Nov 26, 2019, 7:18 PM. The sensor set by the scientists showed that in the deepest dives, the heart of the whale beat at an average rate of 4 to 8 times per minute, with a minimum of only 2 beats per minute. They say the data indicates a blue whale's heart is working at its maximum capacity when at the surface, and may explain why they have never evolved to be bigger, despite already being the largest mammal thought to exist. When mammals submerge, their bodies automatically begin to redistribute oxygen; The heart and brain are the ones that most demand oxygen, while your muscles, skin and other organs receive less. Upon reaching adulthood, the blue whale can be more than 30 meters long, more or less the length of two school buses parked one after the other. It takes a big heart to drive a beast of such size; and while this organ is not so large that a human can swim inside one of its arteries, as an urban myth says, the truth is that stranded whales have allowed hearts to recover up to 200 kilograms and the size of a golf cart . Environment News: Scientists have recorded the heart rate of the blue whale for the first time, and revealed surprising operating extremes of the heart that may limit t Using suction cups, biologists attached electronic sensors to a blue whale's left flipper to measure its heart rate. The maximum recorded was 37 beats per minute. (CNN) For the first time, scientists have recorded the heart rate of a blue whale, uncovering new information about the biology of the world's largest mammal. A typical blue whale is close to 30 meters (98 ft) in length and with a maximum recorded weight of 173 tonnes. 12000 Years Old Body of a Anunnaki King Found Completely intact?

The blue whale’s heart rate peaks between 25 and 37 beats per minute when it surfaces to breathe – then its pulse plummets to two beats per minute when it dives for food. For the first time, researchers have managed to record the heart rate of the blue whale; the largest animal that has ever lived on planet Earth . That’s about 50 percent lower than the researchers predicted. Video by Kurt Hickman With a lot of ingenuity and a little luck, researchers monitored the heart rate of a blue whale in the wild. The research team documented the rhythms thanks to a few suction cups that kept a heart rate monitor attached to a whale swimming and diving around California's Monterey Bay. The blue whale, also known as a sulfur-bottom whale, or by its Latin name, Balaenoptera musculus, is the largest animal known to have lived, with an average weight of … Encased in a neon orange plastic shell, a collection of electronic sensors bobbed along the surface of the Monterey Bay, waiting to be retrieved by Stanford University researchers. After measuring the heart rates of diving emperor penguins and captive whales, researchers from the University of Stanford decided to try to measure the heart rates of wild whales.
