“They’ve been shifting the frequency. They’ve been shifting the pitch to be lower each year. And that shift in pitch has resulted in song that is now about 30 percent lower than it was in the 1960s,” he says. He says the change is happening in blue whale colonies all over the world.

Seeing the Songs of Whales Acoustics engineer Mark Fischer has created a way to visualise whalesongs. This is Fischer’s representation of the low-frequency humpback whale’s mating song (audio here) with visualization going counterclockwise. NewScientist Slideshow here and article here.

The Origin of Big “In order to make lunge-feeding work, you have to have a really big mouth to capture enough water in one gulp. But in order to have a big mouth, you need a big body. And in order to keep that big body running, you need to get a lot of food. And in the very act of getting that food–diving deep, lunging open-mouthed, and then pushing a school-bus-sized volume of water forwards–requires a lot of energy on its own.” The Loom, Discover
