The absolute highlight for just about everyone, today, was the discovery of a tube worm at the Von Damm hydrothermal field. While tube worms are some of the most iconic animals to have been discovered at vent fields in the Pacific they have only been found associated with cold seeps, previously, anywhere in the Atlantic Ocean. So while first impressions were that this tube worm looked more like its nearest Atlantic cold-seep cousins it was, nevertheless, the first tube-worm we know of that has ever been found at an Atlantic vent-site. We hope to be following up on this in more detail in tomorrow's dive.
