Crab Pinch Force

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.

Crab pinch force.

And if threatened a crab may break off claw or leg to try to escape predators. The pinching force of the largest coconut crab is almost equal to the bite. For comparison a tiger bite has a force of. This number was even more impressive.

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. Based on the crabs maximum. Their sharp and strong grip can be quite painful as anyone who has ever been pinched by one can confirm. 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 maximum force ranged from 29 4 to 1 765 2 n and showed a strong positive correlation with body mass. This amount of force. But blue crabs don t just use their claws to find food. Oka estimates that based on body size the largest known coconut crab could crunch with roughly 742 pounds of force.

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 researchers found that pinching force increased with body mass. 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. The researchers explained that if human hands had the same strength a person could exert six tons of crushing force.

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. They can also use the powerful pincers to defend themselves. In the present study we measured the pinching force of the chelae in 29 wild coconut crabs 33 2 120 g in body weight. The range of their relative pinching force was greater than the maximum force of any animals within their body size range.

They can produce a pinch force of about 60 pounds. Full episodes streaming free. However the pinching force of this crab s chelae has not been previously investigated.
