The red-eyed tree frog lives in rainforests in southern Mexico. It has many current adaptations. Since it is so colorful, it sleeps during the day on the underside of leaves using suction cup-like toes and covers up all colors on its body for camouflage. It scares away predators by revealing its color and opening its bulging red eyes, which are also very good for seeing. In 2100 it will need to adapt to live underwater due to rising water levels. It could stick with its behavioral adaptation of covering all colors and being nocturnal and it does not need gills because it can absorb oxygen through its skin. But it will need to change its base color to a murkier green. Since it does not need to climb, it can replace its suction cup toes with webbed feet. A transparent third eyelid covering its eyes like goggles would also help.
