  "description": "Many scientists believe the red eyed tree frog developed its vivid scarlet peepers to shock predators into at least briefly questioning their meal choice. The red eyed tree frog flashes its brightly colored body parts when startled. It sleeps by day with its eyes closed and body markings covered, stuck to leaf-bottoms. \n\nchild friendly persona\n\nPersonas by LisaAtTheBeach"
