Proboscis
A proboscis is an elongated tubular mouthpart used by many animals to feed or sense. Its form and function vary across animal groups.
Butterfly proboscis: A coiled, tube-like mouthpart that butterflies extend to drink liquid food. Its flexible tube uncoils to reach nectar and other liquids.
Mouthpart: An anatomical structure that an animal uses to obtain or process food. Proboscides are specialized mouthparts, though some also serve sensory roles.
Hawk moth: A moth in the family Sphingidae, often equipped with a long, coiled proboscis for feeding on nectar. Some species reach nectar deep inside flowers with exceptionally long mouthparts.
Beak: A hard external structure around the mouth, found in birds and some other animals. A beak handles food without forming the elongated tube characteristic of a proboscis.
Mosquito mouthparts: A bundle of elongated mouthparts that mosquitoes use to pierce tissue and take blood or plant fluids. Its piercing elements show how a proboscis can penetrate a surface.
Insect mouthparts: The varied structures insects use to bite, chew, pierce, suck, or otherwise handle food. Insects have diverse mouthparts, including several forms called proboscides.
Mosquito: A slender-bodied fly in the family Culicidae; females of many species take blood meals. Its proboscis is a familiar example of a specialized blood-feeding apparatus.
Tongue: A muscular or otherwise specialized organ in the mouth, often used for tasting and moving food. A tongue can reach or collect food but is not necessarily a tubular mouthpart.
Elephant trunk: A muscular, elongated organ formed by the elephant’s nose and upper lip. It combines food handling and sensing in a highly mobile proboscis.
Animal feeding: The behaviors and anatomical adaptations animals use to acquire and consume food. Feeding demands shape the length, flexibility, and function of proboscides.
