A team studying deep-sea vents found that new vents, once they became active, were colonised by organisms similar to those living at established vents nearby. Within a year of a vent starting to release fluid, tube worms, crabs and the bacteria they rely on had all appeared around it and begun to form a community much like the others in the field.
The same researchers, however, did not establish how the organisms travelled between vent sites, which can lie many kilometres apart across open sea floor. They suggested that larvae might drift on deep ocean currents, but stressed that this was only a hypothesis and that they had gathered no direct evidence of the route any organism actually took. Identifying the mechanism, they wrote, would require a very different kind of study.
