Red eyed tree frogs utilize a technique called "startle coloration" to elude predators. Because most of their predators use vision as their primary sense, this technicolor frog may overwhelm their brains with too much information allowing the frog the extra moment it needs to escape. While sleeping, this frog reveals only its green body, but when awakened it flashes a confusing kaleidoscope of colors. In spite of its strong coloration, these frogs are not venomous.
