Amazonian Horned Frogs Master Camouflage Within Dense Leaf Litter
In the hidden, sodden corners of the Amazon Basin, where the forest floor transitions into a mosaic of decomposing foliage, resides one of the most specialized predators in the herpetological world: the Amazon Horned Frog (Ceratophrys cornuta). While its larger relatives often dominate the literature, recent behavioral observations in remote Peruvian and Brazilian corridors have shed new light on how these sedentary hunters maintain their dominance in an environment defined by constant competition and rapid decomposition. Known colloquially as the Pac-Man frog for its disproportionately cavernous mouth, the Amazon Horned Frog is a master of patient, tactical survival. Unlike the nomadic foragers of the canopy, this species is a specialist in stillness. By burrowing into the damp topsoil, it transforms its own body into a trap, waiting for unwary invertebrates or smaller vertebrates to pass within strike range. Our observations suggest that their reliance on high-moisture, micro-climati...
