The animal known for having a trunk is the elephant. Elephants are the largest land animals and possess a distinctive elongated trunk, which is a fusion of their upper lip and nose. This remarkable appendage is incredibly versatile; it is used for a variety of tasks, including drinking, feeding, grasping objects, and social interaction. Elephants use their trunks to communicate with each other, express emotions, and even lift heavy objects. These intelligent creatures are known for their strong social bonds and complex behaviors, making them a fascinating subject of study in both wildlife and conservation efforts.
