• How many hours do elephants sleep?

 It seems that many of the studies conducted on elephants have some flaws, they are either based on captive elephants, which have different sleep schedules from wild elephants, or they do not distinguish between rest periods and sleep periods, and for this reason, Manger and his colleagues monitored two female African elephants Wilderness in Chub National Park, Botswana, for 35 days.

This was done by using a special implant that recorded the movements of the elephant's trunk, and these movements indicated whether the elephant was sleeping or not, and a GPS device to determine where the elephant was sleeping. This study showed that the elephants barely managed to close their eyes on some nights, and this was probably because they felt restless.

These devices also recorded that the elephants did not sleep for up to 46 hours, and this result was associated with large movements of the elephants up to 30 km, which indicates that their disturbance may be due to predation, or poaching, and despite the lack of sleep in the previous nights, the elephants Do not sleep any longer the following nights.

•  African elephant sleeping

After observing two maternal elephants, the researchers found that they sleep two hours a day on average, and often two days go by without sleeping, and the researchers suggest that African elephants may be the shortest mammals in the duration of sleep on Earth.

As a professor of anatomical sciences at the University of the Witwatersrand in South Africa, Paul Manger, says that elephants do not sleep much, and this appears to be related to their large size, and he also found that the brains of elephants contain unusual aspects related to sleep systems, which indicates that their sleep periods should be To be very short.
