“The pinching force of the largest coconut crab is almost equal to the bite force of adult lions,” Oka tells
Will Dunham at Reuters. “The force is remarkably strong. They can generate about 90 times their body weight.”
The pinch-force of the crab exceeds that of any other known crustacean, according to a
press release. If a human had the same pinch strength to body-weight ratio as the coconut crab, Oka says, they would be able to produce six tons of crush force. Among terrestrial animals and when adjusted for body size, the crab's size to crush ratio is second only to the bite of the saltwater crocodile,
which has a bite force that rivals T. Rex.
