Even the very smallest penguin, the fairy penguin, weighs 1kg, which is about as much
as a herring gull.
Butherring gulls have a 1.4m wingspan, compared with just 32cm for
the fairy penguin. Water is 784 times denser than air, and, around 62 million years ago, penguins began evolving adaptations for
swimming underwater.
Their bones are filled with heavy bone marrow rather than air and they have much larger stomachs
for undergoing long fishing trips away from the nest.
