Do Spiders sleep?

Spiders don’t sleep in the same way humans do.; they, too, have a daily pattern of activity and rest. However, not possessing eyelids means that spiders can’t close their eyes for sleep; instead, they decline their movement levels and reduce their metabolic rate to store energy.

Spiders are exceptionally resourceful, especially web-building spiders who rely on food coming to them whenever possible. To avoid becoming a meal themselves, many spiders take their chances while hunting at night when most predators, such as birds, are less active and less likely to catch sight of them. This helpful ability has been an evolutionary asset for these creatures.

Despite the lack of studies concerning spider sleep, scientists have determined that spiders possess circadian rhythms, which involve daily intervals of rest and motion. The activity duration is distinct for each species; some are more energetic at night, while others prefer daytime activities.

To stay alive in cold climates, they enter a state of hibernation or suspended animation, where their metabolism dramatically decreases until it gets warmer.

What does a sleeping spider look like?

During hibernation, spiders tuck in their legs and slow their metabolic rates to survive without eating for extended periods. You can detect if a spider is sleeping by noticing its tucked-in position – usually lying on its back or in an awkward pose with the limbs tucked away means that it’s dead. Additionally, specific triggers such as circadian rhythms or cold temperatures can evoke a comatose state within these eight-legged creatures.

While you slumber soundly, spiders are busy constructing and repairing their webs at night. Despite having numerous eyes, these arachnids don’t have perfect vision, so hunting during late hours is not a problem. During the day, they can relax on their web or in a secure nearby area. Some orb weavers take things one step further by creating an entirely new web each evening before consuming it upon sunrise!

Whereas some spiders prefer to hunt without weaving a web, jumping spiders are equipped with extraordinary vision, which aids them in attacking their prey. These active creatures tend to be more visible during the daytime when sufficient light and darkness allow them to rest by suspending themselves on strands of silk threads.

To date, the closest humans have gotten to revealing sleep in spiders (Araneae) involves documenting circadian activity and resting postures. For example, jumping spiders are occasionally found inside silken havens, standing or hanging upside down from a silk thread for hours without moving.

This quiet “sleep” mode is punctuated by an active state featuring unique posture changes, twitches, and rapid retinal movements.

With their legs conventionally drawn up while hanging or slightly curled in a fashion suggesting muscle relaxation, spiders have long been associated with an appearance of slumber. Even more intriguingly, the spinnerets, abdomen (the posterior region of the body), and bent limbs can sporadically twitch – leading to speculation that they enter REM sleep-like states as seen in vertebrates.

Although this behavior has not been tested using classic measures for defining sleep patterns, authors are taking great care to refer to it only as “REM sleep-like.”
