The horn of the male is not used for protection but rather for the occasional battle with another male over a feeding site. The victorious male with the feeding site can then often attract a mate. Female Rhino Beetles have no horns. The females are quite plain and less frequently seen. Rhinoceros beetles are the strongest animals on the planet, proportionally. They can lift up to 850 times their own weight. To put this into perspective, if a human of average he
