What amphibians use camouflage?

Chameleons are well-known for their ability to change their skin color to match their surroundings. This adaptation helps them to camouflage themselves from predators and prey. Other amphibians that use camouflage include tree frogs, which have bumpy skin that helps them to blend in with tree bark, and certain species of salamanders, which have coloration and patterns that allow them to blend in with their habitat.
