palp

(pălp)
n.
One of a pair of elongated, often segmented appendages usually found near the mouth in invertebrate organisms such as mollusks, crustaceans, and insects, the functions of which include sensation, locomotion, and feeding. Also called palpus.

pal′pal (păl′pəl) adj.

palp

a type of appendage associated with the head of invertebrate animals, usually in the mouth region, which has a tactile function. In some crustaceans, palps perform a locomotory function and in others are associated with feeding, as they are in bivalve molluscs where they produce feeding currents. In insects, palps are found on the first and second maxillae, where they are thought to be associated with olfaction.
