These snails lay eggs in a spiral tower and the adult snail sits on top of the tower waiting for the eggs to hatch. The snails were all clustered together along a cable route SUM1W2 at Southern Hydrate Ridge. We did not see the snails at any location other than here. The depth at this location was 776 m.
