Diving to depth is a typical behaviour observed in many aquatic mammals such as; whales, otters, seals, walrus and many others. Such mammals are well adapted at diving. The Weddell seal for example, is able to dive for periods of 80 minutes and more.
Oxygen comprises a large proportion of our atmosphere (21%) and has become a vital gas for many organisms on Earth. Without it our ability to produce energy (as ATP) via aerobic respiration fails.
