Karachi alone has upwards of 400,000 head of water buffalo in 2021, which provide dairy as well as meat to the local population.

Resembling the modern bison species, especially the American wood bison (Bison bison athabascae), [9] the steppe bison was over 2 m (6 ft 7 in) tall at the withers, reaching 900 kg (2,000 lb) in weight.
