An alien-like jellyfish has been discovered on the Enigma Seamount near the Mariana Trench, 2.3 miles below the surface of the sea.

The creature was spotted by the NOAA Office of Ocean Exploration and Research during one of their dive on April 24.

It was noted for having two sets of tentacles - one short and one long.

The Mariana Trench is located deep in the Pacific Ocean between the Philippines and southern Japan.
