methane ice worm

Sirsoe methanicola

Classification

Sirsoe methanicola is a species of polychaete worm that inhabits methane clathrate deposits in the ocean floor. The worms colonize the methane ice and appear to survive by gleaning bacteria, which in turn metabolize the clathrate. In 1997, Charles Fisher, professor of biology at Pennsylvania State University, discovered the worm living on mounds of methane ice at a depth of half a mile (~800 m) on the ocean floor in the Gulf of Mexico.
