The giant shearwater flocks hunt the krill swarms
sometimes diving to depths of forty meters to reach them.
A large humpback eats three tons of krill a day.
The polar seas in summer are the most productive on the planet
and the whales gorge themselves round the clock.
The fat reserves they lay down now will keep them alive during the year to come
but it may not always be this way.
Fish and krill stocks are declining so rapidly that spectacles like this may soon be part of history.
Once the mother and calf have reached their feeding grounds, they will separate.
With luck, the calf will make the epic journey across the oceans from equator to pole another seventy times
cruising back and forth between the shallow seas where life proliferates so abundantly on our planet.
