The Vietnamese mossy frog gets its name from its appearance, which looks much like, you guessed it, moss! The mossy frog's red, green, and black coloration and uneven, bumpy texture enable it to blend in among mosses and lichens within its habitat. To protect itself from predators, the mossy frog, when threatened, will fold itself into a ball and play dead. These frogs also have sticky discs at the end of each toe, making them skillful tree climbers.
