Researchers pinpoint how tubeworm babies are dispersed to colonize new vent sites
...thermal vents are very ephemeral. These underwater volcanoes
appear as the ocean floor spreads, and then they rapidly disappear, says Marsh. Scientists have often wondered how tubeworms, which are sessile creatures and cant move about the seafloor, wind up at new vent sites. The key to solving the mystery i...
