“Cosmic” Jellyfish Is it a UFO or a Jellyfish?

“Cosmic” Jellyfish
Is it a UFO or a Jellyfish?
Scientists Discover Unique Sea Creature
This stunningly beautiful jellyfish was seen during Dive 4 on April 24, 2016, while exploring the informally named “Enigma
Seamount” at a depth of ~3,700 meters.

Scientists identified this hydromedusa as belonging to the genus Crossota. 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.

It’s a UFO ― an underwater fishy object.
A jellyfish that looks amazingly like a flying saucer was recently filmed by a team of marine biologists from the U.S. National Oceanic and Atmospheric Administration.

This “UFO” isn’t really unidentified. Its scientific name is rhopalonematid trachymedusa, a type of deep-sea jellyfish. It was filmed last week by scientists aboard the Okeanos Explorer, a NOAA ocean research ship now exploring the National Marine Sanctuary of American Samoa.

Watching the jellyfish move around the deep ocean can be a hypnotic experience.

The researchers who filmed the bizarre creature said the jellyfish has two sets of tentacles, one set facing upward and the other downward. The reason for this is unknown.

It's one of the most hostile places on Earth and extends seven miles (11km) below the waves at its deepest point, but the Mariana Trench is full of secrets. A deepwater exploration mission of the area has spotted beautiful, unknown jellyfish with two types of tentacles as well as a number of other bizarre animals just one week into the study. The orb-like jellyfish was spotted on a dive at a location named Engima Seamount at a depth of 12,139ft (3,700 metres). While experts were able to identify it as belonging to the genus Crossota, they are unable to assign a precise name to the pretty hydromedusa.

They filmed the jellyfish 'floating' through the depths with its long tentacles extended outwards and its bell motionless, suggesting 'an ambush predation mode'. It is thought the red colour in the bell is the creature's radial canals, while the bright yellow may be its gonads. The researchers believe this animal is an ambush predator which waits motionless for something to bumble into its tentacles. The jellyfish was filmed by experts aboard the National Oceanic and Atmospheric Administration's (NOAA) ship, Okeanos Explorer on April 24 using the remotely operated vehicle (ROV) Deep Discoverer. Scientists nicknamed it 'Microsoft Paint', which looks like a resemblance to a jellyfish drawn in that program design.

They are in the process of collecting information about the poorly known deepwater areas in and around the Marianas Trench Marine National Monument (MTMNM) which protects approximately 95,216 square miles of submerged lands and waters.

It is close to the famous Mariana Trench, which measures 1,580 miles (2,550 km) long, with an average width of just 43 miles (69 km). The distance between the surface of the ocean and the trench's deepest point, the Challenger Deep is nearly seven miles (11 km). In the coming months, the researchers will explore deep habitats, new hydrothermal vent sites, mud volcanoes, deep-sea coral and sponge communities, and seamounts, as well as subduction zone and trench areas. It's hoped the information they collect until July will help improve our understanding of of the deep-ocean habitats of the Mariana archipelago.
