What weapons do stag beetles have?

Stag beetles possess large, elongated mandibles that resemble antlers, which they use primarily for fighting other males during mating competitions. These mandibles can be quite powerful and are employed to grasp or wrestle opponents. Additionally, their strong jaws help them to crush and consume wood, which is part of their diet as larvae. While they are not used for defense against predators, their impressive size can deter some threats.
