          Abstract

          Abstract Fishes inhabiting Amazonian floodplain lakes exhibits a great variety of body shape, which was a key advantage to colonize the several habitats that compose these areas adjacent to the large Amazon rivers. In this paper, we did an ecomorphological analysis of twenty abundant species, sampled in May and August 2011, into two floodplain lakes of the lower stretch of the Solimões River. The analysis detected differences among species, which could be probably associated with swimming ability and habitat use preferences.

          Resumo Os peixes que habitam os lagos de várzea da Amazônia apresentam morfologias bastante diversas, possibilitando a exploração bem sucedida dos diferentes habitats que formam estas áreas adjacentes aos grandes rios amazônicos. Neste artigo, relatamos os resultados de uma análise ecomorfológica de vinte espécies abundantes, coletadas em maio e agosto de 2011, em dois lagos das várzeas do trecho inferior do rio Solimões. As analises indicaram diferenças entre as espécies como função do atributos ecomorfológicos, provavelmente associadas com a capacidade natatória e com preferências por habitat.
