That sounds like an awesome idea.

Indeed it does. I just don’t know when I shall commission for a ref sheet. Will be in the future.

What kind of creatures are part of this water world?

Looking forward to seeing what you come up with.

And I'm pleased my worldbuilding has triggered your inspiration.

Indeed. After I have realized the discoveries we can make beneath the surface. We may even find out if life is out there by going deep down to the bottom and finding out old bits of the past. Perhaps ancient aliens may be dwelling there with advanced technology and their spacecraft. Just a thought.

I think you may have watched The Abyss a few too many times.
Great movie, but a bit on the fantastical side... and it doesn't actually show any real deep-sea life.

However, deep-sea critters do tend to look very alien, from our perspective. Giant isopods, giant amphipods, crabs of all sizes, squat lobsters, prawns, blind shrimp, sea spiders, urchins, starfish, hagfish, tube worms, bristle worms, boneworms, sea cucumbers, 7-arm octopus, clubhook squid, giant squid, colossal squid, deep-sea jellyfish, gulper eels, anglerfish, hatchetfish, globfish, deep-sea corals... it's a weird world down where the sun never shines. Modern science thinks it has only catalogued less than a tenth of all the species that might be down there, though we probably have already discovered members from every major genera.

The deep sea abyssal plains are mostly devoid of organisms larger than bacteria and a few tiny invertebrates. Hotspots of life are clustered around hydrothermal vents along the mid-ocean ridges, and the slopes of seamounts, where nutrients are concentrated. The vast majority of the water column and open oceans are populated only by planktons near the surface, zooplankton below them, and then only the marine snow (small dead things and their poop). Most of the deep-seabed is diatomaceous ooze.

If you get really lucky though, you may encounter some whale bones, or sunken flotsam, or even a shipwreck.

Sadly, you'll also find quite a lot of plastic litter: not counting underground aquifers and under-ice oddballs like Lake Vostok, there isn't a single body of water on the planet that hasn't been contaminated with microplastics... and larger pieces are so common on the seabed that they're found on every single dive... even in the deepest trenches, under the arctic ice, and in the most remote corners of the ocean.

That is quite understandable. Most certainly those are what we will usually encounter down under.

If you're fascinated by deep-sea creatures, and not terrified of the deep ocean or the unknown (it's a very common phobia, apparently)... then I would definitely recommend trying out the computer game Narcosis on Steam. It happens to be on sale right now, for 50% off until next Monday.

It's a puzzle/exploration psychological-thriller survival-horror game, where you play the role of a deep-sea diver wearing a damaged atmospheric pressure suit that's constantly leaking oxygen, trying to find other survivors and reach the surface alive, after an industrial accident devastates a hydromethane mining facility. While you progress through the game, your character is slowly having a metal breakdown, and starts hallucinating and seeing ghosts... or are they hallucinations?

The game showcases a lot of the exotic kinds of deep-sea life... though it also greatly exaggerates some species to turn them into a mortal danger you have to avoid, since you have no weapons other than a knife. The game's cuttlefish can quickly kill you... anglerfish can bite through your helmet... there is an enormous anglerfish at one point that can eat you whole... and giant spider crabs can impale your metal suit if you get too close, causing a one-hit instant kill. In real-life, anglerfish don't get that big or swim that fast, the giant crabs do actually get that big but this species only lives around Japan and Taiwan (and they are quite harmless), and cuttlefish don't live that deep & would be absolutely no threat to a metal pressure suit.

Also, speaking of the people whom may explore it within the Creatorverse, they may too look alien if I am correct?

What do you mean?

Like how will the cytrans be designed not only by appearance but by function underwater in the deep?

They'll likely have a recognizable design, since they're using modular internal components. The only truly custom part is the external skin... which, when you think about it, is where 99.999% of furry customization happens anyway.

I've decided to adapt the "shark" design as a variation of the common "dragonoid". Same skeletal structure, same organs, same muscles, and just some different features in the head, skin, and tail. Most of the time, though, people just go swimming as they are... or use some sort of machinery or specialized robots.

I’ll most likely do the same for such a setting since it will likely be more appropriate for this.
