Researchers traveling along the Kuril–Kamchatka and Aleutian trenches in the northwest Pacific Ocean used a manned submersible to find tubeworms and mollusks flourishing at over 31,000 feet deep. The deepest part of the ocean goes down to about 36,000 feet.

Scientists have filmed odd communities of life flourishing deeper in the ocean than ever before. The chemosynthesis-based life-forms get their energy from chemical reactions, powered by gases seeping out of faults on the seafloor.

Known to only live in the Atlantic and Indian Oceans, the Solumbellula appeared in the Pacific for the first time to scientists' surprise.
