It also found on land close to water bodies, especially during the night. Common and widely distributed in all climatic zones from sea level to about 600 m elevations. Jerdon's Bull Frog is mostly active during the rainy season and hides inside cracks in earth, dried ponds and other water bodies, holes in rivers and stream banks, underneath logs and stones, etc. during the dry season. 

ලංකා ගල්පර දිය මැඩියා [Lanka Galpara Madiya]/Sri Lankan Rock Frog (Nannophrys ceylonensis )

Kirtisighe's Frog/කීර්තිසිංහගේ මැඩියා[Kirthtisinhage Madiya] (Minervarya kirtisinghei [Fejervarya kirtisinghei])

A common endemic frog inhabiting streams in forests and adjoining plantations (Rubber estates), home gardens, marshy areas and such aquatic habitats of the wet zone below 1600m elevation. Sometime found far away from the water. 

Common paddy field frog/Vel madiya (Minervarya agricola [Fejervarya limnocharis])

Common paddy field frog can be distinguished from similar two other Fejervarya species by the absence of the longitudinal ridges on the dorsal area of the body and having more or less round tubercles instead. It is one of the commonest frog of the island found in paddy fields, streams, ponds and such other water bodies. However sometimes it encounters even far away from the water. It is distributed in both wet and dry zones of the country below about 1400m a.s.l

Skipper Frog/Utpatana Madiya (Euphlyctis cyanophlyctis)

Widely distributed frog, inhabiting all types of water bodies (prefer still water) from Sea level (Ex: Bundala) to higher elevations (Ex: Nuwaraeliaya).  It can be distinguished from its close relative Euphlyctis hexadactylus by its smaller size (50-60 mm from snout to vent) and smooth throat (hexadactylus has warts on its throat).  It is well adapted to aquatic life and frequently can be seen floating in water while keeping its bulging eyes and the nostril above the water surface. It can skip over the water surface when alarmed and hence its Vernacular names(Skipper/Utpatana).  

Spotted tree frog (Polypedates maculatus)

Spotted tree frog is widely distributed in both low country dry and wet zones including arid zone up to 460m above sea level. It is commonly encountered in anthropogenic habitats and during day time it use to hides in cool places such as inside bath rooms and banana groves.  This frog can change its color up to certain extent and dorsal color may vary from light brown and yellow to reddish brown. Dark brown patches on dorsal surface can be seen sometimes and hence the name maculatus, since maculatus in Latin is the one who bear spots or patches on its body.  Loreal region is dark brown and dark cross bars can be seen on dorsal side of limbs. 

Six-toe green frog (Euphlyctis hexadactylus)

Purely aquatic frog widely distributed in lowlands water bodies such as ponds, marshes,rivers and tanks with aquatic vegetations. Highest attitude where this frog is recorded is Warnagala area near Kuruwita of peak wilderness sanctuary (760m). Sometime it can be seen inside domestic wells too. Dorsal surface bright green or mud brown often with pale yellow or creamy white lateral line. Female is large and grows up to 120mm in length while small males grow only about 58-87mm.
