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 head, mouth and/or "beak", also segmented and foldable for moving around.
The Sea Treader's head features two pairs of large and small eyes. Two large feelers protrude from its underside and extend upwards, growing on either side of its head. These feelers run along its entire body, and end in two bumps at its rear.
The Sea Treader's main body is mostly blue, decorated with bright bioluminescent orange patterns.
An image in the data bank entry shows that Sea Treaders have compound eyes.
Smaller Sea Treaders also appear from time to time, being smaller versions of the adults and following 1-2 of them at a time, suggesting that they are infants.
The Sea Treader walks slowly and passively around its paths, constantly emitting loud, echoing calls. If the player tries to swim in front of it, the creature will attack them by pecking or swinging its beak, removing 40% of their health bar.
Sea Treaders often gather into herds, keeping the smaller ones in the middle of the pack, while the larger ones stay on the outside.
Sea Treaders occasionally stop on their track to either defecate (dropping its feces in the process), or to graze. They will place their beak into the ground and start moving 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.
Sea Treader herds tend to migrate between the fields within the Sea Treader's Path, never staying in any specific area for long periods of time, as well as traveling through the large cave located in the Sea Treader's Path.

Assessment: Sea treader herds may unearth mineral deposits as they churn up the sand
- Sea Treaders are the smallest organism to be classified as a Leviathan.
- The Sea Treader's feelers visually resemble those of real life squids.
- The way Sea Treaders move in herds is similar to that of real-life elephants.
- 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 appearance of the Sea Treader strongly resembles Half-Life 2's Strider.
- The Sea Treader likely was inspired by the deep sea Tripod Fish and/or weevils.
- 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.
