Sea Treader Leviathan

The Sea Treader Leviathan is a passive leviathan class creature. It can be found in small herds on the seafloor, primarily in the Sea Treader's Path but also in the Grand Reef. It is the smallest leviathan in Subnautica.

Appearance

The Sea Treader has three sizes; small, medium and large. Its body consists of a large torso with long, double-jointed back legs. Its front "leg" is, in fact, the creature's elongated snout, which is segmented and foldable for moving around. Its carapace is mostly blue, decorated with bright bioluminescent orange patterns.

The Sea Treader's head features two pairs of large and small eyes. Two large feelers protrude from its underside and extend upwards along either side of its head. These feelers run along its entire body, and end in two bumps at its rear.

An image in the data bank entry shows that Sea Treaders have compound eyes.

Smaller Sea Treaders are often seen following behind larger individuals, which suggests that they are juveniles.

Behavior

The Sea Treader travels in herds, frequently emitting loud, echoing calls. These herds follow predetermined paths throughout the Sea Treader's Path, the biome's large cave system, and along the edge of the Grand Reef.

The Sea Treader may pause to defecate or graze, but never stay in one specific area for long periods of time. When grazing, they place their beak into the ground and move it for a while to munch on seagrass or other flora.

Each time the Sea Treader takes a step, it may spawn 0-3 Shale Outcrops that will slowly sink back into the ground after a short amount of time.

Data Bank Entry

A vast bipedal leviathan which roams the reefs in herds, grazing the seafloor.

1. Antennae: Antennae on the creature's head can detect a range of scents, helping the sea treaders to find fresh grazing pastures, avoid the path of large predators, and sense chemical signals from others of their kind.
2. Carapace: Thick armour protects the creature from attack by all but the largest of carnivores. Two legs extend from the rear.
3. Elongated Snout: Used to siphon up plant material from the sea floor, and maintain balance.
4. Behavior: Large herds would decimate the flora of a single area, thus encouraging the sea treader's migratory behavior. Families keep their young towards the center of the herd, and parents will lash out at over curious interlopers in search of an easy meal.

Assessment: Sea treader herds may unearth mineral deposits as they churn up the sand

Trivia

• Sea Treaders were formerly defensive rather than passive. If the player swam in front of a Sea Treader, it would stomp or kick them, dealing 40 damage. This behavior was removed in the Living Large update.
• Sea Treaders are the smallest organism to be classified as a Leviathan, at 20mx20mx20m.
• The Prawn Suit is capable of standing on top of Sea Treaders.
• Sea Treaders spawn on two paths: the path named after them, and a second path located within the Grand Reef.
• The Sea Treader is immune to the effects of the Stasis Rifle.
• The Sea Treader Leviathan is one of the only two Leviathan Class organisms on Planet 4546B whose eggs are never seen, even with the aid of console commands, the other being the Reaper Leviathan.
• The concept art for the Sea Treader Leviathan can be seen in their Data bank entry.
