African wild dog
The African wild dog (Lycaon pictus), also called painted dog and Cape hunting dog, is a wild canine native to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by dentition highly specialised for a hypercarnivorous diet and by a lack of dewclaws.
It is estimated that there are around 6,600 adults (including 1,400 mature individuals) living in 39 subpopulations, all threatened by habitat fragmentation, human persecution and outbreaks of disease. As the largest subpopulation probably consists of fewer than 250 individuals, the African wild dog has been listed as endangered on the IUCN Red List since 1990.
The African wild dog is a specialized hunter of terrestrial ungulates, mostly hunting at dawn and dusk, but also displays diurnal activity. It captures its prey by using stamina and cooperative hunting to exhaust them. Its natural competitors are lions and spotted hyenas: the former will kill the dogs where possible whilst the latter are frequent kleptoparasites. Like other canids, the African wild dog regurgitates food for its young but also extends this action to adults as a central part of the pack's social unit. The young have the privilege of feeding first on carcasses.
The African wild dog has been revered in several hunter-gatherer societies, particularly those of the San people and Prehistoric Egypt.
The English language has several names for the African wild dog, including African hunting dog, Cape hunting dog, painted hunting dog, painted dog, painted wolf, and painted lycaon. Though the name African wild dog is widely used, 'wild dog' is thought by conservation groups to have negative connotations that could be detrimental to its image; one organisation promotes the name 'painted wolf', whilst the name 'painted dog' has been found to be the most likely to counteract negative perceptions.
The earliest written reference for the species appears to be from Oppian, who wrote of the thoa, a hybrid between the wolf and leopard, which resembles the former in shape and the latter in colour. Solinus's Collea rerum memorabilium from the third century AD describes a multicoloured wolf-like animal with a mane native to Ethiopia.
The African wild dog was scientifically described in 1820 by Coenraad Jacob Temminck after examining a specimen from the coast of Mozambique, which he named Hyaena picta. It was later recognised as a canid by Joshua Brookes in 1827 and renamed Lycaon tricolor. The root word of Lycaon is the Greek λυκαίος (lykaios), meaning 'wolf-like'. The specific epithet pictus (Latin for 'painted'), which derived from the original picta, was later returned to it, in conformity with the International Rules on Taxonomic Nomenclature.
Paleontologist George G. Simpson placed the African wild dog, the dhole and the bush dog together in the subfamily Simocyoninae on the basis of all three species having similarly trenchant carnassials. This grouping was disputed by Juliet Clutton-Brock, who argued that other than dentition too many differences exist among the three species to warrant classifying them in a single subfamily.
