Oh, the fish has that swim bladder, I think, to float without trying—like our bamboo baskets bobbing in the lake. But sharks... they must keep moving to breathe, which makes them seem so restless and hungry. Honestly, after watching that movie *The Shallows*, I just feel they move because they are always searching, always hunting. It’s why I get nervous even wading in Umiam Lake now—every dark ripple feels like a fin.
