Spiders can actually hear you coming.
New research from Cornell University found that spiders, specifically jumping spiders, can hear.
Spiders don't have eardrums, so researchers assumed they couldn't hear.
The new study found that the can hear via long trichobothria hairs on their legs.
Here's more from Slate:
For the hearing experiment, the scientists played a sound at the same frequency as the one produced by a mud dauber wasp, insects that prey upon jumping spiders. As soon as they did, the spider froze in place and looked around for the threat, and the electrodes registered a pronounced spike in activity in the brain’s auditory area. Jumping spiders, at least, can hear.
