Maxillules

Maxillules are small, tooth-like structures found in the mouthparts of certain arthropods, particularly in insects and crustaceans. They are part of the mandibulate subphylum, which includes insects and their relatives. Maxillules are located on the maxillae, one of the paired mouthparts, and are used for manipulating food and other objects. They are typically found in chewing and biting mouthparts, where they help to grind and tear food. Maxillules are often used in conjunction with other mouthparts, such as mandibles and labium, to perform various functions. In some species, maxillules may also be used for defense or communication. The structure and function of maxillules can vary greatly among different species, reflecting their diverse ecological roles and adaptations.
