How do seals and sea lions hold their breath for so long?
AnimalsMammals
Quick Answer
They store extra oxygen in blood and muscles, and can slow their heart rate to conserve it underwater.
The Full Story
Marine mammals such as seals and sea lions are diving specialists. They have large blood volumes, high levels of oxygen-binding proteins in muscles, and the ability to reduce heart rate during dives. This allows them to stretch a breath across long underwater trips. Some species can dive to impressive depths and remain submerged for many minutes at a time.
