Leviathan is a classification given to extremely large creatures of the Subnautica universe. Although the wording of the Reaper Leviathan's databank entry would seem to imply that the leviathan classification is exclusive to predatory life forms, this is not the case; any fauna species of a suitable size can be classified as a Leviathan.

Although the term "Leviathan" is used to refer to a large mythical aquatic creature in the real world, there is no confirmation on whether the Leviathan classification is restricted to fauna in the Subnautica universe, or is simply the term used for any species of a sufficient size.

Relation to Other Leviathans

Leviathan is not part of a taxonomic classification, so does not imply any of the species classified as such are related. In fact, the only two that appear to have any close relation are the Sea Emperor Leviathan and Sea Dragon Leviathan who share several features including an almost identical body shape, seven identically positioned tentacles dotted with glowing spots, two forelimbs and a pair of light-producing organs atop their snouts. These two most likely shared a common ancestor that has since diverged into a smaller, cave-dwelling predatory species and a larger, planktivorous species residing in the open ocean.

Leviathans of the Past

Despite being enormous when compared to the fauna of Earth, the leviathans inhabiting Planet 4546B in the present day are dwarfed by their predecessors; the three-million-year-old Gargantuan Fossil at full length is estimated to be 6-8 times longer than an adult Sea Emperor Leviathan specimen. To support a predator of such titanic proportions, many of the other creatures of that time period must have also been of colossal proportions.

The one-million-year-old Ancient Skeleton is enormous, with the gaps left by its missing teeth being large enough for Ryley Robinson to swim through comfortably. The exact size of this creature cannot be determined as the body form of the creature is extremely bizarre and it is unknown if the skeleton visible is the entire skeleton. What is available is around 100 meters in length, but it is also extremely bulky, giving it more body mass than anything alive on the planet today.

Known Leviathan Class Organisms

The Crater

Sea Treader: Around 20 meters³; smallest Leviathan
Reaper Leviathan: 55 meters
Reefback: Around 70 meters in length yet also extremely broad, making it one of the largest creatures
Ghost Leviathan Adult: 110 meters
- Ghost Leviathan Juvenile: Around 67 meters
Sea Dragon Leviathan: 112 meters
Sea Emperor Leviathan: 160 - 200 meters
- Sea Emperor Leviathan Juvenile: Around 60 meters
- Sea Emperor Leviathan Baby: Around 1.5 meters

Sector Zero

Glow Whale - 30 meters
Chelicerate - 40 meters
- Void Chelicerate - 65 meters
Shadow Leviathan - 60 meters
Ice Worm - 95 meters
Ventgarden - 110 meters in height
- Juvenile Ventgarden - ~22 meters in height

The Squidshark is stated as "a leviathan-class predator at the smaller end of the scale" by its databank entry, though it is not included within the Leviathan tab in the databank.

Extinct Leviathan Class Organisms

Crater

Ancient Skeleton: Exposed skeleton around 95 meters, full size unknown
Gargantuan Fossil: Around 1,100 - 1,300 meters

Sector Zero

Frozen Leviathan - ~70 meters excluding tail, around 150 meters including tail.

-Another pair of Leviathans that seem to be related are the [[Shadow Leviathan]] and the [[Ice Worm]]. Both of which have elongated serpentine bodies lined with several parapodia, have large distinct blade-shaped heads, blackened skin, and feed with monstrous mandibles. This indicates that they had a common ancestor with a body plan much like that of a centipede crossed with a worm.
