Researchers in Hawaii have discovered three probable new species of fish while on an expedition in the protected waters of the Papahanaumokuakea Marine National Monument.

In a statement released Wednesday, National Oceanic and Atmospheric Administration officials said divers collected two previously unknown species of and filmed a third.

NOAA's Randall Kosaki, the expedition's chief scientist, said the team collected the first specimens of male Hawaiian pigfish about 300 feet below the surface.

The scientists also observed significant coral mortality in the region that was the result of a mass bleaching event in 2014.

Hawaii Institute of Marine Biology researcher John Burns said a 2015 trip found about 90 percent of the coral around Lisianski Island had died. This year, the team found that dead was covered in a green algae bloom.
