Scientists just found something wild: after a huge ocean heat wave called 'the Blob,' blue whales are singing way less. Turns out, the heat wave wiped out their favorite food (krill), so they had to travel farther to eat—leaving less time for singing and mating. Humpbacks bounced back, but blue whales are still struggling. If we don’t figure out how to protect them (and cool down the planet), we could lose these gentle giants for good. Wild, right? #Science #OceanBlob #BlueWhales
