Scientists have observed that blue whale songs have dropped by nearly 40%, a troubling shift in one of the ocean’s most iconic sounds. For the largest animals on Earth, vocalization isn’t random—it’s closely tied to feeding success and overall energy levels. When krill—their primary food source—is abundant, blue whales sing more frequently and for longer periods. But when food becomes scarce, they conserve energy, and their songs grow quieter. The recent decline in vocalizations suggests whales

What do whales sound like underwater? Let’s dive in and listen! Listen to different whale sounds and see what they look like on a spectogram, which is a way to visually display sound. #WorldWhaleDay | NOAA Fisheries Service

The sequences of clicks they use to communicate and identify one another are called codas, and it’s thought that each whale has their own unique vocalization pattern. Their clicks can be louder than 200 decibels—that’s like standing near a rocket at takeoff. Though sound travel

First analytical output of a humpback whale song processed through my birdsong analysis framework. It worked flawlessly without any adaptation of the pipeline, and the whale vocalization unfolds into coherent geometric structures, a truly exciting starting point for further explorative work. A big thank you to Franck Eckler @geographe_photo and @geographemarineresearch for sharing these amazing recordings and their interest in my research. We're very excited and looking forward to what comes nex
