Chart
A chart I made because I got bored in my Graphics Communications class.



Key
Black- related. (Confirmed by the PDA) (only expection to this is sea dragon and sea emperor)

Red- possible relation. (fan theroies)

Blue- other. (other reasons)

Unamed Creature- Theroized Creatues stated by the PDA (including very subtle mentions)

Theroized Creatures- Any Theroized Creature not stated by the PDA, and is instead theorized by fans

Families and More
Segemented Exoskeleton/Double Eye Sockets Family - Sand Shark, Boneshark, Rockgrub, Biter, Blighter and Theta

These creatures have evolved from a creature that had a segemented exoskeleton. The biter and blighter have lost the segemented  exoskeleton for faster speed while the rest kept it. The Sand Shark and Rockgrub both have burrowing behavoir so it may be possible that the common ancesctor burrowed as well and the Boneshark and Biter gave up the trait.

Eel Family- Ampeel, River Prowler, Ghost Leviathan

These creatures have evolved from another eel like creature. The River Prowler has no electrical prongs so either it has lost them completely or spillted off eariler. The Ampeel and Ghost Leviathan both have electrical prongs suggesting they are very closely related and that their common ancestor had electrical prongs. Though the Ghost Leviathan has cover up its electrical prongs, making them useless, as it needed to favor superior maneuverability and superior navigation over electrical defense.

One Eyed Creature Family - Peeper, Eyeye, Reginald, Oculus, Red Eyeye and Alpha Peeper

As the name suggests. These creatures only have one eye. The Alpha Peeper is said to be the first creature to have eyes. The Alpha Peeper developed photosensitive skin on each side of its body, due to the abundant amount of light in the shallows. These photosensitive skin later became eyes. Sometime later it evolved into the Peeper, Eyeye and Reginald. Some Peepers eventually evolved to adapt to the Jelly Shrooms. The path that lead to the Eyeye had evolved to have its one eye take up most of its body while the other paths kept the trait of the one eye being on both sides. Later some Eyeyes would adapt to stay alive in the lava zones. Despite having one eye, the Spadefish isn't apart of the family, (or at least not mentioned in game) So the Spadefish most likely just evolved to have one eye by itself without evolving from the Alpha Peeper.

Stalker Family - Stalker, Lava Lizard (possibly)

The Stalker is one of the oldest creatures on the planet. Hitting the sweet spot of both speed and size. It has no bioluminescence and has giant teeth, so it may have some relation to the Lava Lizard which also has giant teeth, no bioluminescence and both are similar in size.

Ray Family-  Jellyray, Rabbit Ray, Ghostray, Crimson Ray and the Alpha Ray

The Ray family is a family of the rays (duh). The Alpha Ray is the first in the family, It was a predator that hunted smaller animals. Over time it evolved and lost its predator status and replaced it with a posionus skin. The Jellyray, Rabbit Ray, Ghostray and Crimson Ray are what is left. The Crimson Ray and Ghostray still have the foward mounted eyes that the Alpha Ray had to hunt. While the Jellyray and Ghostray have transparent skin.

Crabs- Cave Crawler, Blood Crawler and Crabsquid (possibly)

This family has multiple legs and can walk around on the sea floor. While Cave Crawlers often live above land. They can live underwater if they want to. The Blood Crawler and Cave Crawler are closely realted. While the crabsquid may be a more distant relation. The Crabsquid had evolve to have an EMP blast as a way to counter the rise of a fauna that had electrical attacks. The Crabsquid is apart of this due to the Cave Crawler having a gas exchange membrane which could be similar to the Crabsquid's inflated membrane. (as pointed out by Bippity)

Invertrabrate Creatues - Reefback and Arctic Reefback

The Reefback came from other invertrabrate creatures, The evolution to have a shell was used to protect from other predators. Any predator that can break the shell is most likely long gone. Reefbacks have very long lifespans and can live centuries. Reefbacks eat food by relasing enzymes into the water. While the glands that hold the enzyme look similar to Gasopod's glands, they are not closely related. The Reefback and arctic reefback are obviously closely related. the only different is that the Arctic Reefback has a bump on its back while the reefback doesnt. Due to the expansion not being out yet and things can change. An offical placement for the Arctic Reefback can't be said until more information is given on the Arctic Reefback

Forelimbs Family- Sea Dragon and Sea Emperor

The Sea Dragon and Sea Emperor, two giant creatures with many similarities. While one can fire magma and another can cure Kharaa. These two species most likely came from the same ancestor. The Sea Dragon has arms with giant fins perfect for slapping prey, while the Sea Emperor has paddle arms. The Sea Dragon is one of the oldest creatures on the planet and is nearing extinction. The Sea Dragon's forearms are suggested to come from other creatures with forearms over ten million years.

Cuddlefish (Cutefish)

The friendly fish that follows you around and likes magic tricks, tickles and more. Its origin is unknown. Can understand commands like a dolphin.

Warper

A strange teleporting creature with robotic parts. Built by the precursors to kill anything with Kharaa. The origin of the creatue used is unknown, but based on how the creature looks like, it was most like a predator.

Amoeboid

The blue fauna that looks like flora but isn't. It is just a simple, non-sentient organism that is a scavenger.

Anomaly's Remake Progress
Anomaly has been taking their time to make a remake of this chart that looks a lot better.

BippityBop (Helped fix info I got wrong . which happened to much, and gave other possible relations)

AnomalyDetected (Remaking this chart :D) (well I at least think they still are doing it)

All the pictues are from the Subnautica Wikia, so I don't own the images

The concept art of the Arctic Reefback is obviously not mine.
