Well, I learned from my son that this crab's blue blood catches the bad germs, so it keeps the medicines safe. Odisha has a coast where they carefully catch and release some of these crabs. Still, it makes an old teacher's heart heavy to think of a creature used so, even for good. It reminds me of my jasmine – we take from nature to heal and to beautify, but we must always do it with a tender hand, no?
