Red-eyed tree frogs rely on camouflage to protect themselves against predators. During the day, they sleep on the underside of leaves, with their brightly colored body parts covered and their eyes closed.
According to National Geographic, when red-eyed tree frogs are threatened, they expose their red eyes, yellow legs and orange feet to repel predators. They are not poisonous despite having vibrant colors. The frog's bright green body startles predators at night, and this gives the frog a chance to flee. This mechanism is known as startle coloration.
Red-eyed tree frogs are popular as pets, but they require high maintenance. The tank where the frogs are kept needs an appropriate temperature and humidity to ensure their survival.
Red-eyed tree frogs are nocturnal animals and prey on moths, flies, crickets and other insects. Their natural habitat spreads across the rainforests of southern Mexico, Central America and northern Colombia, where they can be found near rivers and lakes.
National Geographic explains that the natural habitat of red-eyed tree frogs is shrinking. The frogs depend on rivers and lakes within the rainforest, especially during mating season. Their habitat is being deforested and transformed into urban living areas. The species itself is not endangered, but the shrinking habitat is a reason for concern.
