I'm a science illustrator and although I have seen some very strange creatures as many, watching science programming, this is quite odd.
Firstly, with keen observation and absorbing the links from others to Bryozoans or worm masses, I do not see the resemblance either visually or in
observed nature unless there has ben a profound mutation of these organisms.
Observations:
These creatures have a unified nervous system. It's hard to fake these observed twitches and contractions.
The striated tissue that radiates from the main mass look like tissue specialized for anchoring the main mass and possibly locomotion. That they also
contract independently from the main mass means that they are a different tissue and have a different functional roll in the organisms body.
There seems to be a couple types of tissue, and possibly sensory organs. This means it is a fairly complex organism.
The color of the tissue, if we can extrapolate from the very inaccurate video pallet, seems to be reddish or fleshy like higher lifeforms. Bryozoans
have no such coloration's. This means possibly a circulatory system with a blood or oxygenating component. Hemoglobin? We would need to observe in
laboratory conditions.
I am not sure there is a photo sensitivity as I observed no change in light to elicit the reactions. More likely a proximity touch response to the
camera tractor, water perturbation or otherwise.
The "eyes" observed by some folks close scrutiny might not be eyes in the optical sense, but sensory organs of some sort. If two only, this could
lend itself to a stereoscopic ability to sense in whatever olfactory, frequency of sound, heat or pheromones or whatever in 3 dimensional perception.
These could be organs sensitive to infrared or other non-light effects in any case.
It/they do not seem to have a mouth or orifice we can yet observe. There does seem to be a central area to the mass that could open only when a
suitable organism is within proximity. The camera and tractor is cold so might not have enough heat or the right "scent" to elicit a feeding
response.
The viscus coating, as in other organisms from insect to plant or higher forms of life, could be many things. the most logical is a protective layer
like fish have. It could be mucous secreted by specialized pores to resist water and waterborne bacteria and chemical components. It could also double
as protection and might have bio-toxins or could even be a bacteria symbiotic partnering. This could be an altogether other form supplementing a
protective nature that are like the bacteria in our own stomach and intestinal tract. Complimenting the creatures functions for anything from food
absorption from bacteria it my eat, or stinging toxins like jellyfish and certain other creatures. It could even be like spider toxins that dissolve
tissue for absorbing nutrients.
There does seem to be a relationship with the water. You will notice the striated slimy tentacle like structures seem to extend into the water in the
second subject video, and seem to be just hanging into the water being moved by currents. It would need water to supplement its body tissue. It
might also be fishing for small water insects, bacteria or other such food sources.
Until this is observed in this habitat much more thoroughly or in laboratory conditions we can only speculate the nature of this organism.
My first impressions where the pods in Alien movies. When the pod first opens, the slimy bulbous mass inside looks similar. But that is simply a
visual association.
This will be very interesting to find out about if already known but modified by environment not it's own. But maybe it is from "elsewhere".
In any case there will have to be an original organism it is from. These things do not just spontaneously evolve. Such takes millions of years of
evolution.
I'll be watching, and gagging.
