The largest of the "requiem sharks" (in the genus Carcharhinus) seems to be the dusky shark (C. obscurus), at up to 4.2 m (14 ft) and a weight of 350 kg (770 lb). [29] However, the bulkier bull shark ( C. leucas ) has been estimated to weigh about 575 kg (1,268 lb) in recent specimens that measured over 4 m (13 ft) long. [ 30 ]
