Largest land-invert in the world

WOW!!

are they legal to keep as a pet?
 
Holy Cow! Where are these? Want to know so I can make sure I never meet one in a dark alley!

The coconut crab, Birgus latro, is the largest land-living arthropod in the world and is probably at the limit of how big terrestrial animals with exoskeletons can get under the prevailing conditions

It is also called the robber crab or palm thief, because some coconut crabs are rumored to steal shiny items such as pots and silverware from houses and tents
