Gentoo Penguins and Fur Seal at Yankee Harbor on Greenwich Island in Antarctica

Photo (c) Linda Garrison
This photo shows the size of the penguins when compared with the fur seal and also how white their bellies are. Since penguins spend so much time in the water, their coloring is much like many fish--white bellies and black backs.

When swimming, the white belly protects them from predators who are lurking below and looking up at the sky (and the white penguin bellies). The white belly also makes them less visible to their prey such as krill and small fish.

The dark back of the penguin serves the same purpose. Predators looking down will not be able to distinguish the penguin from the bottom of the ocean.
