Expedition 15 Videos

Tubeworms are some of the most extraordinary creatures at hydrothermal vents. With no stomach or gut, they survive by partnering with bacteria that live inside their bodies and make the nutrients the tubeworms need to survive. In order to study those bacteria, scientists have to get their hands dirty. In this video, watch marine biologist Horst Felbeck dissect a tubeworm to remove its trophosome, the organ that houses its symbiotic bacteria. (Warning: This clip gets a little gory).
