How does a spider use their pedipalp?

Spiders use their pedipalps primarily for two functions: sensory perception and reproduction. These appendages, located near the mouth, are equipped with numerous sensory hairs that help spiders detect vibrations and chemical signals in their environment. In male spiders, pedipalps also play a crucial role during mating, as they are often adapted to transfer sperm to the female. Overall, pedipalps enhance a spider's ability to interact with its surroundings and engage in reproductive activities.
