OKINAWA, Japan, Nov. 23 (UPI) -- Keep your fingers away from coconut crabs. According to new research, the species pinches with the greatest force of all crustaceans.
Scientists measured the pinching force generated by 29 coconut crabs found on the island of Okinawa in Japan. They used the numbers to calculate the largest potential force based on the maximum size and weight of mature coconut crabs.
