Penguins may help prosecute oil companies

Penguins from the southern tip of Argentina sometimes get lost as they search for food and they often end up on warmer beaches in Brazil.

But now, researchers have discovered they often bring important scientific data with them like oil samples that could help environmental protection officers locate those responsible for oil spills.

That information is critical as numerous companies tap into some of the largest recently discovered deepwater reserves.
