Kaloula pulchra ranges in size from 54-70 mm SVL for males, and 57-75 mm SVL for females. The body is stocky, with a small head and short, rounded snout. This frog will inflate itself when threatened.
The dorsum is dark brown, sometimes with irregular yellowish-brown spots. A narrow dark lateral stripe is present from the rear of the eye almost to the groin. This lateral stripe is separated from the mid-dorsal dark brown coloration by a thick yellow or orange stripe, which may itself be punctuated with several spots. The belly is mottled dirty yellowish brown. Males have a black throat.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Bangladesh, Cambodia, China, Hong Kong, India, Indonesia, Lao People's Democratic Republic, Malaysia, Myanmar, Nepal, Singapore, Thailand, Viet Nam. Introduced: Philippines.
Malaysian region distribution from AmphibiaWeb's database: Peninsular Malaysia, Sabah
This species is found in Bangladesh, Cambodia, China, Taiwan (introduced), Hong Kong, India, Indonesia, Lao People's Democratic Republic, Malaysia, Myanmar, Nepal, Singapore (introduced), Sri Lanka, Thailand, Viet Nam, Guam (introduced), and the Philippines (introduced) (Lazell and Lu 1996; Christy et al. 2007). It is found in wetland, riverbank, and forest edge habitats, as well as agricultural and residential areas, at elevations up to 750 m a.s.l. It breeds in seasonal rain pools or ponds (Kuangyang et al. 2004).
Life History, Abundance, Activity, and Special Behaviors
Generally breed during rainy season; males are usually heard during and after rainfall. They otherwise hide under burrows or vegetation and are nocturnal (Emerson 1976). Calls can be given while males float on the water surface. Calling is usually in chorus; however, adjacent calling males may alternate their calls (Kanamadi et al. 2002).
These frogs prey on ants (Berry 1965).
K. pulchra can exude highly sticky secretions, which are most likely used to deter predators (Evans and Brodie 1994). These secretions are noxious (unpleasant tasting) but did not contain detectable levels of toxins when tested (Daly et al. 2004).
Trends and Threats
This frog is adaptable and appears to be increasing in numbers (Kuangyang et al. 2004).
Relation to Humans
Kaloula pulchra is collected for local consumption as well as the international pet trade. It has been accidentally introduced to several countries (e.g., Guam), presumably via maritime or air-transport vessels and the pet trade. One specimen was discovered at the Perth airport in 2005 (Tyler and Chapman 2007), and one found in cargo at a New Zealand wharf (Gill et al. 2001), but there are no records showing the species has become established in either Australia or New Zealand. It often takes advantage of urban environments where it can be quite abundant (Kuangyang et al. 2004).
