(重定向自Palpus)
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates– a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs.
