Amietia angolensis (Bocage, 1866)
It is found in many protected areas. Localized threats include acid pollution from old gold-mine dumps. A. angolensis is not generally threatened (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
The adults spend the day floating amongst vegetation or basking on rocks above the water (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Wager (1986) found that tadpoles may grow to 80 mm in length (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
This species has long hind legs and a fair amount of webbing between the toes and is well adapted to jumping and swimming (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Being a common species that is active all year round, these frogs consume large numbers of flying and crawling insects. In turn, they constitute an important prey item for otters, large birds and snakes ((Rowe-Rowe 1977a, b; Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Poynton (1964) describes A. angolensis as being a widespread species distributed from Ethiopia, south through East Africa to southern Africa and westward to Angola (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Amietia angolensis inhabits the Grassland and Savanna biomes, and forest fringe. Annual rainfall in these areas is 500–900 mm. The species tolerates some habitat disturbance and is frequently associated with human habitation, taking up residence in ditches and ponds, often where reeds and water lilies are present (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Breeding takes place in shallow water along the edges of pools, dams, streams and slow-flowing rivers. These frogs breed in both standing water in flat areas and running water traversing slopes of more than 14 degrees (Channing 1979). Amietia angolensis is active throughout the year and breeding has been recorded in all months of the year (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
