[3], Based on morphological data, Jack Garrick suggested in 1982 that the blacknose shark has a sister relationship to a group containing the whitecheek shark (C. dussumieri) and the blackspot shark (C. sealei), while Leonard Compagno proposed in 1988 that this shark belongs in a group with five other species, including the silky shark (C. falciformis) and the blacktip reef shark (C. melanopterus). [9] The body is covered with overlapping dermal denticles that bear five to seven longitudinal ridges (three in very young individuals) leading to three to five marginal teeth. Bony fishes and small sharks make up the vast majority of the bull shark’s diet.
