Penguins can survive extreme conditions by taking thousands of micro naps each day. During breeding season, some penguins sleep for only a few seconds at a time, adding up to more than ten hours of rest per day. These ultra short sleep cycles allow them to stay alert for predators and protect their eggs while still giving their brains enough recovery. It is a unique adaptation that shows sleep does not always need long uninterrupted hours to be effective.
