During a mission in November 2021, the Doc Ricketts submarine of the Monterey Bay Aquarium Research Institute (GOOD) managed to film a giant jellyfish ghost (Stygiomedusa gigantea) at great depths in the Gulf of California. The jellyfish has a bell more than one meter wide and ribs like ribs that can extend over ten meters. In more than a century, only a hundred of these jellyfish have been observed, especially because of the inaccessible depth at which they live.
