Platymantis corrugatus (rough-backed forest frog) is a species belonging to Ceratobatrachidae family. This species is known because of its size and longitudinal ridges on its back. It is endemic to some major islands in the Philippines and it inhabits both primary and secondary forests. The major threat to this species is habitat loss due to deforestation. Prevention to further logging activities is the most important conservation measure.
Platymantis dorsalis (Dumeril's wrinkled ground frog) is a forest frog species in the Ceratobatrachidae family and can only be seen in some major islands in the Philippines. This species is threatened by climate change and habitat loss due to deforestation, wild fires, etc. Get to know them and help them survive in the wild. :)
Tiny frog that jumped across my path and hid in leaf litter.
It could be several Platymantis species that I have since researched but the colouration didn't match any photos that I found online. Its size and shape also look very similar to a Leptolalax species that I am more familiar with.
Thanks to Arvin Diesmos of Philippine herpwatch.org who identified it as P. corrugatus.
The true frogs, family Ranidae, have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on most continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Asia, Madagascar, Africa, and from the East Indies to New Guinea; the species native to Australia—the Australian wood frog (Hylarana daemelii)—is restricted to the far north.
