Ecomorphology of fish locomotion with focus on neotropical species - DOI: 10.4025/actascibiolsci.v27i4.1271
Ecomorphology is the study between organism form and environmental factors. In this context, studies of functional morphology of locomotion provide explanations of result and cause to the phenotype-environment interactions.

| Resumo: | Ecomorphology is the study between organism form and environmental factors. In this context, studies of functional morphology of locomotion provide explanations of result and cause to the phenotype-environment interactions. The object of this paper was to review form and function relation of the extern structures of the morphology related to trunk and fins. The structures responsible for propulsion can be divided in trunk and fins. On the whole, the body can be fusiform, that offers the fish higher manobrability, or depressed, with better performance to explore substrate. According to these morpho-function aspects, the fins follow an evolution trend. Nevertheless, each one of the fins and the trunk can be used as the main organs of the propulsion making undulatory and oscillatory movements. On the whole, it is possible to detect an evolution trend from locomotion by undulation of the entire body to locomotion by the oscillation of the caudal fin |
