Description of the Early Development of Hoplias intermedius (Günther, 1864) (Characiformes: Erythrinidae). [PDF]
This study provides the first description of the early development of Hoplias intermedius (Characiformes: Erythrinidae), from the embryonic to the juvenile stage. The morphological, meristic, and morphometric characterization contributes to understanding the ontogeny and developmental transitions of Neotropical fishes, supporting taxonomy, conservation,

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru. [PDF]
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

A bristle-nosed Jurassic ray-finned fish (Actinopterygii) bears true dermal odontodes on its snout. [PDF]
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison
