Katak Paya or Masked Rough-sided Frog has a pointed head and snout projecting slightly in profile. The finders are long and the tips are slightly dilated. It has a light line on the upper lip that continues from below the eye to below the eardrum. Its dorsal colour can vary from medium reddish-brown to very dark brown. Swamp areas, primary and secondary forests are the natural habitat of this species.

Wallace´s Flying Frog is a very large tree frog with an almost rounded snout and very large hands and feet. The fingers and toes are fully webbed. The body is shiny green with lighter yellow on the lateral sides as well as on the toe pads and snout. The hind limbs are relatively larger than the front limbs and provide added thrust upon jumping. The males are slightly smaller than the females. This species is a resident of primary or logged forests at low elevation. It descends from the forest canopy to breed at turbid pools of water. It is also found on low tree branches near rain puddles by the logging area after heavy rain.

Brown Tree Toad (Pedostibes hosii)
Brown Tree Toad or its scientific name, Pedostibes hosii has a large, stout body with a thick bony ridge behind the eye and connected to a small paratoid gland. The fingers are long and distinctly shaped, probably an adaptation to climbing. The top of the head is smooth and the back has a few scattered warts. The females’ size is bigger than males. The color for the male are light brown while the females are black or dark purple with a pattern of yellow spots. It can be found mostly in undisturbed forests, but may be found on old secondary habitants. The species can be found in all parts of Borneo and also in Sumatra, Peninsular Malaysia and southern Thailand.

Spotted Tree Frog (Nyctixalus pictus)
This type of frog is small with relatively long snout and long hind limbs. The skin on the back, head and the upper surface of the limbs is rough, with many small spiny bumps. The body is reddish cinnamon brown or pale red, with white spots scattered on its back, along the edge of the snout and even on the upper eyelid. The upper half of the iris of the eye is white while the lower half is brown. This is one of the most distinctly colored and cannot be mistaken for any other species. The size of this species are almost the same except for the females which are slightly larger than the males.

Nyctixalus pictus lives in primary and old secondary forest and can be found most often in hilly terrain near water at all parts of Borneo except Brunei, southern Thailand, Peninsular Malaysia, Singapore, Sumatra and Philippines.

Horned Toad (Megophrys nasuta)
Megophrys nasuta have specific features that are different from other types of frogs. The “horn” is a very wide, pointed, with triangular projection from the edge of the eyelid. The hind legs are shorter than the front legs and normally males are often substantially smaller than females. The color is light clay to reddish brown, with one or two dark spots on the back. Using its leaf-like appearance for camouflage, Megophrys nasuta is virtually undetectable in the leaf litter of the forest unless it moves. This animal is perfectly designed to fit with its surroundings.

This species live in flat to steep rain forest with thick bamboos, where the area is damp and cool and is commonly found throughout Borneo, Sumatra and Peninsular Malaysia.
