The Cape file snake, Mehelya capensis, is a large, non-venomous snake belonging to the family Colubridae. It is one of several species in the genus mehelya, all of which are considered varieties of file snake. File snakes are set apart by their unusual scale patterns.

It is found from Natal northwards through the former Transvaal and Zimbabwe, and westwards to the Caprivi Strip and Namibia, thence northwards to Cameroon and Somalia.
With an average length of about 120 centimetres (3 ft 11 in), specimens of 165 cm (5 ft 5 in) have been recorded. It has a very flat head and its body is strikingly triangular in cross-section.
The Cape file snake's dorsal scales are strongly keeled with extensive pink-purple bare skin between the scales. Its colour is mostly grey to grey-brown, but occasionally dark olive to purple-brown. The prominent vertebral stripe is white to yellow, while the belly is ivory white to cream.
Three subspecies are recognized, including the nominate race.
Mehelya capensis prefers savannahs and coastal forests.
Though it is not venomous the Cape file snake is a highly successful predator of other snakes, easily following a scent trail and apparently immune to all venom. It also preys on small vertebrates.
Rarely attempting to bite when captured, it may defecate in self-defence.[3]
