The young or sick are the easiest to catch. A pack of wolves chases the caribou and surrounds it if it moves away from the herd. A young calf must quickly become strong enough to run and escape enemies like wolves, bears, and foxes. The calves are born covered with warm fur and with their eyes open. They are able to walk and run soon after birth.
Caribou lose their anters once a year, then grow new ones.
Both the females and males have antlers.
