The leopard catshark (''Poroderma pantherinum'') is a species of Scyliorhinidae, catshark, and part of the family (biology), family Scyliorhinidae, endemism, endemic to the coastal waters of South Africa. Abundant in inshore waters under deep, this benthic fish, bottom-dweller favors rocky reefs, kelp beds, and sandy flats. Growing to a length of , 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. Mainly nocturnal in habits, after dusk the leopard catshark hunts for small, benthic bony fishes and invertebrates in sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
