This stocky shark has a conical nose and a slightly flattened head (3). It is a dark brown or beige colour above, with blotches of darker colour, and paler underneath (4). The teeth of this species are especially distinctive, having a fang-like appearance and being visible even when the mouth is shut (5). There are two dorsal fins, which are a similar size to the anal fin; the upper lobe of the tail is larger than the lower one (3). Sharks have a sixth sense that enables them to detect electric currents, and the receptive pores are located on the under surface of the sand tiger's snout (5).
