Vampires aren't scientifically recognised organisms on Earth, we don't call Dracula sci-fi (and I'm clearly referring to the humanoid vampires of legend, not bats or vampiric animals).
The same goes with werewolves, or any number of folk monsters.
In fact vampires are a perfect analogy. You can tell a vampire story from a science fiction perspective, but a vampire does not necessarily make something science fiction.
Again, it's a question of classification, whether vampires are science fiction or fantasy. The matter can be tested by fitting vampires into science fiction categories: is vampirism a virus?..are vampires aliens/extraterrestrials? ..are vampires from the future? ..is vampirism a technology? If you answer "yes" to any of the questions, it's about sci-fi.
In the same way, you can fit vampires into the categories of fantasy: is vampirism mythology?..are vampires associated with magical powers? ..are vampires supernatural? If you answer "yes" to any of the questions, it's a fantasy.
The matter can also be tested in the light of known science: can vampires exist in some scientific context (pseudo-scientific, like traveling at the speed of light) that can be understood as possible? ..if the answer is yes, it's about sci-fi.
Fantasy and sci-fi genres are overlapping in many cases, so in most cases you can't completely line the binary of being only fantasy or sci-fi. For example, the "Frankenstein", which is the progenitor and prototype of many monsters in films and literature, is classified as science fiction, but there are creatures that do not have a direct attachment to any genre category or fit both, they are just fiction like Godzilla...although Godzilla is also some times associated only with science fiction.
When it comes to the monster of the movie Alien in all its forms, it goes directly into the category of science fiction aliens/extraterrestrials. Xenomorph, facehugger, chestburster, etc. are science fiction in themselves.
In the end, whether or not a sea version of Alien has sci-fi "monster-wise" depends on what the creature represents. As I said before, the movie Abyss shows a creature found in the sea (without any major horror elements) and it is classified as sci-fi (not fantasy) with the appearance of the creature in the movie.
Alien 3 is a good example of this. If we forget about 10 minutes from the beginning of the film, and also EEV and Bishop's reconnection scenes, and determine that the prison is located on Earth, the sci-fi definition of the film depends roughly only on the alien monster.
