What is probiscus?

A proboscis is an elongated, flexible feeding structure that some animals possess, primarily used for sucking or feeding. It is commonly found in insects, such as butterflies and mosquitoes, where it functions like a straw to draw in liquids. Additionally, some mammals, like the tapir, have a proboscis that serves various purposes, including foraging and grasping. In general, the term can refer to any elongated appendage that aids in feeding or sensory functions.
