It may not be wise to get into a scrap with a coconut crab. Its claw is a mighty weapon.
Scientists on Wednesday said they measured the pinch strength of this large land crab that inhabits islands in the Indian and Southern Pacific oceans, calculating that its claw can exert up to an amazing 336.5 kg of force.
The coconut crab's pinch strength even matches or beats the bite strength of most land predators.
