Do spiders sleep? Study suggests they may snooze like humans

蜘蛛会睡觉吗？研究表明它们可能像人类一样打盹

It’s a question that keeps some scientists awake at night: Do spiders sleep?

这是一个让一些科学家夜不能寐的问题：蜘蛛会睡觉吗？

Daniela Roessler and her colleagues trained cameras on baby jumping spiders at night to find out.

丹妮拉?罗斯勒和她的同事在夜间用相机对准小跳蛛幼蛛拍摄，以找出答案。

The footage showed patterns that looked a lot like sleep cycles: The spiders’ legs twitched, and parts of their eyes flickered.

画面显示，这些模式看起来很像睡眠周期：蜘蛛的腿抽搐，部分眼睛来回转动。

The researchers described this pattern as a “REM sleep-like state.”

研究人员将这种模式描述为“快速眼动睡眠状态”。

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.

人类睡眠的快速眼动指的是睡眠过程中的活跃阶段，大脑有一部分处于清醒活动状态，与做梦有密切关系。

Other animals, including some birds and mammals, have been shown to experience REM sleep.

其他动物，包括一些鸟类和哺乳动物，已被证明会经历快速眼动睡眠。

But creatures like the jumping spider haven’t gotten as much attention, so it wasn’t known whether they got the same kind of sleep, said Roessler, an evolutionary biologist at the University of Konstanz in Germany.

但德国康斯坦茨大学的进化生物学家罗斯勒说，像跳蛛这样的生物并没有受到那么多关注，所以不知道它们是否有同样的睡眠。
