The first time the film was recorded

This is the first full picture of "alien ghosts". Previously, humans could only see it through an incomplete specimen collected in 1966.

The team of Professor David Gruber (City University of New York) and colleagues at the Radcliffe Institute of Advanced Studies (Harvard University) accidentally turned up images of a strange creature offshore. San Benedito island in the Pacific Ocean belongs to Mexico.

"This is a crazy, bizarre thing like an alien creature," said Professor Gruber. Because his team, including top biologists, doesn't know what they record.

The video, filmed by the remote control device named Hercules, is 899m deep, depicting a 68cm long, 56cm diameter, clear and virtual body. Scientists have studied a lot of documents and finally determined it to be the mysterious jellyfish called Deepstaria enigmatica.

The strange jellyfish approached Hercules camera and found a way to eat the machine - (Cut from the research team's clip).

A ghost lost and became a party for crabs - (cut from the research team's clip).

Deepstaria enigmatica was first discovered in 1966. So far, there have been many studies but no one has actually seen it again. All information about this jellyfish named "alien ghost" is derived from the only specimen that is located in the British Museum of Natural History.

However, the specimen in the museum is only part of the jellyfish. It was the expedition team in 1966 that caught it but unfortunately it was too big for the device to collect samples they brought and only part of the jellyfish was put on display with the human world.

Hercules was very lucky because the machine captured the close-up of the jellyfish that was catching its prey. Perhaps it was mistaken for Hercules to be a good prey, so he tried to swallow the machine before releasing it because it was too difficult.

At the shooting, a group of crabs are surrounding the jellyfish and seem to be trying to catch it for a party.

Hercules is a dedicated ocean videographer, able to capture images in low light and swim in the water like a marine creature to ensure that it does not disturb the ocean life when recording.

The study has just been published in the American Museum Novitates scientific journal.
