Crab Pinch Force

The researchers explained that if human hands had the same strength a person could exert six tons of crushing force.

Crab pinch force. Their sharp and strong grip can be quite painful as anyone who has ever been pinched by one can confirm. And if threatened a crab may break off claw or leg to try to escape predators. 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.

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. 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. In the present study we measured the pinching force of the chelae in 29 wild coconut crabs 33 2 120 g in body weight.

For comparison a tiger bite has a force of. 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. This amount of force. The researchers measured the claw pinching force of 29 wild coconut crabs from okinawa island japan.

They can also use the powerful pincers to defend themselves. However the pinching force of this crab s chelae has not been previously investigated. But blue crabs don t just use their claws to find food. Given that the largest coconut crabs weigh around 9 lbs the researchers calculated that the biggest of the species could generate a pinch with a force of 3 300 newtons greater than that of any.

The limb will later regrow through a process called regeneration. Oka estimates that based on body size the largest known coconut crab could crunch with roughly 742 pounds of force. This number was even more impressive. They can produce a pinch force of about 60 pounds.

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.
