Vent Crab
Photograph by Emory Kristof

A brachyuran crab with hard-won snack poses for a close-up portrait on a private bump of volcanic rock. Constantly improving imaging technologies have played an important role in deep-sea vent science. Still photographs and video footage help scientists record information about behavior and ecological interactions that would be difficult to capture in any other way.
