Reefback Leviathan

==Summary==
The Reefback is a leviathan class fauna species found in Subnautica. They are the second biggest passive species in the game, feeding only on microscopic plankton filtered from the water, and tied with the Sea Dragon Leviathan for second largest overall.
Reefbacks are usually seen moving in herds of more than two individuals. They frequently emit low frequency calls that can be heard for miles, suggesting that they fill a similar ecological niche to Earth whales, despite being invertebrates.
The Reefback's most striking quality is their ability to support mini-ecosystems on their backs, with numerous flora, coral and barnacle species having planted their roots in the ancient scars of it's hard chitin. This, coupled with faster herbivores that come to graze on them makes each Reefback a vibrant microcosm "worthy of years of study in itself".
==Powers and Stats==
Tier: Likely 
Name: Reefback Leviathan
Origin: Subnautica
Gender: Hermaphrodite
Age: Varies
Classification: Aquatic Lifeform, Leviathan Class Filter Feeder
Powers and Abilities: Superhuman Physical Characteristics, Underwater Breathing (Type 1), Large Size (Type 1; Around 70 meters in length, though also extremely broad), Bioluminescence, Longevity (Adult Reefbacks are likely extremely old, as their lifecycle can likely go on for several centuries should they survive their initial growth phase), Likely Echolocation, Resistance to Poison and Acid (Immune to Gasopods' Gas Pods)
Attack Potency: Likely Small Building level (Their sheer size should warrant this as they dwarf even Reaper Leviathans in size and mass, despite their low speed)
Speed: Below Average Human (Can usually be easily outmaneuvered by Ryley Robinson with a Seaglide, or even just regularly swimming), possibly higher in short bursts (If exposed to damage, they will boost their speed slightly for a short period of time)
Lifting Strength: Superhuman (Simply moving their sheer weight around should qualify for this. Can effortlessly carry what should be tons worth of plant and animal life that has taken up residence on their backs)
Striking Strength: Likely Small Building level
Durability: At least City Block level, possibly higher (Their PDA entry suggests that the reason they have grown far larger than any other herbivorous lifeform on 4546B is because whatever could breach their hard chitinous shell has long since gone extinct, making them likely invulnerable to attacks from Reaper Leviathans and even Sea Dragons.)
Stamina: Likely High (Does not seem to ever rest in a conventional sense)
Range: Several meters melee range
Standard Equipment: None
Intelligence: High Animalistic (The PDA makes notes of it's social nature and how it's behavior is consistent with low-level sentience)
Weaknesses: Does not have any fighting instinct, preferring to run if threatened instead. Has no discernible eyes, though their echolocation could potentially make up for this
