I'm referring to this Daily Mail article, but there are more available. Scientists recently described the discovery of the Venus Hair bacteria, which was found on the ocean floor near the site of an underwater eruption adjacent to El Hierro island, one of the Canary Islands.
According to the DM:
"The vast lawns of bacteria, which was named Thiolava veneris, were several kilometres in diameter.
The researchers studied the new bacteria and found that it can thrive in the sulfur-rich environment left by a volcanic eruption.
Here's a somewhat more scholarly, though short, discussion. There's a link to the abstract of the paper in it. To read the actual paper, you'll have to pay good money, unfortunately.
