Scientists say they have solved the mystery of how marine mammals like seals and whales can store enough oxygen to hold their breath for up to an hour.

The team found that the oxygen storing protein in sea mammals' muscles has special non-stick properties.

This means the special non-stick protein can be packed into their muscles in huge quantities without clogging them up.

It's hoped the findings will help with research into diseases that affect humans.
