(CNN)Spooky season is here -- so let's talk about spiders.
Ogre-faced spiders are believed to have the largest eyes of all known spider species, and they are known for their reported ability to see in the dark 2,000 times better than humans. That formidable eyesight, however, is just one of the sensory tools these arachnids can use when they hunt for food, a new study has revealed.
These spiders can hear, too. In fact, ogre-faced spiders can hear both low frequency and high frequency sounds, according to the study, which was published Thursday in the journal Current Biology.
Using receptors on their legs, these spiders can detect sounds from at least 6.5 feet from the source, and are sensitive to frequencies up to 10 kilohertz, the research team said.
Through laboratory tests and observations in the field, the scientists showed that auditory stimuli in the same low frequency range as the wing beats of moths, mosquitoes and flies prompted the spiders to perform a "backward strike," one of their signature hunting moves.
This, according to the researchers, showed that the spiders use auditory cues to detect and capture flying prey.
"These spiders are a gold mine of information that have just gone untapped for a really long time," said study coauthor Jay Stafstrom, a postdoctoral researcher in neurobiology and behavior at Cornell University.
"The visual capabilities that they possess are off the map, and now, showing they can hear quite well, I think there's a lot more to understand about them going on in the future."
Like 'Jekyll and Hyde'
Ogre-faced spiders are tropical critters found all over the world, including in the US, where they are present in Southern states like Florida.
You are unlikely to have noticed them in your backyard though, as they spend the day hours camouflaging as plant fronds, and only become active at night.
"The metaphor is Jekyll and Hyde," senior study author Ronald Hoy, a professor of neurobiology and behavior at Cornell, told CNN.
"By day, this creature acts dead. By night, this creature kills, preys, hunts. Its personality is set by the sun or the moon."
Unlike other spiders that build a web that captures their food, ogre-faced spiders are net casters and hunt in a more active, rather dramatic fashion.
They build an A-shaped frame web from which they dangle upside down at night, and use a net they hold with their legs to trap prey when it's within reach.
