Resumo

Anableps anableps e Anableps microlepis, coletados na costa do Pará, por meio de dissecções do neurocrânio, mensurações morfométricas e análise volumétrica das principais estruturas encefálicas. Os resultados revelam que o encéfalo de Anableps apresenta semelhança com o padrão generalizado descrito para Teleostei, mas com particularidades relacionadas à sua especialização sensorial. As principais diferenças entre as espécies localizam-se no Telencephalon e Rhombencephalon. As variações identificadas sugerem que diferenças no comportamento migratório e na preferência por habitats distintos podem ter moldado a morfologia encefálica dos táxons. Este estudo demonstra que espécies filogeneticamente relacionadas podem apresentar modificações macroanatômicas expressivas associadas ao modo de vida, destacando o papel da plasticidade filogenética e das pressões adaptativas na evolução do encéfalo dos peixes. Os achados ampliam o conhecimento sobre a diversidade neuroanatômica no gênero Anableps e da ordem Cyprinodontiformes.
