Adults are generalist predators and scavengers, and can hold food items in their toothed mouths while breaking it apart with their claws using an overhead kick (Avila and Frye 1978). These behaviours can be detected by other adults in the vicinity and sometimes lead to a feeding frenzy (Frye and Avila 1979). Most food items for post-metamorphic X. laevis are benthic macro-invertebrates, such as chironomid larvae. However, a wide variety of food sources are used from all microhabitats in water bodies, including carrion and terrestrial food items (Measey 1998a, b). Even the largest animals take very small prey items, such as zooplankton and ostracods . X. laevis plays an important role in the ecology of southern African wetlands because it is widespread and abundant, and it is a voracious predator as well as an important prey item for several mammalian, avian and reptilian predators (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
Xenopus laevis tested positive for Batrachochytrium dendrobatidis in Botswana at the Kanye Youth Centre in April 1969 (Weldon 2005). It also tested positive in the South African cities of Zeekoeivlei in 1938, Moordenaarshoek and Harrismith in 1972, Natal in 1973, Rosendal and Touw River in 1974, Phillipi in 1982, Florisbad in 1987, Koffiefontein and Sannaspos in 1991, Mooi River in 1995, Kommissiepoort in 1996, Windsorton Road in 1998, Stellenbosch and Klapmuts in 2001, Strand, Wellington, and Botrivier in 2002 and Kammieskroon in 2004 (Weldon 2005).
