Fight for your lefts

It's International Lefthanders Day, so why are we showing this horned ghost crab whose right claw is noticeably larger than its left? Well, we're calling this crab a lefty because while its beefy right pincher is useful for grappling with other crabs, it uses its left claw for precision work like bringing food to its mouth, as a human southpaw does. (Though to be fair, it's never been observed which claw these crabs use for writing or playing golf.)
