The elephant is a large mammal known for its distinct features, such as its TUSK, EAR, and TRUNK. The term 'elephant feature' can refer to any of these three characteristics. The TUSK is a long, curved tooth that protrudes from the mouth of the elephant and is made of ivory. The EAR is a large, floppy appendage on either side of the head. Finally, the TRUNK is a long, flexible snout used for breathing, smelling, and grasping objects.
