This suggests that the tube worms are the second-longest-living non-colonial species ever found in the depths of the ocean – the deep-sea clam Arctica islandica can live for 500 years or more.

They found that two species of tube worms actually trap methane, a powerful greenhouse gas, through a never-before-seen symbiotic relationship between the worms and methane-eating bacteria.

An expedition to explore the bottom of the sea has glimpsed tube worms living near hydrothermal vents, the first time the bizarre creatures have been seen in the Atlantic Ocean.
