Spiders and scorpions are members of one chelicerate group, the arachnids.[14] Scorpions' chelicerae have three sections and are used in feeding.[15] Spiders' chelicerae have two sections and terminate in fangs that are generally venomous, and fold away behind the upper sections while not in use. The upper sections generally have thick "beards" that filter solid lumps out of their food, as spiders can take only liquid food.[13] Scorpions' pedipalps generally form large claws for capturing prey,[15] while those of spiders are fairly small appendages whose bases also act as an extension of the mouth; in addition, those of male spiders have enlarged last sections used for sperm transfer.[13]
