Most elephants favor one tusk over the other, similar to human handedness. The preferred tusk is used more frequently for digging, stripping bark, and moving objects. Over time, this tusk becomes shorter and more worn. Researchers can identify dominant tusk use by wear patterns alone. This preference remains consistent throughout life.
It matters because tusk dominance affects feeding efficiency and survival. Losing a dominant tusk can significantly impact an elephant’s daily behavior.
It also helps researchers identify individuals and understand injury impacts. Small details reveal big behavioral truths.
Studies show right-tusk dominance is slightly more common than left. Some elephants even compensate behaviorally if their dominant tusk is damaged.
