Reindeer

Reindeer body clock switched off (BBC News)
* "Reindeer have no internal body clock, according to scientists."
* "Researchers found that the animals are missing a "circadian clock" that influences processes including the sleep-wake cycle and metabolism."
* "This enables them to better cope with the extreme Arctic seasons of polar day, when the sun stays up all day, and polar night, when it does not rise."
