| Summary: | "Visually aposematic prey warn their potential predators about their noxious condition by exhibiting conspicuous coloration. The larvae of some phyllomedusine frogs bear bright patches on the body or tail that suggest an anti-predator role, yet the experimental evidence of aposematism in anuran larvae is notoriously scarce. Here, we assessed and compared the conspicuousness and skin toxicity of three species of phyllomedusine larvae that differ in coloration: Phyllomedusa vaillanti, Phyllomedusa bicolor y Callimedusa tomopterna. These conspicuous colorations found on the dorsal area of the larvae could be directed to aerial predators, so we evaluated the distribution of the larvae in the depth of the water column." -- Tomado del Formato de Documento de Grado. |
