Caribou, calls, and more!
Reindeer, or caribou, can outperform all other land animals in their energy efficiency - so are a fitting choice as the legendary Christmas sleigh-pullers! They're more usually seen on their mammoth annual migration to the Arctic during which the North American herds might travel for more than 5,000km - an extraordinary feat that takes them further than any other land mammal.
