FORT WORTH, Texas, Aug. 19 (UPI) -- A Texas man who works as a surveyor for petroleum companies shared video of a rarely seen deep-sea jellyfish swimming in the Gulf of Mexico.
Phillip Trudeau shared a video on YouTube of a Stygiomedusa gigantea, a deep-sea jellyfish that has only been seen by humans about 115 times since its first reported sighting about 115 years ago.
Trudeau's video, recorded by a remotely operated vehicle, shows the creature swimming 3,330 feet below the surface of the Gulf of Mexico.
The Stygiomedusa gigantea's head, a disc-shaped bell, can grow to more than 3 feet wide and its four arms can reach lengths of up to 20 feet. It is believed to be one of the largest predators among deep sea invertebrates.
