Fight for your lefts

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, while its beefy right pincher is useful for grappling with other crabs, the horned ghost crab uses its left claw for precision work like bringing food to its mouth, as a human southpaw does. (Admittedly, there is no evidence to suggest they use it for writing or playing golf.)
