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. Six Ghost Leviathans currently spawn in-game: three juveniles in the Lost River (one in the Ghost Forest, one in the Bones Field, and a third in the Mountains connection) 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. According to PDA scan entries of the Cove tree, the eggs were laid there when the tree was small, and it has grown around the eggs to protect them. 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 Dead Zone, 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.

A single Ghost Leviathan spawns when the player enters the Dead Zone. If the player is still in the Dead Zone thirty seconds later, a second Ghost Leviathan will spawn, another thirty seconds and a third will spawn, the number that can be spawned at one time is capped at three. They will swim back into the Dead Zone and despawn when the player leaves the Dead Zone.


The Ghost Leviathan has a soft, transparent outer membrane covering a muscular, blue, inner body which features many darker blue stripes, four yellow, bioluminescent eyes as well as six, possibly vestigial 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 barbule lure beneath. Its long body tapers to a point.

The outer body is transparent, making the smaller, inner body visible. The inner body is long and thin, and covered in pulsating, bioluminescent orange stripes with many orange tipped protrusions ending with blinking bioluminescent orange glows. Unlike the outer body, the inner body has a distinct, thin neck joining the head and body. As the leviathan moves through the water, it leaves trails in the water behind it.


To attack a target, it will spiral up and charge. When charging, it will open up its mouth and make a loud, echoing screech. If it successfully attacks, it will do 85 damage to the player and swim some distance away, as if losing interest.
