Eggs

Eggs are items found in Subnautica. They are the unhatched versions of their respective Fauna. Until they hatch, the egg will be labeled as an unknown creature egg, changing to match the name of the creature the egg contained once it hatches. An egg can be identified by where it was found, its appearance, and its size (see table below).

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 mildly full sized or can fit to the confines of the Alien Containment. They can die inside of the aquarium however, if the aquarium's population limit is surpassed, or if they are left unattended for too long.

Baby creatures can be picked up and placed outside in the water, where they will instantly become fully grown. An aggressive creature will not attack the player if it is hatched in the aquarium, allowing the player to scan it even after it is released in the wild.

Eggs are also capable of being destroyed before they hatch. 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 can also be destroyed by a Prawn Suit with a single punch. Blasting an Egg using a Propulsion Cannon or Repulsion Cannon will result in their demise.

Eggs can be found in their species' respective Biomes, however, due to the game's physics in the game engine, an egg can roll into another biome or cave. An example of this is finding a Stalker egg in the Jellyshroom Cave.

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

More information and animations can be found on Trello.
