The barbeled houndshark (Leptocharias smithii) is a species of ground shark and the only member of the family Leptochariidae. This demersal species is found in the coastal waters of the eastern Atlantic Ocean from Mauritania to Angola, at depths of 10–75 m (33–246 ft). It favors muddy habitats, particularly around river mouths. The barbeled houndshark is characterized by a very slender body, nasal barbels, long furrows at the corners of the mouth, and sexually dimorphic teeth. Its maximum known length is 82 cm (32 in).

Likely strong-swimming and opportunistic, the barbeled houndshark has been known to ingest bony fishes, invertebrates, fish eggs, and even inedible objects. It is viviparous with females bearing litters of 7 young; the developing embryos are sustained via a unique globular placental structure. The International Union for Conservation of Nature (IUCN) has assessed the barbeled houndshark as Vulnerable, as heavy fishing pressure occurs throughout its range and it is used for meat and leather.
