Crab pinch force.

The pinching force of the largest coconut crab is almost equal to the bite. The researchers measured the claw pinching force of 29 wild coconut crabs from okinawa island japan. For comparison a tiger bite has a force of. Oka estimates that based on body size the largest known coconut crab could crunch with roughly 742 pounds of force.

Although the highest force measured was already an impressive 400 pounds the force of each crush was correlated with body size to determine the maximum force a coconut crab could use. I saw monster mike86 post hundreds of land crabs on his instagram so i took my friend franklin rawwfishing down there to film a sick catc. The limb will later regrow through a process called regeneration. However the pinching force of this crab s chelae has not been previously investigated.

The researchers found that pinching force increased with body mass. The maximum force ranged from 29 4 to 1 765 2 n and showed a strong positive correlation with body mass. Their sharp and strong grip can be quite painful as anyone who has ever been pinched by one can confirm. Based on the crabs maximum.

The range of their relative pinching force was greater than the maximum force of any animals within their body size range. While crabs all have fierce looking pincers and some of the bigger ones would very much hurt and could cause some bad lacerations with their claws all crabs are still relatively small and fragile animals with very little in terms of mass behind their claws. This number was even more impressive. In the present study we measured the pinching force of the chelae in 29 wild coconut crabs 33 2 120 g in body weight.

Oka and his crew found a coconut crab s pinching ability correlates with its body mass with the largest mustering a pinching force of 3 300 newtons. The researchers explained that if human hands had the same strength a person could exert six tons of crushing force. Outrageous acts crab claws have strong muscles and their power is immense. This amount of force.

They can also use the powerful pincers to defend themselves. They can produce a pinch force of about 60 pounds. But blue crabs don t just use their claws to find food.
