Frequently asked
A strong candidate: a bull elk's antlers are the fastest-growing bone tissue of any mammal, adding up to an inch a day and 40 pounds in a single summer — then the bull drops the whole rack every winter and grows a new one from scratch. The bull even pulls calcium from its own skeleton to fuel that growth.
Elk are fast for their size — a bull can run roughly 40 miles per hour in short bursts and is a strong swimmer. Combined with their ability to cover steep, broken mountain country quickly, this speed is a major reason healthy adult elk are hard for predators to catch, which pushes most predation onto calves and the weak.
'Wapiti' comes from the Shawnee and Cree word for 'white rump,' describing the pale patch on the animal's hindquarters. Biologists prefer 'wapiti' because 'elk' is ambiguous — in Europe, 'elk' refers to the moose. In everyday North American usage, though, 'elk' is universal.
