Red wolf  (Canis rufus)

The red wolf is one of the world's rarest canids (2). The coat is a cinnamon or tawny red with grey and black touches (2), the back tends to be dark and the tail has a black tip (5). Red wolves are smaller than their relative, the grey wolf (Canis lupus), and have longer legs and shorter fur (5). Males are typically larger than females (6).
