Tube worms near hydrothermal vents at EPR (2004)
Tue, 08/25/2009 - 11:14 — mgds
Close-up view of tubeworms (Riftia pachyptila), bathed in dilute hydrothermal fluids, at water depths over a mile and half (~2.5 km) under the Pacific Ocean, can tolerate high temperatures and sulfide concentrations. They have tubes that can reach lengths of 3 m, and the red "plume" that sticks out of the top contains hemoglobin, which is used to exchange compounds with the environment (e.g., hydrogen sulfide, carbon dioxide, oxygen, etc.) that are used by symbiotic bacteria that live in a specialized organ (trophosome) to make energy.

Time-lapse animation sequence of hydrothermal vent system evolution (2004)
This animation shows the evolution of hydrothermal vent systems that occur at underwater volcanoes. Warm mineral-rich water released from the seafloor creates suitable habitat for organisms including tubesorms (Riftia pachyptila) and clams. Over time, the distribution of these organisms within their habitat can change, as individuals die and are replaced by others. Major disturbance to the ecosystem occurs during voclanic eruptions then the area is inundated with hot molten lava.

Alvinella Worms at EPR (2003)
This video shows a community of tubeworms known, as Alvinella. The shimmering water that surrounds the community is the result of warm water (hydrothermal fluid) released from the seafloor that creates a microhabitat in which these organisms flourish.
