The Strongest Animals in the World
From dung beetles to elephants, discover which animals pack the most power for their size and how scientists measure animal strength.
Animals come in every size imaginable, but pound for pound, some of the smallest creatures on Earth are also the strongest. This guide breaks down what “strength” actually means in the animal kingdom, and ranks the standout performers.
How Scientists Measure Animal Strength
Strength can be measured in a few different ways:
- Absolute strength – the total force or weight an animal can move, regardless of its own size.
- Relative strength – strength compared to body weight, which is where the smallest animals often dominate.
- Bite force – measured in newtons or pounds per square inch (PSI), used to compare predators.
Relative strength is why a tiny insect can outperform an elephant when body size is factored in.
Absolute Strength Champions
Larger animals tend to win when it comes to raw, absolute power.
- African elephant – can lift roughly 9,000 lbs (4,000 kg) with its trunk.
- Saltwater crocodile – has the strongest bite force of any living animal, estimated at over 3,700 PSI.
- Gorilla – capable of lifting close to 10 times its own body weight.
Relative Strength: The Real Champions
When you compare strength to body size, insects dominate the leaderboard.
1. Dung Beetle
The dung beetle can pull over 1,000 times its own body weight, making it the strongest animal on Earth relative to size. Researchers at Queen Mary University of London found the strongest males could pull 1,141 times their body weight, equivalent to a 70kg person lifting six double-decker buses. Scientists believe this strength evolved from underground battles between males over mates and dung resources.
2. Rhinoceros Beetle
Rhinoceros beetles can carry roughly 850 times their body weight, using their signature horn to flip rivals during battles for territory.
3. Leafcutter Ant
Leafcutter ants can carry leaf fragments up to 50 times their own body weight, using specialized jaw muscles built for repetitive, high-load lifting.
Why Relative Strength Matters
Smaller animals need proportionally more strength to survive, whether that means moving food many times their size, digging shelters, or defending territory against larger predators. Studying these mechanics has even influenced robotics and materials engineering.
Frequently Asked Questions
Is an ant stronger than an elephant? Relative to body weight, yes. An elephant is far stronger in absolute terms, but an ant can carry a much larger multiple of its own body weight.
What animal has the strongest bite force? The saltwater crocodile currently holds the record for the strongest measured bite force among living animals.
Understanding animal strength shows just how varied survival strategies can be, from raw power to remarkable efficiency at a tiny scale.
