Unusual snails found thriving at hydrothermal vents
Dec 10, 2014 – MBARI Senior Research Technician Shannon Johnson Williams described five new species of Alviniconcha snails using DNA sequences. These snails live in the hottest and most acidic waters near hydrothermal vents. Because they live in these extreme conditions, Alviniconcha snails have severely degraded shells covered in spikes or they have no shells at all.
