“Animals that function at physiological extremes can help us understand the biological limits of size,” said lead author Jeremy Goldbogen, an assistant professor at Stanford University in California. (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. Goldbogen has spent decades studying blue whales by sticking data loggers on their back. BOSTON: 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 the size of the largest animal on the Earth. Scientists already knew that the pulse of these cetaceans decreased in the aquatic environment. The maximum recorded was 37 beats per minute. “At that time the heart of the whale was working near its physical limit,” the authors add. They say they tagged a blue whale in Monterey Bay and, after monitoring the massive mammal, were able to successfully hear and capture its beating heart. The measurement suggests that blue whale hearts are operating … Scientists record a blue whale’s heart rate for the first time and find it is already working to its limit The researchers say this could explain why the blue whale has not evolved to grow bigger.

Nov 26, 2019, 7:18 PM. At the very bottom of one of those dives, the whale's heart rate increased to about 2.5 times the minimum and then dropped again, only increasing when the whale began to surface. 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. During the dives, the whale’s heart has brutal ups and downs, pumping from 34 times per minute on the sea surface to only 2 per minute at the deepest depths – between 30 and 50% slower than expected to be recorded. Researchers found that when the blue whale is diving for food, its heart rate lowered to as little as two beats per minute. When a blue whale feeds, it skips several heartbeats, sometimes up to 30. this is what a team of marine biologists has discovered after being able to record the heartbeat of a blue whale, on the coast near California. The biggest heart in the world beating in the largest mammal. According to the data collected, the blue whale's highest heart rate was recorded at the surface - between 25 and 37 beats per minute. For the first time, the heartbeat of the blue whale has been recorded. According to the data collected, the blue whale's highest heart rate was recorded at the surface - between 25 and 37 beats per minute. The first-ever recording of a blue whale's heart rate reveals why they win the size game -- and why they aren't even bigger. This allows animals to stay underwater for longer with a single inhalation, resulting in a lower than normal heart rate.

Blue Whales can survive with two beats per minute in the ocean depths and now for the first time heartbeat of a blue whale is recorded. Scientists recorded a blue whale's heartbeat for the first time, and found that the world's largest creatures can survive on just two beats per minute while diving for food. Using suction cups, biologists attached electronic sensors to a blue whale's left flipper to measure its heart rate. Researchers also said the whale's highest heart rate came close to beating predictions, but their lowest heart rate was up to 50 per cent slower than expected. 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. Stanford researchers report first recording of a blue whale’s heart rate With a lot of ingenuity and a little luck, researchers monitored the heart rate of a blue whale in the wild. According to the new study published in PNAS, the simple act of opening the mouth to eat takes the heart of the cetacean to its physical limits, something that could explain why there are no creatures larger than the blue whale on the planet. Sperm and bowhead whales go on even longer dives than blue whales, so what does this new data signal about their heart rates? That’s about 50 percent lower than the researchers predicted. The team suction-cupped a pulse monitor to the back of a blue whale off the California coast, in order to achieve this new data. 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. The lead researchers on the project say the ability to study a blue whale's heart rate opens the door to a much greater understanding of how they are able to perform some of the most amazing feats of diving and exercise. Researchers say that's because the mammal is breathing and restoring oxygen levels when it comes above water. Save my name, email, and website in this browser for the next time I comment.
