The East African black mud turtle (Pelusios subniger) is a species of turtles in the Pelomedusidae family, traditionally found in eastern and southeastern Africa, including Madagascar. Nonindigenous populations exist on Mauritius Island, Glorieues Îsles, and Diego Garcia. This species is commonly confused with Pelusios castaneus.
There are a few diagnostics that distinguish P. subniger from other species of mud turtles. The plastral color patterns are usually with a symmetrical yellow and brown/blackish pattern, each shield yellow mesially and dark towards the sulci. The head color is usually uniform brown, sometimes spotted with black. The skin is grey/black, and the outer surfaces of limbs are black.[1]
