How Giant Tube Worms Survive at Hydrothermal Vents

Season: 1
Eps: 3

In this episode, Ed talks to Colleen Cavanaugh and finds out how the tubeworm can live in complete darkness and, more curiously, without even having a mouth or anus. In a process called chemosynthesis, symbiotic bacteria inside the tubeworm use hydrogen sulfide spewed from the vents as an energy source for themselves and for the worms.
