I thought this article was cool, because we just learned about hydrothermal vents, and I was always wondering what happened to them when the vent ran out. So I thought this was really cool.
Earthquakes rocked a 15-kilometer long portion of the East Pacific Rise, a deep submarine ridge south-southwest of Acapulco, Mexico. When scientist went down to the area after the earthquakes, cameras saw that an undersea volcanic eruption had killed all of the life living in hydrothermal vent system. Scientists wanted to see how fast the vent system would be repopulated. When they when down, they tested the water and it contained the larvae of Ctenopelta porifera, a rock-clinging gastropod called a limpet. Later these larvae colonized, matured, and started reproducing. This was cool because the nearest system known to host this species was 300 kilometers away. Scientist suggest that the species drop into a state of suspended animation. They can stay in this state for up to 30 days before their nutritional reserves run out. Traveling at a speed of about 10 centimeters per second using undersea flank currents the larva could travel about 300 kilometers in a month
