A team of researchers from the California Academy of Sciences retrieved 13 reef monitoring devices that had been placed in deep coral reefs in Guam nearly a decade ago.

They found 20 potential new species, including crabs and sponges.

Louise Rocha, a marine biologist and diver on the team, says there could be more new species.

Researchers have also started a two-year expedition to retrieve 76 more deep reef monitoring devices across the Pacific Ocean.
