Genomic Insights Into Carnivorous Fish in the Characiformes [PDF]

open access: yesEcology 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)

open access: yesPLoS 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.

Characterization of the complete mitochondrial genome of Hyphessobrycon herbertaxelrodi (Characiformes, Characidae) and phylogenetic studies of Characiformes [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2020
In this study, the complete mitochondrial genome of Hyphessobrycon herbertaxelrodi is presented, and we also discussed its mitochondrial characteristics. The full length of the mitochondrial genome was 17,417 bp, including 13 protein coding genes (PCGs),

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

open access: yesEcology 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.

New Mitochondrial Genomic Resources for the Freshwater Fishes of the Sanaga River (Cameroon) [PDF]

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The Sanaga River Basin in Cameroon hosts a rich but poorly documented freshwater fish diversity. Here, we report the first complete mitochondrial genomes for nine species across four teleost orders, based on 39 specimens sequenced using Illumina NovaSeq.

Phylogenetic relationships within the speciose family Characidae (Teleostei: Ostariophysi: Characiformes) based on multilocus analysis and extensive ingroup sampling

open access: yesBMC Evolutionary Biology, 2011
Background With nearly 1,100 species, the fish family Characidae represents more than half of the species of Characiformes, and is a key component of Neotropical freshwater ecosystems.

Ontogeny of the Skeleton of Leporinus oliveirai (Characiformes, Anotomidae). [PDF]

open access: yesJ Morphol
ABSTRACT The skeleton is a rich source of characters used in phylogenetic studies of teleost fishes. However, the development of bones was studied in a limited number of species and few studies have been published describing the ontogeny of the Characiformes skeleton.

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus [PDF]

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Evolutionary trends of As51 satellite DNA and its colocalization with 45S ribosomal DNA: a conserved feature in Characiformes fishes [PDF]

open access: yesBMC Genomics
Background Satellite DNAs (satDNAs) can arise from diverse genomic regions, but determining their precise origin remains a major challenge. A previous study reported the colocalization of the As51 satDNA and the 45S ribosomal DNA (rDNA) in Astyanax ...
