"There's often an edge to the human eye on the seafloor." Scientists shocked as deep-sea expedition captures 'enigmatic' discovery at bottom of Pacific Ocean: 'Might otherwise be missed entirely' first appeared on The Cool Down.

Scientists have long studied organisms that thrive around hydrothermal vents. But those native to areas known as cold seeps — where gases like methane and hydrogen sulfite leach from the seafloor at near-freezing temperatures — have been little studied.

A team of researchers discovered a “flourishing” ecosystem of clams, tube worms and other creatures over 30,000 feet below the Pacific Ocean. The discoveries mark the “deepest and the most extensive chemosynthesis-based communities known to exist,
