It seems wild elephants don't need a full eight hours of sleep every night to maintain one of the longest memories in the animal kingdom.
野生大象似乎不需要每晚睡八小時來維持動物王國里擁有最長記憶的頭銜。
According to one team of scientists in South Africa, wild elephants sleep an average of just two hours a night,that's less than any other animal on record.
根據南非一組科學家的研究，野生大象平均每晚只睡兩個小時，這比其它任何動物都要少。
That's surprising because elephants are known for their incredible memories. And studies have shown that sleep and memory are connected.
這是令人驚訝的，因為大象以其令人難以置信的記憶而聞名。研究表明睡眠和記憶是相互聯系的。
The team also found the pair of wild African elephants it tested slept in bursts. They slept both lying down and standing up. And sometimes, they didn't sleep at all.
研究小組還發現他們測試的這對野生非洲大象睡一會兒就會突然醒來。它們躺著和站著都能睡。有時，他們根本不睡覺。
Sleep experts are taking the study into account, but others say it's possible wild elephants have evolved to thrive with little or no sleep. The enormous mammals are busy eating 17 to 18 hours each day.
睡眠專家正在考慮這項研究，但也有人說，野生大象可能已經進化到需要很少或根本不需要睡眠。這個體型龐大的哺乳動物每天有17到18個小時忙著進食。
