Early Biogeography of Otophysi Points to the Neotropics as the Cradle of Characiphysan Fishes [PDF]

Ecology and Evolution
Freshwaters represent less than 1% of Earth's surface and only 0.02% of the available aquatic habitable volume, yet they host nearly half of the 35,500 known species of bony fishes.

Genomic Insights Into Carnivorous Fish in the Characiformes [PDF]

Ecology and Evolution
The Characiformes exhibit remarkable dietary diversity, with carnivorous species displaying unique adaptations to high‐protein and high‐fat diets. However, the molecular mechanisms underlying this carnivorous specialization remain poorly understood.

On a remarkable sexual dimorphic trait in the Characiformes related to the olfactory organ and description of a new miniature species of Tyttobrycon Géry (Characiformes: Characidae)

PLoS ONE, 2019
Among the order Characiformes, secondary sexual dimorphism is commonly associated to the occurrence of bony hooks on fins, shape and length of the dorsal and anal fins, and sexual dichromatism.
