Crab Pinch Force

However the pinching force of this crab s chelae has not been previously investigated.

Crab pinch force. The researchers found that pinching force increased with body mass. Full episodes streaming free. For comparison a tiger bite has a force of. The researchers measured the claw pinching force of 29 wild coconut crabs from okinawa island japan.

In the present study we measured the pinching force of the chelae in 29 wild coconut crabs 33 2 120 g in body weight. This number was even more impressive. This amount 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.

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. 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. They can also use the powerful pincers to defend themselves. They can produce a pinch force of about 60 pounds.

The pinching force of the largest coconut crab is almost equal to the bite. But blue crabs don t just use their claws to find food. The maximum force ranged from 29 4 to 1 765 2 n and showed a strong positive correlation with body mass. Based on the correlation between pinching force and body weight the force potentially exerted by the largest crab 4 kg weight reported in a previous study would be.

The researchers explained that if human hands had the same strength a person could exert six tons of crushing force. Their sharp and strong grip can be quite painful as anyone who has ever been pinched by one can confirm. The limb will later regrow through a process called regeneration. 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.

Oka estimates that based on body size the largest known coconut crab could crunch with roughly 742 pounds of force. 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. Outrageous acts crab claws have strong muscles and their power is immense.
