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

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.
