Field record · Amphibia
Red-eyed tree frog
Agalychnis callidryas · a source-backed example record for comparing structure, variation, environment, and representation.
How not to overread the picture
Variation: Color can shift and life stage changes form dramatically; a bright adult portrait is only one slice of the animal’s life cycle.
Representation: Eye color is visually compelling but must not crowd out habitat, toe-pad, and life-stage evidence.
Process / function synthesis: An arboreal frog tied to humid rainforest environments and water-adjacent reproduction.
Evidence note
ADW supports neotropical rainforest habitat, adult color/structure, and water-associated reproduction.
