Working on an original creature design for a deep-sea sci-fi horror

Next book I plan on writing is going to be a deep-sea sci-fi horror inspired by films such as Deep Star Six and Leviathan (both released the same year of 1989 funnily enough), with obvious nods to the first Alien film and its knockoffs such as "Creature" and the "Xtro" films (particularly Xtro II) - i.e. big scary monster picking off people one by one in a confined space. Haven't thought of a name for it, I might just call it "the organism" to maintain its mystery and reduce cringe. I'm sure if it ever gets made into a film it'd look different in the finished product, but for its adult stage I imagine essentially a giant, mutant Portuguese man o' war, something like so (not my work):

Domain:Eukaryota
Clade:Amorphea
Only instead of being venomous it emits a frequency/wavelength that accelerates maritime hallucinations and nitrogen narcosis, while essentially being a massive shapeshifting colony organism in its parasitic larval/pupa stage that responds to changes in blood pressure and heart rate (and it can almost 'sense' what you're most afraid of), which begins immediately as soon as its eggs/spores make it inside of you (it shares similarities with slime mold in this stage, and has regenerative abilities like slime mold, also a reference to the EU xenomorph ability of regeneration) at which point they begin to multiply and form an egg sack that grows and multiplies as it converts all surrounding tissue into new egg sack, after a certain point it enters stage 2 of the infection once the host is essentially a giant reproductive organ and eventually results in stage 3, the gestalt or "adult" stage, in which a brand new colony organism is produced that is morphologically similar to a Portuguese man o' war or other siphonophores, only the lore indicates that it is more akin to a "proto-siphonophore", an ancestor relative, not a sibling. I'm still working on the lore but basically it begins with the collision of the oceanworld Theia with Earth 4.5 billion years ago, the origin of water - and thus life itself - on Earth. Essentially all life in our oceans evolved from this organism.

What would/should be some of the other feats of this organism? I've read that similar organisms can even form an exoskeleton, such as corals.

Edit: Also if you think you have a cooler name for it than "the organism" by all means. I jokingly call it the "ooze golem" since it is found in sediment and its shapeshifting abilities in its larval/pupa stage.

Edit 2: Perhaps it would be more accurate to refer to its stage 2 form as a "pupa", as opposed to a larva, as its larval form would be microscopic and look something like this:

How does this pan out with it having a parasitoid reproductive cycle? If the Organism needs macofauna hosts for its young, it can’t predate their existence. Or is it the last surviving Theiaian, with Theia having possessed its own multicellular ecology before its collision with earth, leaving only Theiaian microorganisms and this guy whose microscopic larva were apparently durable enough to survive, only to gestate now once suitable hosts had evolved?

Well the second image is of a Myxozoa which are,
highly derived cnidarians that have undergone dramatic evolution from a free swimming, self-sufficient jellyfish-like creature into their current form of obligate parasites composed of very few cells – sometimes only a single cell [citation needed]. As myxozoans evolved into microscopic parasites, they lost many genes responsible for multicellular development, coordination, cell–cell communication, and even, in some cases, aerobic respiration. The genomes of some myxozoans are now among the smallest genomes of any known animal species.
So it is essentially a archaecnidarian, closesly related, but not quite the same, having traits of both cnidarians and slime mold
Edit: By the way, the largest cnidarians can get up to 8 feet in diameter, weigh up to 470 pounds and have tentacles stretching as long as 130 feet (longer than your average blue whale)

Interested to see how this will develop too.

It will most likely be the latter, but I'm going with "they started out as free-swimming self-sufficient animal-slime mold hybrid that eventually evolved into parasites as more organisms emerged on earth", also due to their trans-temporal nature they exist non-organically in pocket dimensions outside of linear time.
WIP/concept for the cover art using some AI art I found online:

Remember, you can look at the more... interesting marine and animal life out there and composite features you find appealing.
Commonly known examples, thanks to media using them a lot, are the Angler Fish and the Moray Eel.
Although there is a lot of sensationalism in YouTube videos, some of them do contain some legitimate leads you could follow to research the actual creatures found in these videos. ;)
Edit:
Some random examples.
Skeletons made of cartilage? Mix and match that with the idea of a coral's biology to create an idea of something very... interesting.
Sky's the limit, basically.

I want to stay away from the angler fish because its morphology was already used as the creature concept in Leviathan (1989, of course), but the coral I'll definitely end up incorporating into its morphology.
EDIT: I could have a scene toward the beginning of the story where the crew of the Mary Celeste is mining the clay minerals near the Challenger Deep, wherein they get attacked by an angler fish driven insane by the frequencies of the organism nearby :p

Oh yeah, I completely understand why since the Angler has been overused, but I was using it as a well-known example of what weird shit exists in this world you could use for inspiration. ;)

Just explore on YouTube weird animals and marine life, especially those living in deep/sealed caves and the ocean's depths, and you might find some intriguing elements you could use for compositing.
