how long can arctic seals hold their breath

Arctic seals can hold their breath underwater for a range of about 15 minutes up to 90 minutes, depending on the species and activity. For example, ringed seals commonly found in the Arctic can hold their breath for around 45 minutes, while some other Arctic seal species can manage up to 90 minutes during deep dives. This remarkable breath-holding ability is supported by physiological adaptations such as large lungs, the ability to collapse lungs to prevent decompression sickness, slowed heart rate (bradycardia), and efficient oxygen storage in blood and muscles.
