Clusters of brown snails living around the Antarctic vents.
Seven-armed Sea Stars
Seven-armed predatory sea stars use the vent area as hunting grounds.
Predators of the Vents
Researchers observed these sea stars eating yeti crabs.
Bunches of Barnacles
A close view of the stalked barnacles carpeting the rock around the vents
Yeti crabs are found around deep-sea vents. Some species have hairy arms, but the ones pictured here inhabit the waters off Antarctica and have hairy chests instead.
Piece of the Deep Sea
A sample of part of a vent chimney brought to the surface by the Isis ROV.
A second vent fragment. Minerals in the ultra-heated water from the vents precipitates out, leaving behind chimney-like vent structures.
Zoarcid fish caught in a trap deployed by the ROV. Samples of abundant animals were taken so that researchers can determine how they fit into the known animal kingdom.
A ghostly pale octopus caught on camera near the vents. The octopuses seemed curious, or at least drawn in by the ROV lights, and often came right up to the submersible.
