
