Marvelous Medusa
Since April, the US National Oceanic and Atmospheric Administration (NOAA) ship Okeanos Explorer is mapping out the Mariana Trench, gathering geographical data as well as exploring marine life forms. In this video, watch a rarely seen jellyfish, which was seen during the forth dive of the season in late April at a deplth of around 3,700 meters.
Scientists identified this hydromedusa as belonging to the genus Crossota.
