10. At the bottom of the seas where hydrothermal vents pour their chemicals into the ocean, there is no light and little oxygen, yet giant (2meters long) tube worms live there happily. These remarkable creatures have no mouth and no anus, living instead off the excretory products and dead cells of their symbiotic lithotrophic bacteria. These tube worms are bright red because they contain large amounts of hemoglobin, which is critical to the survival of their symbiotic bacteria, and hence the worms. This specialized hemoglobin carries O2 and H₂S. In addition to providing O₂ for its own oxidative metabolism, what role might this specialized hemoglobin play in the symbiotic relationship that is crucial to life in this hostile environment
