This deep-sea crab was caught on camera trying to eat bubbles seeping from the deep seafloor! While exploring the seafloor off the coast of Vancouver Island, British Columbia, MBARI's ROV came across this surprising behavior. These bubbles are gaseous methane seeping from the seafloor. Methane hydrate, a solid ice of methane, formed when the crab attempted to eat the bubbles. This illustrates the unusual property of hydrocarbon gas under the extreme pressure and cold temperatures found at 1,260 meters below the oceans surface. The crab quickly found that it had made a mistake as its mouth parts became frozen together, forming a "milk mustache" of solid hydrate. It then tried to remove the material, seen as small flakes hydrate floating away.
