Veronica's Random Dose - The Coconut Crab.
Found in just a few places around the world (due to it's endanger from extinction), lives the world's largest land-living arthropod - the coconut crab (also known as the robber crab or palm thief since some have been rumored to steal shiny objects from individuals homes and tents).
Referenced to be about 40 cm (16 in) in length, and weighing up to 4.1 kg (9.0 lb), this nocturnal specimen comes out at night to forage for; among other things; coconuts!
Ingeniously, the coconut crab finds several ways to consume the contents of a coconut.
1.) Eyewitnesses have watched as this unique arthropod cut a coconut down to a husk nut; climb a tree; then proceed to drop the husk nut to the ground where it breaks apart; and then climb down from the tree to consume the contents.
2.) Others have watched as the coconut crab simply pounds a coconut against a rock until it cracks open; allowing it to consume it's contents (it is the front-most pair of legs that consist of large claws used to open coconuts, these claws can lift objects up to 29 kg [64 lb]).
Although the coconut crab is known for it's ingenuity, unlike it's peers, the coconut crab lacks the ability to swim. No matter, the coconut crab has learned to adapt so well, that it can live for over 30 years!
