Biomes

Subnautica features a wide range of Biomes to explore and coexist with, which represent miniature ecosystems from the real world.

There is a very diverse range of Biomes, from the vibrant Kelp Forest to the sizzling depths of the enigmatic Lava Lakes. Each Biome contains its own set of Flora and Fauna to discover and resources to harvest.

Trivia

 * Developers' footages of biome generation can be seen on a playlist from Russel Maekim's YouTube channel.
 * The game considers the inside of an Observatory, Lifepod, and Scanner Room to be separate biomes. This is also true for the Aurora and for some of the large wrecks in the Bulb Zone and Grassy Plateaus (labelled crashedShip and wreck, respectively).
 * Early biome concepts included Crystal and Arctic biomes. Considering the Arctic has since gained a development work-sheet, it might be added in future updates after the release of the official game.
 * Early surface biome concepts were divided into Kelp Forest, Dense Kelp Forest, Sunny Kelp Forest, Coral Reef, Danger Reef, Safe Shallows, Grand Reefs, and Floating Island. Four of these have since been fully developped/implemented (Safe Shallows, Kelp Forest, Floating Island, Grand Reef and Deep Grand Reef).
 * Early lava zone biome concepts were divided into Lava Zone, Lava Bridges, Inactive Lava Zones and Thermal Vents. These were all implemented in some form, though the Thermal Vents have been reduced to geological features rather than a full biome.
