Pedipalp

From the proximal end (where they are attached to the body) to the distal, they are: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus.

The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons (pincers) of great size, as in scorpions.

The pedipalps are distinctly raptorial (i.e., modified for seizing prey) in the Amblypygi, Uropygi, Schizomida, and some Opiliones belonging to the laniatorid group.

[citation needed] Pedipalps of spiders have the same segmentation as the legs, but the tarsus is undivided, and the pretarsus has no lateral claws.

Pedipalps contain sensitive chemical detectors and function as taste and smell organs, supplementing those on the legs.
