Detailed explanation-1: -A lung capacity of up to five thousand litres and an exhalation that reaches speeds of over 600 kilometres per hour means sighting the blow of a Blue Whale is unmistakable. Exhaling 90% of their lung capacity, the Blue Whale will surface to breath every 8-12 minutes in the Perth Canyon when feeding.
Detailed explanation-2: -It lasted 222 minutes and broke the record for diving mammals. Other whales can also hold their breath for a very long time. A sperm whale can spend around 90 minutes hunting underwater before it has to come back to the surface to breathe.
Detailed explanation-3: -That clip was produced using real data that scientists collected a few years ago from a blue whale in Monterey Bay, California. The heart beat slowly when the animal dived, but when it came to the surface to breathe, the rate picked up dramatically, reaching as fast as 37 beats per minute.
