WASHINGTON - Using a bright orange electrocardiogram machine attached with suction cups to the body of a blue whale, scientists for the first time have measured the heart rate of the world’s largest creature and came away with insight about the renowned behemoth’s physiology.
“The blue whale is the largest animal of all-time and has long fascinated biologists,” said Stanford University marine biologist Jeremy Goldbogen, who led the study published in the journal Proceedings of the National Academy of Sciences. The researchers created a tag device, encased in an orange plastic shell, that contained an electrocardiogram machine to monitor a whale’s heart rhythm swimming in the open ocean. The device had four suction cups to enable them to attach it to the whale non-invasively.
