US MegaBots beat Japan in world’s first-ever big robotic showdown
In this screenshot from the video, an enormous coconut crab pinched and ultimately ate a sleeping seabird. These crabs have a pinch pressure akin to a lion’s chunk pressure.

Even animals should be alert once they sleep. An enormous coconut crab devoured a sleeping seabird, a video exhibits.
In the video, an enormous crab from the Indian Ocean will be seen attacking and consuming an grownup red-footed seabird sleeping on a low-lying department.
Giant Coconut Crabs
Growing to greater than three toes, coconut crabs or Birgus latro are the world’s largest land dwelling arthropods. Named after their energy of opening coconuts, these crabs have armor-clad legs and big claws that may carry as a lot as 61 to 66 kilos of weight regardless of weighing solely about eight to 9 kilos when absolutely grown.
These crabs, as a substitute of snapping their claws, apply a crushing pinch pressure. A earlier examine confirmed that the terrestrial crabs have a pinch pressure of 750 kilos. For reference, people have a average chunk energy of 265 kilos. The crab’s pinch pressure is akin to that of a lion’s chunk pressure.
The mighty claws of those arthropods are a results of evolution. The stripping of their shells led them to develop a calcified stomach as they grew bigger. Their claws are fairly sturdy, enabling them to climb bushes just like the spider-like crab species discovered to dwell in bushes.
Giant coconut crabs are omnivores. They eat fleshy fruits however may devour meat when it’s out there, as is on this case.
Altering The Ecology Of Islands
The video, recorded a couple of yr in the past by Mark Laidre, a biologist from Dartmouth College, confirmed the preying habits of big coconut crabs whereas observing the crustacean within the Chagos Archipelago. The crab snatched the unsuspecting chicken, snapped its wings and clawed by its physique. About 20 minutes into the video, 5 extra coconut crabs swarmed the chicken.
Laidre’s observations, which he wrote in a paper revealed within the Frontiers in Ecology and the Environment in Nov. 1, led him to conclude that elements of islands inhabited by extra coconut crabs have fewer nesting birds. He famous that coconut crabs can’t transfer freely so there are areas within the island the place they’re aplenty.
“They’re not belligerent. They’re curious,” shared Laidre in an interview. “They’re not coming and jumping and trying to attack you. Coconut crabs more should fear humans.”
In 2014, residents of Hawaii’s Salt Lake neighborhood caught an enormous coconut crab. Coconut crabs will not be native to Hawaii. In reality, possession of this crustacean is a Class C Felony and constitutes a three-year imprisonment and a superb of $200,000.
