In an uncommon exercise in cetacean research, a team successfully placed a tag with electrodes on the back of a blue whale<\/a> to calculate its heart rate. The results are staggering: this medium-sized bull with a resting heart rate of around 15 beats a minute can lower it to as little as two! Two beats a minute! That\u2019s a drop of over 85%. In comparison, a human at rest has a heart rate of between 50 and 80 beats per minute and can subconsciously lower his or her pulse by as much as 25% when holding his or her breath. But how is the blue whale able to survive such a low heart rate and, especially, what are the benefits for the animal?<\/p>\n","protected":false},"excerpt":{"rendered":"
