Living near humans: new diet items for the Big-headed Treefrog Polypedates megacephalus (Amphibia: Anura: Rhacophoridae) and its tadpoles in Vietnam

Key Points

Predation on the common house gecko highlights new dietary behavior of big-headed treefrogs.
First evidence shows treefrog tadpoles scavenging on dead lizards, expanding known diet items.
Urban environments serve as a unique habitat for these interactions, affecting local ecosystem dynamics.
The discovery emphasizes the adaptability of amphibian diets in changing environments.

Abstract

The predation by the Big-headed Treefrog Polypedates megacephalus on the Common House Gecko Hemidactylus frenatus and a failed predation attempt on the Tokay Gecko Gekko gecko are reported. In addition, for the first time, tadpoles of this treefrog species were observed scavenging on dead Asian Grass Lizard Takydromus sexlineatus, Boie's Wart Frog Fejervarya limnocharis, and unidentified species of the annelid order Haplotaxida. All observations were carried out in urban environments.
