At first sight this weird and beautiful jellyfish just doesn't look real. But the footage of this hydromedusa was shot last month by a team from NOAA's Deepwater Exploration of the Marianas expedition.

Scientists identified it as belonging to the genus Crossota.

NOAA says: "Note the two sets of tentacles — short and long. At the beginning of the video, 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."
