Question

How does the morphology and function of the pedipalps differ between scorpions and spiders?

Answer 1

The pedipalps, or palps, which in arachnids function as an organ of touch, constitute the second pair of appendages.

morphology

In spiders the pedipalps are elongated leglike structures.

in scorpions they are large chelate, prehensile organs.

function

Spiders - Pedipalps are used by male spiders to transfer sperm to female spiders. In fact, you can usually distinguish a male spider from a female because of the male's enlarged pedipalps. All arachnids have pedipalps, but they often look quite different than spider pedipalps

Scorpions - The pedipalps originate in the second segment and terminate in pincers. Pedipalps are used for a variety of purposes, including prey capture, defense, courtship, and burrow excavation.
