Pterobrycon myrnae , a remarkable new glandulocaudine characid fish from Costa Rica
, 2016 A new species of characid fish, in which the males have greatly enlarged scales on the middle of the flanks, is described from southern Costa Rica. During courtship the expanded tips of these "paddle sea les" serve as a stimulus to the female which later takes a spermatophore into her mouth. The peculiar sexual dimorphism of P.

Zootaxa, 2014
Astyanax douradilho, new species, is described from the rio Tramandaí system, coastal drainage of Rio Grande do Sul State, Brazil. The new species is distinguished from its congeners by possessing 37–39 perforated scales along the lateral line, 3–5 maxillary tricuspid teeth, 22–24 branched anal-fin rays, absence of a conspicuous dark stripe from ...

Miocene Characid Fishes from Colombia: Evolutionary Stasis and Extirpation
Science, 1986Fossil fishes from the Miocene La Venta fauna of the Magdalena River Valley, Colombia, are identified as Colossoma macropomum (Characidae), a living species from the Orinoco and Amazon basins. The fossils document a long and conservative history for a species that is highly specialized for feeding on streamside ...

Zoologischer Anzeiger, 2017
The relationship between diet and mouth and tooth morphology among eleven characid species is evaluated herein. Specifically, we tested for: (1) significant differences among the diets and (2) corresponding variation of mouth and tooth morphology. Fishes were collected bimonthly during 2012 and 2013 using electrofishing techniques in the Alto Jacui sub-

Digestive flexibility during fasting in the characid fishHyphessobrycon luetkenii
Journal of Morphology, 2011AbstractDigestive flexibility is a widespread phenomenon among animals, and the congruence between empirical data and optimal digestion models strongly supports the idea that it has evolved by natural selection. However, current understanding of the evolution of this amazing flexibility is far from being comprehensive.

Aggressive Mimicry by the Characid Fish Erythrinus erythrinus
Ethology, 1997AbstractThe young Erythrinus erythrinus mimics the colour pattern of the female of its specific prey, the cyprinodont fish Rivulus agilae. The male Rivulus is attracted by the predator, and, when performing sexual display in front of it, is caught by the tail and swallowed.

Trophic dynamics resilience of a characid fish in varied Amazonian stream landscapes
Marine and Freshwater ResearchContext: Knowledge of how fish species’ diets are influenced by local environmental changes is essential for their management and conservation. Aims: We evaluated the effects of a wide range of land uses and physical habitat attributes on the diets of ...
