Researchers at the Monterey Bay Aquarium Research Institute (MBARI) recently captured rare footage of one of the rarest things in the ocean.
The Giant Phantom Jelly was seen in the deep waters of Monterey Bay in California.
This enormous jellyfish was first documented in 1899 and has only been filmed nine times throughout thousands of dives in Monterey Bay. Globally its only been seen 100 times, which is why scientists still know very little about this sea creature.
They live anywhere from surface level to 21,900 feet but prefer the midnight zone, which is too deep for light to reach.
The bell of this jellyfish is over three feet across, and the arms can be up to 33 feet.
Scientists say that Giant Phantom Jelly appears in all oceans except the Arctic. The one captured in this video was filmed by an ROV at 3,200 feet down.
