Mandible
A paired jaw-like mouthpart found in many arthropods, including insects and crustaceans. Mandibles cut, crush, or handle food.
Insect mouthparts: The structures insects use to obtain and process food, including mandibles, maxillae, and the labium. Mandibles form one part of this coordinated feeding apparatus.
Arthropod: An invertebrate animal with a segmented body, jointed appendages, and an external skeleton. Mandibles are appendages of arthropods, modified for feeding.
Termite soldier: A caste member of a termite colony specialized for colony defense. Soldier termites can have enlarged mandibles adapted for biting or combat.
Arthropod head segmentation: The organization of arthropod head regions from fused segments bearing specialized appendages. Mandible position and identity are interpreted through this segmented body plan.
Mandibulate mouthparts: An arthropod mouthpart arrangement centered on paired mandibles for biting or chewing. This arrangement shows how mandibles operate within a complete mouthpart system.
Head capsule: The hardened outer structure enclosing an insect’s head and supporting sensory and feeding organs. Mandibles attach to and move from this structural framework.
Ant mandible: A mandible of an ant, used in feeding, nest work, defense, or carrying objects. Ants demonstrate how one mouthpart can serve tasks beyond eating.
Mandibulata: A major arthropod grouping that includes myriapods, crustaceans, and hexapods. The group is defined in part by the presence of mandibles.
Insect chewing: A feeding mode in which insects use hardened mouthparts to cut and grind solid food. Mandibles supply the main cutting and grinding force.
Maxilla (arthropod): A paired arthropod mouthpart that manipulates food and often bears sensory structures. Maxillae handle food near the mandibles and complement their cutting action.
