A blue whale's heartbeat was recorded for the first time

Nov 27, 2019 15:23 IST

Researchers from the University of Stanford have recorded the heart rate of a blue whale for the first time and the results are fascinating.

Using suction cups, biologists attached electronic sensors to a blue whale's left flipper to measure its heart rate. 

They found that a whale lowered its heart rate to as low as 2 beats per minute during a dive for food, while the mammal's maximum heart rate went up to 25 and 37 beats per minute, at the surface when it was breathing and restoring oxygen levels.

Scientists say these studies may have important implications for the conservation and management of endangered species like blue whales.
