Blue whales, the ocean’s biggest singers, have suddenly gone quiet—and scientists are freaking out. Turns out, their favorite food (krill) basically vanished after a massive marine heatwave, leaving them too hungry to sing. Humpbacks kept singing (they eat more stuff), but blue and fin whales just went silent, spending all their energy searching for food. Researchers say climate change is making things worse, and if whales can’t find food, the whole ocean ecosystem could be in trouble. Wild, right? #Science #BlueWhales #ClimateChange
