Stylet (anatomy)
A stylet is a hard, sharp, anatomical structure found in some invertebrates. For example, the word stylet or stomatostyle is used for the primitive piercing mouthparts of some nematodes[1] and some nemerteans. In these groups the stylet is a hardened protrusible opening to the stomach.
The mouthparts of tardigrades, diptera and aphids[2] are also called stylets.[3]
The stylet is adapted for the piercing of cell walls, and usually functions by providing the operative organism with access to the nutrients contained within the prey cell.
