Weird and Wonderful: Giant tubeworms

Towering colonies of giant tubeworms, Riftia pachyptila, reign over deep-sea hydrothermal vents. They cluster where heat and sulfur spew into the sea, extending their feathery red gills to reach cooler, more oxygenated waters. The worms don’t have a gut and they don’t eat food. Instead, they host bacteria inside their bodies that convert minerals from the vents into energy. As volcanic activity deep below the seafloor shifts, the hot, mineral-rich water stops flowing. Eventually, the entire colony dies off. But when new hydrothermal vents pop up, even hundreds of miles away, giant tubeworm larvae quickly settle and colonize them.
