Biome
Biomes are regions on any Asteroid or Planetoid, with each containing anywhere from 2 to 11 Biomes. Some biomes can only be found on specific worlds, and some biomes are completely missing from games generated with certain settings
General
There are 22 different biomes in the game. Each biome contains different resources, critters, and plants, and are mostly separated by veins of 
Abyssalite 
or 
Granite 
.
Although each biome has a color shading applied to it that stays after the biome is mined out, there are no special properties beyond the contents of the biomes. (As an example, the Tundra Biome does not cool itself, only starting out cold and cooling through Wheezeworts, which can be removed).

The location of each Biome varies depending on the Asteroid or Planetoid. See corresponding world pages for more details.
Biome Descriptions
Base Game
Sandstone Biome
Commonly refered to as the Temperate Biome, it is one of the possible starting biomes. It contains helpful early-game materials such as 
Water 
, 
Dirt 
, 
Algae , and 
Coal 
. It also contains both early-game plant species; Mealwood and Bristle Blossom. The Shine Bugs and Hatches that are found here also also useful critters for a colony just starting out.
Forest Biome
One of the possible starting biomes. It is a more challenging biome to survive in compared to the Sandstone Biome given less Water and the complete lack of Algae and Coal . The Oxyfern plants generated here are capable of turning 
Carbon Dioxide 
to 
Oxygen 
; although this oxygen generation is often insufficient to sustain a colony permanently. The presence of both Arbor Trees and Pips make early food production with Mealwood far more sustainable
Given there are less resources that are immediately useful to the player; branching out to other parts of the Asteroid is encouraged.
Barren Biome
A great early source of 
Refined Iron 
and Coal , the biome is rather barren beyond this; completely lacking life of any sort.
In 
; some variants are more similar to variants of the Forest Biome than the Barren Biome; generating with 
Aluminum Ore 
, Pips, and Arbor Trees.
Tundra Biome
A frigid biome made primarily of 
Snow , Ice , and 
Polluted Ice 
. Sleet Wheat and 
Wolframite are also found here; and are incredibly useful. Wolframite is a precursur for the highest melting point metal in the game, and the highest overheat temperature modifier in the game; while Sleet Wheat is an excellent source of both early and late-game foods.
The Anti Entropy Thermo-Nullifier can also be found here; which comsumes 
Hydrogen and deletes heat while running.
Jungle Biome
Commonly refered to as the Caustic Biome, this is the home of the Drecko and Pincha Peppernut. Drecko's are an excellent source of 
Reed Fiber and 
Plastic 
. Pincha Peppernuts are a required ingredient in many late-game food options; notably Spicy Tofu and Pepper Bread. The atmosphere here is a mix of 
Chlorine 
and Hydrogen; both potentially very useful; especially in deep freezers.
Magma Biome
Appears at the very bottom of several asteroids or when specific World Traits are present. It contains large amounts of Magma 
, 
Obsidian , and small amounts of 
Neutronium which cannot be destroyed.
Marsh Biome
Filled with 
Polluted Oxygen , Polluted Water , and Slimelung-infested 
Slime , this biome is also an excellent source of 
Gold Amalgam 
.
This biome is filled with organic material. Plenty of Algae along with all the Slime ; its also home to Pacu, Pufts, and Dusk Caps. The Thimble Reed plants are one of the primary ways of obtaining Reed Fiber.
Ocean Biome
Commonly referred to as the Tide Pool Biome, this is the home of the Pokeshell. 
Fossil , Sand 
, and 
Salt Water 
are very common here. There is also 
Sedimentary Rock here; which can be used to increase the chances of Hatches laying a Stone Hatchling Egg. Waterweed can be found here; which is required in the production of Frost Burgers.
Oily Biome
Often located near the bottom of the map; this biome is the primary source of 
Crude Oil 
; which is a precursur for several useful materials which will greatly help with game progression. Slicksters are also found here; which turn Carbon Dioxide into Oil. This biome is dangerous; the heat can easily scald Duplicants and the germs released by the Sporechids here can cripple a duplicant for several cycles.
If the asteroid has Irregular Oil World Trait during world generation, the Oily Biome may appear anywhere in the map.
Rust Biome
A chilly biome full of 
Rust , Iron , and Chlorine . Depending on variant, a wide range of plants and critters can be found; notably Nosh Sprouts and Dasha Saltvines; which are exclusive to this biome. The Rust in this biome can be combined with salt to produce Oxygen ; great for when other options are impractical or impossible.
Space Biome
The surface of every asteroid. In the base game; it contains 
Mafic Rock , 
Regolith , and Granite in the upper layers, and Igneous Rock can be found in the lower layers. In the surface makeup of planetoids varies greatly between planetoids.
Meteor Showers can randomly happen and bring several useful materials to the asteroid.
Gases and liquids are sucked into the vacuum of space through the open background, deleting them, and in the absence of gases heat can not dissipate from materials and objects. Adding Drywalls helps to construct rooms that can hold air and liquid.

Swampy Biome
One of the possible starting biomes; this biome is filled with Polluted Water and Polluted Oxygen . With the amount of off-gassing materials that make up this biome, like 
Polluted Dirt and 
Polluted Mud , keeping a breathable atmosphere for your Duplicants is not difficult. Its important to note that the off-gassing does consume the tile it emits from; slowly. This can cause pools of liquid to suddenly open up and spill into unwanted areas as natural tiles disappear.
With Pacu spawning here; its also relatively simple to set up food production; and get a considerable amount of 
Lime in the process.
Aquatic Biome
Found exclusively on the Water Asteroid, it is the only source of 
Graphite , a resource used in the production 
Fullerene 
, which itself is the precursor of 
Super Coolant 
. The Biome is drowing in Water making traversal difficult and atmo Suits a requirement to get to any reasonable depth. Lime is also found in large amounts here.
Metallic Biome
A large source of metal ores; notably Gold Amalgam . Also contains useful amounts of Dirt , Coal , and 
Oxylite .
Moo Biome
Found exclusively on the Moo Asteroid, it is the only biome where Gassy Moos and Gas Grass can be found. The temperature is cold enough to freeze chlorine; and there is no naturally available breathable gas.
Niobium Biome
Found exclusively on the Superconductive Asteroid, it contains the only source of 
Niobium 
.
Radioactive Biome
A frigidly cold biome able to freeze Carbon Dioxide and Chlorine and in some cases even cause Frostbite; it is the only source of Beetas and thus the best conversion ratio of 
Uranium Ore 
to 
Enriched Uranium . This biome is also a source of Wolframite .
Regolith Biome
Found exclusively on the Regolith Asteroid. Outside of Classic Starts; this is the only place where Shove Voles can be found.
Wasteland Biome
The home of the Divergents and the symbiotic Grubfruit Plant. The wasteland features a breathable atmosphere; making exploration easy; and is also filled with 
Sulfur 
; making ranching and cultivating the plants and critters here simple; although sustaining this will require a Sulfur Geyser at some point. There is also a diverse set of minerals contained here; which is unusual for biomes with most only having just one; not including the biomes border.

Ice Cave Biome
The starting biome for every Ceres start. It contains large amounts of Snow and Ice , with plenty of Oxylite spread about. The temperature means Water for research is difficult to obtain without an Ice Liquefier as melting the biome itself isn't recommended due to Liquefiable materials making up a vast majority of the biomes tile count and mass. The biome also contains both Pikeapple Bushes and Floxes; useful for 
Wood and 
Phosphorite 
generation in the cold.
Cool Pool Biome
The Ceres alternative to the Jungle Biome. With a source of 
Iron Ore and Reed Fiber; its essential to exploit this to progress in the bitter cold. It also contains 
Sucrose 
which can be useful when ranching Spigot Seal.
Nectar Biome
The Ceres alternative to the Oily Biome. It is dominated by frigid cold temperatures and is the home of the Spigot Seals and Bonbon Trees. 
Nectar from the trees can be turned into plastic directly though a Polymer Press or into 
Ethanol 
through Seal ranching.

Garden Biome
The starting biome for every Relica start. It contains a variety of basic resources, including Water , Dirt , and 
Peat . It also has several unique plants, including sprawling Ovagro Vines, Sweatcorn, the unusual Mimika Bud and their Mimikas, and the non-propogating Snactus, and is also home to the Lumb. It is warmer than most starting biomes.
Feather Biome
The Relica alternative to the Jungle Biome/Tundra Biome. It has caverns filled with Chlorine , which are inhabited by Rhexes and their prey Dartles, which eat from the Dew Dripper plants. Chlorine-consuming Megafrond plants also grow here. This biome has cold temperatures and large deposits of Iron Ore .
Wetlands Biome
The Relica alternative to the Marsh Biome/Oily Biome. It shares much in common with the Marsh Biome, including the lakes of Polluted Water and their resident Pacus, the warm temperatures, and deposits of Gold Amalgam , which are sparsely present in this biome. Unlike the Marsh Biome, there is an absence of Slime , Thimble Reeds, and Pufts, instead being home to the carnivorous Jawbo, irritating Gnits, 
Amber 
-producing Luras, and aquatic Seakomb, an important industrial ingredient.
