Marine biologists with a National Oceanic and Atmospheric Administration expedition in the Mariana Trench encountered a luminous red-and-yellow jellyfish in April, Scientific American reports.
It is believed to be the first time a human has ever seen this species. The scientists will continue searching the extreme ocean depths through June 10.
You can watch the expedition live, too. There are 4 cameras live at the time of this blog post.
From the NOAA video description:
This stunningly beautiful jellyfish was seen during Dive 4 of the 2016 Deepwater Exploration of the Marianas expedition 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.

The deadly 2013 El Reno tornado was 2.5 miles (4 km) wide and killed a team of tornado experts. But as Anton Seimon explains, his colleagues turned that tragedy into an opportunity to confirm a key element of tornado formation.
Some snakes have evolved the ability to glide through the air. For example, paradise tree snakes in southeastern Asia can launch off from a branch and fly as far as 10 meters. Scientists have known that the snakes flatten their bodies to gain lift but new research reveals that they also undulate their bodies as […]
We humans are castaways on an ocean of uncertainty. Since the beginnings of history, our ancestors sought knowledge and understanding about their lives, their relationship with the cosmos, and perhaps take a peek into their future. In such effort—long before the answers of science—earthlings developed a rich variety of divination practices and systems. Many forms […]
For all their amazing growth over the past 25 years, the most impressive thing about the monumental rise of Amazon might be the speed and sophistication of their lightning-fast delivery network. Sometimes it doesn’t even take 24 hours for the idea you ordered to be perched right on your front porch, ready for use. The […]
You could actually watch a Tyrannosaurus Rex walk down your street right now. And no, this isn’t the latest Jurassic Park sequel. Of course, it isn’t real either, just a Google recreation of some pretty realistic looking dinosaurs transplanted right into any environment around you courtesy of augmented reality. Yet it’s just another example of […]
A guy on the Apple discussion forum started a thread titled, “Why do your Charger Cables have the lifespan of a housefly?” That question is probably enough to elicit a whole bunch of head nods from virtually everyone reading this, whether you’re an iPhone user, an Android owner or have virtually any device that needs […]
