The Ghost Leviathan is a life form belonging to the fauna category. It is currently the second largest aggressive creature of Subnautica, and the third largest overall. Five Ghost Leviathans currently spawn in-game: two juveniles in the Lost River (one in the Ghost Forest and another in the Bones Field) and three adults, two of which spawn in the Grand Reef, and one in the Northern Blood Kelp Zone.

The Giant Cove Tree is the nesting ground of this leviathan species (although they are not present around the tree), with its massive glowing bulbs being their eggs. The Ghost Leviathans' life cycle begins in the Lost River, as juveniles. As the leviathans mature and become too large for their home, they migrate to the open, surface world biomes such as the Grand Reef and Blood Kelp Zone, until eventually migrating to the Void, continuing to grow and roam freely in the open water.[1][2] Despite being much smaller than the Sea Emperor Leviathan, its eggs are far larger.


The Ghost Leviathan has a transparent outer covering, over a blue inner body which features many dark blue stripes, four yellow, bioluminescent eyes as well as six small fins on the torso section. A small, decorative sail sits on top of the head, and two long structures protruding from either side of its head which bear similarities to the blades of a hammerhead shark. It has a rectangular mouth with a glowing barble beneath and a long body that tapers to a point. The outer body is transparent, allowing the smaller, inner body to be viewed. The inner body is long and thin, with multiple small protrusions tipped with bioluminescent orange spots. Unlike the outer body, the inner body has a distinct neck that is very thin and joins the head and body. It is also slightly longer than the Reaper Leviathan if it is in the Lost River, and roughly twice the size when in the Void and Grand Reef.


The Ghost Leviathan, when it identifies a player or vehicle, will open its mouth and charge. The player will take 85 damage from this.
