Ogre-faced spiders, named for their massive eyes, hide during the day and hunt by night, dangling from Florida palm fronds and casting silk nets on insects on the ground and in the air. In addition to their incredible night vision, these spiders also can hear their predators and prey, researchers report in the journal Current Biology on October 29. Having no ears, the spiders use hairs and joint receptors on their legs to pick up sounds from at least 2 meters away. The results suggest that spiders can hear low-frequency sounds from insect prey as well as higher frequency sounds from bird predators.
