Meet the Coconut Crab.The delicious but rare Coconut Crab (Birgus latro) is reported to be the largest land-livin g arthropod in the worldThe Coconut Crab (Birgus latro) is the world's largest land-crab, often reaching 5kg. (for our American friends, that is just over 11lbs!)
Adult Coconut Crabs usually live within a few hundred metres of the shore, although they sometimes wander inland more than a kilometre. Years ago a researcher met a large blue one on the summit of Mount ‘Ikurangi(485m elevation and about 2.5km from the shore).
