Penguins have a special kind of coloring called counter-shading. This means their backs are dark, and their bellies are white.
When a penguin swims in the ocean, fish look at it from different angles. If a fish looks up, the penguin’s white belly blends in with the light coming from above. This makes the penguin hard to see. If a fish looks down, the penguin’s dark back blends in with the dark water below.
This coloring helps penguins hide from fish and other animals when they swim, so they can catch their food more easily. It is like a natural disguise that helps them survive in the ocean!
