A scuba diver swims among colorful fish and coral in the northern Great Barrier Reef's Ribbon Reef. Researchers exploring the deep edges of the reef recently found coral living at 410 feet (125 meters).

Coral was found lower than ever seen before in the Great Barrier Reef. The corals are four times deeper than most scuba divers can dive.

The corals are found in a place that is difficult to explore because of bad weather.

At 410 feet (125 m), these corals are the lowest ever seen at the Great Barrier Reef, though many non-light-dependent corals can survive at thousands of feet below the ocean surface.
