Everyone knows of the Galapagos Islands’ biodiversity and scientific value on land, but a recent deep-water expedition has revealed that this biodiversity carries on fathoms below the bellies of the islands’ giant tortoises.

An international expedition from the Schmidt Ocean Institute has revealed the presence of two pristine, cold-water coral reefs growing alongside the walls and bases of several seamounts over 1,000 feet below the surface.

Tropical coral reefs typically grow within 120 feet of the surface, but have sometimes been found at lower depths. These however were cold-water corals, known sometimes by their shorthand of “stony corals,” and were found at depths ranging from 1,200 to 1,375 feet (370 to 420 meters).

The larger of the two reefs spans over 800 meters in length, the equivalent of eight football fields. The second, smaller reef measures 250 meters in length. They exhibit a rich diversity of stony coral species, suggesting that they have likely been forming and supporting marine biodiversity for thousands of years.
