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.

A second vent fragment. Minerals in the ultra-heated water from the vents precipitates out, leaving behind chimney-like vent structures.

Going Fishing

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.

Ghost Octopus

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.
