The white-throated monitor (Varanus albigularis albigularis) is a lizard found in southern Africa. They are usually gray-brown with yellowish or white markings, and can reach up to 2 metres (6.6 ft) in length. They are found in Southern Africa, northwards to Angola, Zambia, and Mozambique.

Taxonomy
editFirst described by François Marie Daudin in 1802,[1] these lizards were previously classed as a subspecies of Varanus exanthematicus, but have since been declared a distinct species based upon differences in hemipenal morphology.[2] The generic name Varanus is derived from the Arabic word waral ورل, which is translated to English as "monitor". Their specific name comes from a compound of two Latin words: albus meaning "white" and gula meaning "throat".
Diet
editVaranus albigularis albigularis are generalists, feeding opportunistically on a broad variety of prey in the wild. Tortoises make up a significant part of their diet, and are swallowed whole due to the hard shell. Otherwise, they consume very little vertebrate prey, eating primarily invertebrates, especially millipedes, beetles, molluscs and orthopterans. Millipedes for example form nearly a quarter of their diet; the monitors are apparently resistant to its poisonous secretions. Although not averse to occasionally scavenging the corpses of vertebrate prey, even those as large as vervet monkeys, such prey seems usually too fast to catch for these monitors. This contrasts with what is often a diet of mostly vertebrates in captivity, such as rodents or poultry.[3]
Predation
editIt is hunted by birds of prey such as eagles.
Captivity
editThis subspecies is kept as a pet.
