Describe what is known about the lifespan of hydrothermal vent communities and how organisms may have adapted to these factors
What will be an ideal response?
The individual vents do not last but 10 to 20 years. In contrast to the surrounding deep sea, stability is lacking with the vents requiring that the organism have the ability to colonize new vents as they form. The species mature rapidly and produce large amounts of mobile larvae that can be dispersed by deepwater currents. It is possible that they use whale carcasses as an intermediate habitat where they can grow, and in some cases asexually reproduce.
