It's hard to constantly monitor their activities, especially at night, but most of the information scientists are studying elephants in captivity, says Paul Manger, a neurologist who specializes in the field of brain research at the University «Vits in Johannesburg.
It should be noted that the elephants in zoos and in closed rooms, three bed for almost seven hours to 24 hours. The study was conducted with the use of electronic surveillance in the wild have shown that elephants in the wild behave differently – they slept only about two hours.

They need only three hours, says Paul Munger. New data suggest that larger animals need less sleep, and less is more. Some bats, for example, they sleep about eighteen hours a day, writes "Science News" quoted "RTS".
Scientists are now trying to link duration of sleep data on the size of the animals – large animals may need more time to stay awake to feed and support his massive body.
