6. Super Strong Dung Beetle
The strongest creature is not what you would expect, but the humble dung beetle – male Onthophagus taurus can pull a weight 1141 times greater than its own. It’s like a 90-kg man pulling a dozen school buses. And what uses this dung beetle its own power for? To impress the girls of course.
When a female dung beetle is in breeding season, it finds a great poo and digs a tunnel under it where it lays its eggs. The male who wants to have a generation must keep the tunnel and to repel all invaders. On success, it gets the right to be a father.
