Until now, no one had managed to record the heart rate of a blue whale. But a team of U.S. researchers took the first recording of a blue whale's heart rate.
Led by Jeremy Goldbogen, assistant professor of biology at Stanford University, the team used a specialized tracking device equipped with electrodes and other sensors, which they attached via suction cups to a wild blue whale in Monterey Bay, California.
