Description

The leopard catshark (Poroderma pantherinum) is a species of catshark, and part of the family Scyliorhinidae, endemic to the coastal waters of South Africa. Abundant in inshore waters under 20 m (66 ft) deep, this bottom-dweller favors rocky reefs, kelp beds, and sandy flats. Growing to a length of 84 cm (33 in), the leopard catshark has a stout body with two dorsal fins placed well back, and a short head and tail. It is extremely variable in color and pattern, with individuals ranging from almost white to black and covered by diverse patterns of black spots, blotches, rosettes, and/or lines. The color pattern changes with age and some forms seem to be location-specific, suggesting the presence of multiple distinct, local populations. In the past, some of the more distinct color forms have been described as different species. The leopard catshark inhabits the temperate and subtropical inshore waters off South Africa, from Saldanha Bay in the west to the mouth of the Tugela River in the east. There are old and almost certainly erroneous records from Mauritius and Madagascar. Given the color pattern diversity within the species, its range is likely fragmented into a number of small local populations along the South African coast. Bottom-dwelling in nature, the leopard catshark is most commonly encountered from the intertidal zone to a depth of 20 m (66 ft), though it has been reported from as deep as 256 m (840 ft) on the uppermost portion of the continental slope. This species favors rocky reefs, kelp forests, and sandy flats off beaches.
