The Hercules Beetle:
The Strongest Animal on Earth.
Whoa! You're probably thinking the strongest creature on earth is only a bug that fits in the palm of your hand? What about the largest living land mammal? You'd think something as massive as an elephant would be able to carry way more weight than a little insect. Yes, it's true. An elephant can carry a lot more weight than a rhinoceros beetle, but the definition of strength we're using here is one of proportional strength. A huge African elephant can carry up to 25% of its own weight on its back. The Hercules Beetle can carry up to 850 times its own weight. There's NO CONTEST. That would be like an elephant carrying 850 elephants on its back.
