How does the red eyed tree frog protects itself?

Answer 1

• some tree frogs do have a toxin in their skin that could sometimes cause some skin irritation
• the color of the eye

The way that Red Eyed Tree Frogs protect them selves is through camouflage, they hide in anything that contains bright colors they do this to lose the predator's interest. This is how they keep them selves from being injured.
they have toxin on their skin
Bright markings along the sides and limbs reduces predation. Most animals that prey on A. callidryas (some bats, snakes, and birds) often rely on their vision. When the frog moves to avoid the predator the bright colorations flash into view (hence their name, flash colors) and throw off the predator. This is achieved by leaving a ghost image in the visual field of where the frog was originally. This confuses the predator and gives the frog time to hide. These flash colors may also deceive predators by making the frog appear poisonous. Red-eyed tree frogs are not poisonous and rely on camouflage to protect them. During the day, they remain motionless, cover their blue sides with their back legs, tuck their bright feet under their belly, and shut their red eyes. Thus, they appear almost completely green, and well hidden among the foliage. Their eyes seem to glow in the dark.
