Do spiders sleep? Study suggests they may snooze like humans

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

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.

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.

Their findings were published Monday in the journal Proceedings of the National Academy of Sciences.

Jumping spiders are cute.

I wonder what they dream about. Their prey and predators?

The big one that sits on your ceiling above your bed at night probably does…

I thought everyone knew spiders dreamed? People are so arrogant to assume so little of the world around them.
