Two more Exceptional Friends that we met at Kubah National Park in Borneo! They are Harlequin Tree Frogs (Rhacophorus pardalis), members of a group of frogs known as the flying frogs for their ability to glide from the treetops!
My contribution to @amphibianaday's 2023 amphibian pride parade.
Went with a Wallace's flying frog/Abah river flying frog/gliding frog/flying leaf frog/parachute frog (Rhacophorus nigropalmatus) because I have adored them since the first time I saw a photo of one. It can glide from tree to tree! How cool is that? Like a flying squirrel, except frog.
Drew this while waiting for the bus, and on the bus, with some touch-up at home.
That's no leaping lizard-- it's a flying frog! More specifically, it's Wallace's flying frog. This species gets its name from the webbing between its fingers and its elbows that allow it to glide from one tree branch to another, sometimes over distances of 15 m (50 ft)!

Cool Facts- It’s a bird! It’s a plane! It’s a… frog? The Wallace's flying frog, sadly, can’t truly fly. Instead, a thin fringe of skin between their toes and fingers allow them to parachute to the forest floor from their arboreal home. These frogs only fall with style when threatened by a predator or searching for prey. Their feet help them to glide up to 50 meters to a neighboring tree or to the ground. The Wallace's flying frog's giant toes help them to stick safely to trees after a quick glide. During the breeding season, females lay a nest of eggs on a branch above a pond or stream. As the tadpoles hatch, the nest breaks apart and drops the babies into the water below.
Rating- 12/10 (I am, I am, I am Superfrog and I can do anything.)
This picture documents a rare successful breeding of these guys in a zoo! Though they look like little babies, the thao whipping frog is one of the largest species of tree frog in the world! They have long webbed toes which allow them to drop from trees and glide, and often build their frothy nests above water so the tadpoles drop in when they hatch!

Wallace's Flying Frog: This South Asian/Indonesian species’ most notable feature is that it can glide up to 15 metres by spreading the webbing between its toes! It’s not the only species that does this, (R. dennysii, for example, does as well,) but it is one of the largest and most striking. They also have a few other quirks: instead of laying eggs directly in water, the female creates a foam nest in the foliage above a small pool and the tadpoles drop into it when they hatch. Recent research discovered that when fed high amounts of carotenoids, (pigments in certain plants, fungi, and bacteria,) they’re able to change colour in response to environmental changes. And they’ve been known to eat small birds in the wild!
Surinam Toad: Found in Northern South America, this frog is most known for its odd brooding habits. The female’s back encloses around her fertilized eggs, embedding them into her skin. She keeps them there for the entire 3-5 months it takes the tadpoles to develop inside the eggs before they emerge as full froglets. Since they’re entirely aquatic and also tongueless, they’re opportunistic hunters and likely lunge at anything that passes by – maybe even their own species, since some have been found with frog skin in their stomachs! In order to have maximum suction for capturing prey, its major organs can move down a third of the length of its body.
