The article presents a study which examines the developmental and morphological responses of Physalaemus (P.) Salbonotatus anuran larvae to chemical cues from Belostoma elongatum and Moenkhausia dichoroura predators. The study used experimental design and statistical analyses methods, such as principal component analysis (PCA) and analysis of variance (ANOVA). Results reveal that water-bug and predaceous fish provide major effect in P. albonotatus' morphology, growth rate, and development.
