How the coconut breaks
Thecoconut crabdoes not open coconuts with one swipe! Thesecrabsin addition to climbing trees, they have developed a technique for opening coconuts!
When the coconut is still wrapped in its "husk", the crab will use its claws to tear off the outermost (and tender) layers of the coconut. The palm crab operates near the three germination pores, these are those three small circles visible on the end of the coconut.
With the smallest tongs, the coconut crab opens one of those pores and from here it will begin its coconut opening work. After making a small hole, the crab is able to pull away the pulp of the coconut without breaking or completely opening the hard outer part.
Only adult crabs are able to break the hardest nut into small pieces to allow for easier consumption.

Of course, by the strength of hisclawsit cannot be considered a harmless animal but it does not spontaneously attack humans.
