Gorgons derive nutrients from the consumption of minerals, particularly the stone of their petrified victims, and any statues they create are likely to be gnawed thoroughly. They cannot digest metal or gems, so their dung (which resembles bitter-smelling gray powder) often contains small, raw crystals and nuggets of ore. Their aggression toward all other creatures means that there are few to no predators or other prey animals in their grazing grounds. Each herd is led by a dominant bull; solitary gorgons are usually adolescent bulls driven out of their herd by the lead bull.
