Scientists say they have solved the mystery of one of the most extreme adaptations in the animal kingdom: how marine mammals store enough oxygen to hold their breath for up to an hour.

The team studied myoglobin, an oxygen-storing protein in mammals' muscles and found that, in whales and seals, it has special "non-stick" properties.

This allowed the animals to pack huge amounts of oxygen into their muscles without "clogging them up".

Scientists from the University of Liverpool have published research that explains how marine mammals, including seals and whales, hold their breath for so long.

The research reveals how the oxygen-storing capacity of mammals muscles has been changed by millions of years of evolution.

The videos above show how a highly trained free-diver compares in breath-holding ability to a common seal.

And here we explore some of the most extreme examples of breath-holding in the animal kingdom and how they match up with record-breaking human free-divers.
