.Behold the largest land-living arthropod in the world, the coconut crab (Birgus latro) doing his morning rounds.
Known for their ability to crack
coconuts with its strong pincers and eat the contents (go figure that p.s.i), he's probably at
the limit of how big terrestrial animals with exoskeletons can get
under the prevailing conditions. Unlike other crabs, their body is divided into four
regions; the cephalic lobe, forepart, trunk, and opisthosoma.
And should you have the misfortune to get pinched by one of these giants (assuming you’re still conscious), you’d do well to remember this cool-headed advice from Victorian naturalist Thomas Hale Streets:
"It may be interesting to know that in such a dilemma a gentle titillation of the under soft parts of the body with any light material will cause the crab to loose its hold."
Tickle it as you scream...then run.
