The other week, after the Cascade Creature video was going viral on a large scale, and I made a post about it.
Which you can read here.
The original article I cited from the Daily Mail here, pretty much hit the nail on the head, with the questioning whether this ‘mysterious’ creature could be nothing more than a member of the Ulmaridae family. Specifically, this 'Cascade Creature’ is a confirmed Deepstaria enigmatica, as one of you thankfully informed me of last night. You can read more about the rare sighting, and much more rare filming of this deep sea creature here. It was filmed about 5000 feet below the ocean’s surface by an unmanned sub.
For those of you unfamiliar with this larger than life jellyfish, here’s a bit of a summary:
“..most specimens reported colorless but deep brown exumbrella and stomach lining a paler brown recorded once. ”. “Gastrovascular canals fine, somewhat irregular-edged, forming reticulate network across most of bell,” [x]
This 'reticulate network across most of the bell’ is the questionable hexagonal patterns seen on the skin, as seen in the image below.
“Our observations of both species of Deepstaria suggest that they usually hang motionless with the umbrella open…It seems probable to us that medusae in this genus are large ambush predators in the meso- and bathypelagic environment…we speculate that the feeding behaviour might be as follows. The medusae usually hang vertically and motionless with the bell open; occasional peristaltic contractions probably enable them to swim slowly, at least enough to retard sinking. Because the area of the subumbrella is so large, upward-swimming prey occasionally would swim into it. Once prey enter the large subumbrellar chamber, the contact stimulates rapid contraction of the coronal muscle, pursing the umbrella shut and trapping the prey. As the prey attempts to escape, it contacts nematocysts on the subumbrella, being repeatedly stung until weakened. It may additionally become covered with mucus and further immobilized. Then peristalsis and ciliary movement could transport the prey towards the mouth where the oral arms could grasp and engulf it…’Bagging’ prey in this way is not known in other medusae.” [x]
