It’s a question that keeps some scientists awake at night: Do spiders sleep?
這是一個讓一些科學家夜不能寐的問題：蜘蛛會睡覺嗎？
Daniela Roessler and her colleagues trained cameras on baby jumping spiders at night to find out. The footage showed patterns that looked a lot like sleep cycles: The spiders’ legs twitched and parts of their eyes flickered.
丹妮拉‧羅斯勒和她的同事在夜間用相機對準跳蛛幼蛛拍攝，以找出答案。畫面顯示的模式看起來很像睡眠週期：蜘蛛的腿抽搐，部分眼睛來回轉動。
The researchers described this pattern as a “REM sleep-like state.” In humans, REM, or rapid eye movement, is an active phase of sleep when parts of the brain light up with activity and is closely linked with dreaming.
研究人員用「快速眼動睡眠狀態」形容他們觀察到的這種模式」。人類睡眠的快速眼動（REM）指的是睡眠過程中的活躍階段，大腦有一部分處於清醒活動狀態，與作夢有密切關係。
Other animals, including some birds and mammals, have been shown to experience REM sleep. But creatures like the jumping spider haven’t gotten as much attention so it wasn’t known if they got the same kind of sleep, said Roessler, an evolutionary biologist at the University of Konstanz in Germany.
其他動物，包括一些鳥類和哺乳動物，已被證明會經歷快速眼動睡眠。但德國康斯坦茨大學的進化生物學家羅斯勒說，像跳蛛這樣的生物並沒有受到太多關注，所以不知道牠們是否有同樣的睡眠。
