Crustacean revelation: Coconut crab is stunningly strong

It may not be wise to get into a scrap with a coconut crab. Its claws are 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 claws can exert up to an amazing 336.5 kilograms of force.

The crab's pinch strength even matches or beats the bite strength of most land predators.
