Eggs are items found in Subnautica and Subnautica: Below Zero. They are the unhatched versions of their respective Fauna. Until they hatch, an egg is labeled as an unknown creature egg, changing to match the name of the creature the egg contained if it hatches inside an Alien Containment. The PDA gives the player this information instantly no matter where they are, without needing to be present to observe which creature came from which egg. After learning this information this way in-game, or from the table below, similar eggs can be identified by the biome it comes from, its appearance, and size.

Almost all eggs can be placed inside an Alien Containment. After placing an egg inside an Alien Containment, it will stay where it was placed. After one to three in-game days, the egg will hatch into a smaller version of its respective species. The hatched creature will slowly grow until it is moderately-sized or can fit within the confines of the Alien Containment. They can die inside of the aquarium, however, if the aquarium's population limit is surpassed.

Baby creatures can be picked up and placed outside in the water, where they will instantly become fully grown. Most normally aggressive creatures will not attack the player if hatched in the Alien Containment, allowing the player to scan it even after it is released in the wild. The exceptions are the Ampeel, as its electric shocks still apply damage, and the Crabsquid.

Eggs can be destroyed. Hits with a knife will slice open the egg, resulting in no creature being spawned. Crashfish explosions can destroy their own eggs and habitat if they are too close. They are destroyed by a Prawn Suit with a punch, or using a Propulsion or Repulsion Cannon on it, meaning they cannot be picked up with a Prawn Suit or moved around with tools, only by hand.

Eggs can be found in their species' biomes, but gravity can cause an egg to roll or fall into another biome or cave. An example of this is finding a Stalker egg in the Jellyshroom Cave.

Eggs can be used as fuel for the Bioreactor, though they provide far less energy than a hatched creature.

Egg Details Location
Sea Dragon Egg Transparent

Sea Dragon Leviathan Egg

An egg found in a specimen case within the Disease Research Facility, this egg was taken by the Precursors one thousand years ago to help research ways to make the Sea Emperor Leviathan eggs hatch. This egg cannot be hatched.

Two more Sea Dragon Leviathan eggs can be found in the egg lab of the Primary Containment Facility, strangely, these eggs are far smaller than the egg found in the Disease Research Facility.

SeaEmpEgg

Sea Emperor Leviathan Egg

Six of the eggs laid by the captive Sea Emperor Leviathan in the Sea Emperor's Aquarium. These eggs must be hatched in the story. One of the eggs was taken and forcefully cut open in hope of learning about the hatching response the eggs needed. It can be found upstairs in the Primary Containment Facility along with the dead fetus from the egg on a research table.
Ghost Leviathan Eggs

Ghost Leviathan Egg

The eggs of the Ghost Leviathan, which were placed down when the Giant Cove Tree was an infant, and now it has grown around the eggs and formed a natural protection over the eggs, awaiting them to hatch. These eggs cannot hatch in-game.

Databank Entry[]

Alien Eggs

Evidence suggests that a substantial number, if not all of the local species reproduce through egg-laying. Eggs can be found resting on the seafloor, buried beneath detritus, or even wedged into cracks in the rock.

Different species likely favor different biomes as their nesting grounds. Eggs discovered in the wild are in some form of natural stasis, likely awaiting ideal conditions in which to hatch, or the delivery of some vital enzyme which will kick start the process.

It is impossible to calculate the species of the egg from the exterior, however it may be possible to stimulate a hatching response if an egg is relocated to a suitable alien containment unit.
