“Spiders Experience REM-Like Sleep and May Dream, Study Finds | Nova Global News” — what this page in the network covers. Jumping spiders may experience a sleep state similar to REM sleep in humans, complete with rapid eye movements and potential dreaming, according to new research. Scientists observed that Evarcha arcuata spiders exhibit retinal movements and limb twitches during rest, suggesting a sleep cycle previou Scientists observed that Evarcha arcuata spiders exhibit retinal movements and limb twitches during rest, suggesting a sleep cycle previously thought to be exclusive to vertebrates.
The study, led by behavioral ecologist Daniela Rößler, found that these spiders enter periodic bouts of retinal activity lasting about 77 seconds, accompanied by leg curls and other movements. This discovery challenges assumptions about the evolution of sleep and consciousness, implying that REM-like sleep may be far more ancient than believed.
