Acontias percivali, also known as Percival's legless lizard, Tanzanian legless lizard, and Percival's lance skink, is a small, legless (snake-like) species of lizard in the family Scincidae, collectively known as "skinks".
Percival's lance skink inhabits savannas by burrowing just below the surface of the soil.
The three subspecies of A. percivali are:
A. p. occidentalis has been considered a full species by Lamb et al. (2010) and by Wagner et al. (2012).
Percival's lance skink can be identified by its copper-brown back and gold underside. It is an insectivores that specializes in feeding on beetle larvae, earthworms, and other slow-moving invertebrates.
A. percivali is ovoviviparous and has one to five young at a time.
Although this animal is poorly understood, it is occasionally seen in pet shops. Most Acontias specimens in the pet trade are wild-collected. In captivity, they require a deep layer of sandy substrate and hollow hiding places on the surface. Captive breeding may be possible, but currently has not been accomplished commercially.
