Caribou facts

摘要

Canada has three types of caribou: Peary, barren-ground and woodland. These types are sub-classified by eco-type, based on where they live and how they behave. This member of the deer family is the only ungulate [hoofed grazer] with antlers on both male and female. Adult bulls shed theirs in late autumn after mating, but the females often retain theirs until spring. A bull's antlers can grow as much as 2.5 centimetres every day.
