The camouflage techniques of rainforest amphibians

The red-eyed tree frog (Agalychnis callidryas) uses flash coloration, revealing red, orange, and blue leg markings to startle predators while fleeing.

The glass frog (family Centrolenidae) has transparent skin on its underside, allowing it to blend with leaves by showing the background through its body.

Disruptive coloration, as seen in some frogs like the young Southern cassowary, uses patterns like stripes or spots to make their shape harder to detect.

Chromatophores are pigment-containing cells that allow frogs like the gray tree frog (Hyla versicolor) to change from green to gray or brown to match their surroundings.

The bird poop tree frog (Theloderma asperum) has a white and brown mottled appearance resembling bird droppings, an effective camouflage strategy.

Masquerade mimicry allows frogs like the leaf-like frog (Edalorhina perezi) to resemble inanimate objects, such as leaves, to avoid detection by predators.

Poison dart frogs use aposematism, displaying vibrant colors like red or blue to signal their toxic skin secretions, deterring predators instead of blending in.

The leaf-tailed gecko (Uroplatus sikorae) has a flattened tail and mottled skin that resemble moss-covered bark, allowing it to blend seamlessly with trees.

The Vietnamese mossy frog (Theloderma corticale) has bumpy, green skin that resembles moss, making it nearly invisible against rainforest rocks and plants.

Cryptic coloration, also called crypsis, enables amphibians like tree frogs to blend into their environment, such as leaves or bark, to avoid predators like birds and snakes.
