what is the average weight of an adult shark
Bull sharks are large and stout, with females being larger than males. The bull shark can be up to 81 cm (2.66 ft) in length at birth. Adult female bull sharks average 2.4 m (7.9 ft) long and typically weigh 130 kg (290 lb), whereas the slightly smaller adult male averages 2.25 m (7.4 ft) and 95 kg (209 lb). While a maximum size of 3.5 m (11 ft) is commonly reported, a single record exists of a female specimen of exactly 4.0 m (13.1 ft). The maximum recorded weight of a bull shark was 315 kg (694 lb), but may be larger. Bull sharks are wider and heavier than other requiem sharks of comparable length, and are grey on top and white below.
