About This Dataset
Animals That Sleep the Most
How many hours a day different animals spend asleep, on average. The koala tops the list at up to 22 hours - conserving energy on its low-nutrient eucalyptus diet - while humans need only about 8. Figures are approximate.
Analysis
The top three in Average Sleep per Day (hours) are Koala (22), Sloth (20) and Little brown bat (19.9). The 8 entries cover a range of 14, from 22 down to 8. First and second are separated by 2, so the leader sits inside the field rather than apart from it. The other 6 are bunched between 8 and 19.9.
