Kinda amazing how they can get these shots. Animal intelligence continues to exceed our expectations.

Since it's exhaled air, hasn't the oxygen been used already and it's higher in CO2.

I had the same question but obviously it seems to work... maybe the mom knows and does not use up all the O2? Or maybe even with higher CO2, it's still better than no air at all?

Nature is amazing.

The fact that it obviously works means the all oxygen hasn't been used.

The efficiency of lungs would determine how much oxygen is used from a given 'breath' of air.

Since nature has provided this method of 'buddy breathing' it stands to reason there is a reason why it works.

We certainly exhale O₂ as well as CO₂.

An athlete's lungs are more efficient than those of someone who's sedentary.

A baby seal would seemingly need less than a larger seal.

The fact that an adult seal can stay submerged for half an hour is probably a clue.
