At a glance the quick version
Looks how to spot one
Slender, long-limbed tree frog with smooth skin and sticky toe pads
A lean climbing frog with long legs, webbed toes ending in suction-like pads and smooth skin kept moist by mucus glands. Its huge red eyes have vertical pupils and are covered by a see-through third eyelid when the frog rests. Females are clearly larger than males.12
Personality what they are like
A quiet, nocturnal frog that rests motionless through the day and wakes at dusk to hunt. It is a watch-and-enjoy pet rather than one for frequent handling.123
Daily activity how busy a day looks
Active at night, climbing and leaping between branches and leaves while searching for insects.23
Grooming and care the hands-on bits
Needs consistently humid air, around 80 percent or higher, and a tall enclosure with plenty of leaves and branches to climb and sleep on. Keep it mostly as a display animal.12
Home where they are happiest
Tall, planted rainforest-style terrarium with broad leaves, climbing branches and a water area, kept warm and very humid to match its humid lowland forest home.12
Food basics what goes in the bowl
Insectivore. Adults eat flying and hopping insects such as moths, crickets, katydids, grasshoppers and flies.123
Company who they like around
A social, sedentary species in the wild that gathers near ponds in the breeding season; males call and wrestle to win females.21
The story where it all began
Edward Drinker Cope described the frog in 1862 under the name Hyla callidryas. Thanks to its vivid colours it has become a widely used symbol of tropical rainforests and their conservation.13
Fun facts for the dinner table
- 1
When disturbed, it suddenly opens its red eyes and shows its orange feet and blue-yellow flanks, a 'startle display' that can confuse a predator for a moment.1
- 2
Unhatched embryos can hatch early when they sense the particular vibrations of a predator or flood.1
- 3
Males shake branches to signal to rivals, one of the first documented cases of tree-dwelling vertebrates communicating by vibration.1
- 4
Females lay clutches of about 40 eggs on the underside of leaves hanging over water, so the tadpoles drop straight into the pond.2
- 5
Its skin colour can shift from leaf green to reddish brown depending on its mood.2
