Number of hours of elephant sleep

Many studies of elephants seem to have drawbacks. They either rely on captive elephants, which have different sleep schedules than wild elephants, or do not distinguish between rest periods and sleep periods. This is why Manger and his colleagues monitored two wild African elephants In the Chop National Park in Botswana, which they monitored for 35 days, using a special implant to record the movements of the elephant trunk. These movements indicate that the elephant is asleep or not, and the GPS device to locate the elephant's sleep. Her eyes on some nights Perhaps this was because of the sense of turmoil, and these devices recorded a lack of sleep elephants for up to 46 hours,This result was associated with large movements of elephants up to 30 kilometers, indicating that their disturbance may be due to predation, or overfishing, and despite the lack of sleep on previous nights, elephants do not sleep longer on the following nights
