Hose's frog (Odorrana hosii, often misspelled as O. hosei) is a true frog species with a wide range in Southeast Asia. This species was named after zoologist Charles Hose. Its closest living relatives appear to be O. chloronota which occurs to the north of Hose's frog's range, as well as O. livida and O. morafkai with a more limited range in Myanmar and Vietnam, respectively; these four appear to form a close-knit group wherein the northern species are barely closer to each other than Hose's frog is to any of them. Also quite closely related is O. megatympanum, another Vietnamese endemic.
This frog has a robust body with long, slender legs; males measure 50–60 mm, females 85–100 mm. The dorsal are dark green with brown sides, the ventral are pale, the limbs are marked with dark crossbars. Its finger- and toe-tips bear grooved discs.
This frog also have many varians of dorsal colour. Including full green, full brown, green with brown dots, and brown with green dots. Its call heard like "cit" of rats. Its tadpoles apparently lack suctorial discs. Hose's frog has been recorded from the Malay Peninsula south of the Kra Isthmus, on Phuket... Wikipedia →

Possible
About 20% of wildlife watchers report a Poisonous Rock Frog sighting in Kinabalu Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 27th most-seen of the 40 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July, September and December
In those months about 30% of wildlife watchers report a Poisonous Rock Frog in Kinabalu Park on a given day, against under 5% in January–February, May–June, August and October, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Poisonous Rock Frog sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Poisonous Rock Frog sightings, Kinabalu Park ranks 3rd at about 20%. The best odds are in Gunung Leuser National Park (Indonesia, about 30%) and Khao Sok National Park (Thailand, about 30%).
Same family: Ranidae
The closest relatives of the Poisonous Rock Frog that you can see in Kinabalu Park (family Ranidae, Typical Frogs) are Black-spotted Rock Skipper (about 40%), Kiau Borneo Frog (about 40%) and Green-spotted Foot-flagging Frog (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Poisonous Rock Frog is recorded against all the amphibians logged in Kinabalu Park (21 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
