The deeper into the ocean you go, the weirder life seems to get. It may look like a spaceship out of a sci-fi film, but the creature in this video from the National Oceanic and Atmospheric Administration (NOAA) is actually a jellyfish.

On April 24, the alien-like hydromedusa was spotted at a depth of around 3,700 meters (12,100 feet) in an area of the Mariana Trench called the Enigma Seamount in the Pacific Ocean.

In a statement , NOAA said: “You'll see that the long tentacles are even and extended outward and the bell is motionless. This suggests an ambush predation mode. Within the bell, the radial canals in red are connecting points for what looks like the gonads in bright yellow.”
