Name: Methane Ice Worms
Location: Gulf of Mexico, 80 miles off the coast of Louisiana
Description: In 1997, vast colonies of strange, rosy-pink worms 1-2 inches in length were found burrowing in mounds of methane-rich ice erupting from the sea floor in the Gulf of Mexico.
What this means for life in the universe:
The discovery of these previously unknown life forms, living in frigid ocean depths far beyond the reach of sunlight, extend our definition of what constitutes a habitable environment. The discovery provides further evidence that life is tough in the extreme.
