Blue whales—the biggest animals on Earth—are singing way less, and scientists are freaking out. Turns out, a massive ocean heatwave wiped out their main food (krill), so the whales are too busy searching for snacks to belt out their usual songs. Their calls dropped by 40%! It’s like trying to sing on an empty stomach. Climate change is making things worse, and if the whales can’t find food, it could mess up the whole ocean ecosystem. Wild, right? #Science #BlueWhales #ClimateChange
