What specific anatomical feature constitutes the formidable tusks observed on an adult wild boar?

Elongated, continuously growing lower canine teeth

The impressive tusks that characterize adult wild boars are not simply decorative weaponry; they are a specialized dental adaptation derived from the lower canine teeth. These teeth possess the unique characteristic of continuous growth throughout the animal's life. While both male and female boars possess these tusks, they become significantly larger and more pronounced in the males. In boars, the sharp points curve upward markedly, making them highly visible. These tusks serve dual primary functions: they are essential tools used defensively when the animal feels threatened, and they play a critical role in dominance displays, especially during the mating season when males establish hierarchy to gain breeding rights. The continuous growth ensures they remain effective instruments despite wear and tear from foraging and fighting.
