The Black-spotted Rock
Frog is one of six species (Arifin et al, 2011) in the genus Staurois
which are also known as 'Splash Frogs'. Frogs of this genus inhabit fast-flowing,
clear, rocky streams in lowland or hilly rainforest in Borneo and the
Philippines.
Staurois guttatus is a relatively small frog, with a maximum snout-vent length of 3.7 cm
in males, and 5.5 cm in females. Its body is slender, and its head is
slightly larger than the body. Its hind limbs are long and slender, and its
forelimbs relatively short.
Its body and upperside of its limbs is covered with abundant small, rounded
warts. Its ground colour is medium brown to olive green, patterned with
numerous dark blotches. Its underside is pale green or yellowish.
The tadpoles are small and colourless, but appear reddish as the blood can
be seen through the skin.
This species occurs in many parts of Borneo, including the territories of
Kalimantan (Indonesia), Sabah and Sarawak (Malaysia) and Brunei.
