In a global effort to understand whale communication, researchers have created a website asking people from around the world to match songs recorded from pilot and killer whales. The songs were recorded using suction-cup sensors that not only record the tagged animal’s songs, but also those of neighboring whales. Other questions on the website include distinguishing potential differences in the songs of short- and long-finned pilot whales and whether human sonar transmissions affect whale songs. This project is sponsored by Scientific American, Zooniverse, WHOI, TNO, University of Oxford, and The Sea Mammal Research Unit (SMRU) at the University of St Andrews.
