It"s International Left-Handers 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.)
