How giraffes survive on less than two hours of sleep and still stay alert to predators in the wild
Giraffes exhibit a unique, fragmented sleep pattern, taking dozens of micro-naps lasting only one to three minutes each. This strategy, averaging just 8.6 minutes of true sleep per night, allows them to remain alert to predators on open grasslands. Calves and giraffes in safer environments sleep longer, while REM sleep occurs briefly when lying down.
