How do giant red-tipped tube worms at hydrothermal vents get from place to place in the deep sea? And how do their larvae (captured here by #ROVJason) survive the trip in the cold, dark ocean? At active vents, hot water mixes with seawater to form plumes that rise until they cool off, about 200 meters (roughly 650 feet) above the sea floor. This fast-moving water forms a sort of “larval superhighway” that helps vent animals colonize new areas. Learn more about how vent animals survive–and thrive
