What is Pedipalp?
[[Image:Pedipalp in green.svg|thumb|Drawing of [[whip scorpion]] with pedipalps in green]] '''Pedipalps''' are the two [[appendage]]s on the front of a [[spider]]'s head. Other [[arachnid]]s, and [[chelicerate]]s that are not arachnids also have pedipalps. Some spiders seem to have ten [[leg]]s and not eight, because these pedipalps look like an extra pair of legs. The pedipalps are used rather like [[arm]]s. Spiders often use them to hold [[insects]] (for example [[cricket]]s) for them to eat. [[Male]] spiders also use pedipalps for [[mating]]. The male spiders make some [[silk]], put [[sperm]] onto the silk, and then put their pedipalps into the sperm. The pedipalps then hold the sperm, and the spider can use it to mate with a [[female]] by putting them inside her [[epigynum]]. == Diversity of pedipalps == The pedipalps of all chelicerates vary: [[Ricinulei]], [[Thelyphonida]], [[Amblypygi]], some [[Opiliones]], [[Schizomida]], [[scorpion]]s and [[pseudoscorpion]]s all have theirs as pincers, with the Amblypygi's being their entire pedipalps shaped like mantids. The [[Palpigradi]]'s pedipalps have some of the strangest roles of arachnids as they use theirs for locomotion. The pedipalps of [[Solifugae]] act as [[antenna (biology)|antenna]]e. == Other websites == *[http://lymphocytes.741.com/pedipalps.html Close-up view of pedipalps on a large spider] {{Webarchive|url=https://web.archive.org/web/20041024054942/http://lymphocytes.741.com/pedipalps.html |date=2004-10-24 }} {{Biology-stub}} [[Category:Animal anatomy]] [[Category:Arachnids]] <!-- interwiki -->
