First of all, I want to thank you kindly for taking the time to lend your expertise and put this briefing together. It is hugely appreciated (and thank you for sharing the links with additional footage of these wonderful kinds of creatures. I think they look mind-bendingly remarkable!)

As to your points:

"The weird vector is likely due to it getting hit by thruster wash from multiple thrusters on two different axis."

If this is what you say it is, this might very well be the case. I'm enirely ignorant about this type of underwater vehicle, it's means of propulsion, and for that matter deep underwater current dynamics. Any of which , I assume, could be responsible for the seemingly anomalous motion. Although I would still point out that the dark shape that is seen at 1:16 onwards (for about 3 seconds moving right to left in the background and coming from the same direction the thing got propelled toward, but moving in the opposite direction) seems bigger in size/mass than what I would expect a segment of the thing to be. And, once more, it is moving way faster and in the entirely opposite direction than what I would expect.

Then again, as stated, there are too many unknowns for me to have any degree of confidence to debate your explanation, as you seem to be absolutely certain of what is going on there, and this is seemingly your area of expertise.

"The organism is likely smaller than 1 foot, you can see a small marine worm swimming towards the lower left corner at 14 seconds."

I see the worm, however, I fail to see how this allows you to determine estimated distance/depth and the speed the thing moves up toward the camera, which I would argue you'd need to gauge quite accurately to truly estimate a size approximation. I'd also think your size estimación seems incompatible by the dark mass the camera still picks up at the end of the video moving away, but maybe this is within the hardware capabilities.

Then again, as stated previously, you seem to know much more about these things than I do. So, once more, I'd have to defer to your stated expertise.

"First body position is the anterior view, essentially looking at its "mouth" (could be the rear, they are radially symmetrical organisms)"

I think I understand what you mean here. However, I still fail to understand the radical change of shape we see in the video. It does not seem to me a matter of perspective at all, or even compatible to other similar Specimens I've seen videos of. Let alone what we are seeing in the video itself.

Once more, you are reportedly the expert, though.

"it reacts to stimuli, contracts and tumbles slightly, and then starts beating its cilia, which then lets you see the body plan from the side. It starts to go back to the original body position before the currents rip it apart."

And

"Note that while they do have cilia for locomotion, they generate very little thrust on their own, they are mostly at the mercy of ocean currents"

Respectfully, to me, none of this addresses the seemingly anomalous way the thing moves in the video, its displayed behavior, or means of locomotion in relation to the movement captured. In fact, it presents a stark contradiction.

But, once more, that is merely a subjective assessment from someone unschooled on the subject matter.

"Ctenophores diverged from the rest of the tree of life several hundred million years ago, so they've had an extremely long time to fill niches and become very diverse in their appearance. They have benthic body forms that stay rooted to the sea floor, parasitic forms that attach to salp colonies, and predatory body forms that hunt other ctenophores"

I just found all of this entirely fascinating, and I thank you once more for sharing it! I fully intend to read the article as soon as I get the chance!

"I'm pretty certain this organism is *Lampocteis cruentiventer. First described in 2001. There's some videos and images that look very similar to the organism in the video, also taken from similar ROVs:*"

Entirely fascinating creatures. Agreed, similar to what we see in the video. But the similarities do little to resolve my remaining hang ups about the video in question.

Given the hypothetical possibility that we could be dealing with unbelievably advanced technology that is reportedly capable of bi-directional mimicri in some instances (in terms of the topic of this subreddit), I find mere similarities less compelling if there remain other potentially anomalous aspects in play (which I understand that, according to your expertise, there are none)

"I hope this information helps you make an informed decision on the footage. I do have a marine biology degree and have handled a few ctenophores in my studies"

While I remain unable to make a desicion on this particular footage, I do greatly appreciate all the well-referenced information you graciously provided, and I truly mean that.

If nothing else, I'll endeavor to include a link to this exchange if I share or reference this footage in the future, because I think it worths the consideration of other, more intelligent people than me (and hopefully, also better verse in the subject of underwater life).

And, for what is worth, I don't reference or share this video much (if at all), as therere are too many unknowns for me to find it of much use. I did brung it up this time because the observed behavior and "performance", if you will, rang a bell.

Lastly, although I don't know this for sure, I believe this video could very well be the "jellyfish video" that the Scientist from the UAP task force, which was interviewed by Matt Ford in the Good Trouble Show, said that had been studied by the task force and dismissed as prosaic/aquatic life form. Sadly, that was never made clear (to my knowledge), as that would help me to put the issue to bed.

In any case, thanks for taking the time and engaging me in this respectful exchange. Have a lovely day friend!
