Bull. A bull is an intact adult male of the species Bos taurus.
   More muscular and aggressive than the females of the species, the cows, bulls have long been an important symbol in many cultures, and play a significant role in beef ranching, dairy farming, and a variety of other cultural activities, including bull fighting and bull riding. The female counterpart to a bull is a cow, while a male of the species that has been castrated is a steer, ox, or bullock, although in North America, this last term refers to a young bull, and in Australia to a draught animal.
   Use of these terms varies considerably with area and dialect. Colloquially, people unfamiliar with cattle may refer to both castrated and intact animals as bulls.
   A wild, young, unmarked bull is known as a micky in Australia. Improper or late castration on a bull results in it becoming a coarse steer, also known as a stag in Australia, Canada, and New Zealand.
   In some countries, an incompletely castrated male is known also as a rig or ridgling. The word bull also denotes the males of other bovines, including bison and water buffalo, as well as many other species of large animals, including elephants, rhinos, seals and walruses, hippos, camels, giraffes, elk, moose, whales, and antelopes. Bulls are much more muscular than cows, with thicker bones, larger feet, a very muscular neck, and a large, bony head with protective ridges
