Antarctic penguins spend about 75 percent of their lives in the water. A number of survival adaptations allow them to swim through water as cold as -2 degrees celsius.

Penguins in antarctica—like wildlife worldwide—are part of complex ecosystems that must stay in balance for their inhabitants to thrive. As a new study shows, that balance is threatened in the antarctic peninsula, where concentrated fishing and climate change are making life much harder for penguins.

Presumably diverging from other penguins around 40 mya, it seems that the spheniscinae were for quite some time limited to their ancestral area, as the well-researched deposits of the antarctic peninsula and patagonia have not yielded paleogene fossils of the subfamily. Also, the earliest spheniscine lineages are those with the most southern.
