The National Oceanic and Atmospheric Administration (NOAA) has captured this stunning footage of a hydromedusa.

The video was taken earlier this month by a 6000-metre-rated remotely operated vehicle (ROV) on the NOAA ship Okeanos Explorer, America's only U.S. government ship dedicated to the sole purpose of exploring the world’s oceans.

NOAA says: "One of the highlights of our dive on September 6, 2014, in Washington Canyon was when the Deep Discoverer imaged this beautiful hydromedusa. Hydromedusa have red-tinted stomachs to camouflage any bioluminescence exhibited by their prey."
