背面の脊椎 (合計) : 0; 肛門の骨: 0. A stocky shark with long nasal barbels and a highly variable color pattern of black spots, rings and lines in horizontal rows on a grey to whitish background; white below (Ref. 5578). There are 3 different forms, the typical 'pantherinum' with lines and rosettes of spots, and two extreme forms, 'marleyi' with large dark spots (formerly considered a separate species), and 'salt and pepper' with small, densely packed black spots, intermediates between these extremes are extremely common (Ref. 5578).
Found on or near the bottom of warm-temperate waters, from the intertidal zone to 256 m (Ref. 5578). Prefers rocky reefs (Ref. 5578). Nocturnal (Ref. 244). Feeds on small bony fish, crustaceans, octopus and polychaete worms (Ref. 5578). Oviparous (Ref. 50449). Readily kept in captivity (Ref. 244).
