BioEden Animals Database

How to read this table. Every value marked *Confirmed* is transcribed from an official BioEden screenshot or the Steam store page. *Partial* means the animal and its DNA cost are confirmed but its climate band is not yet documented. *Named only* means the species appears in a Collective Request in official material but has no published stats. We would rather leave a cell empty than fill it with a guess — if you are planning a dome around a number, you need to know where that number came from.

How the BioEden Bestiary is organised

The Bestiary is the screen where every BioEden animal lives. It is split by biome across six tabs — Forest, Jungle, Prairie, Savannah, Tundra and an all-species view — and each tab shows a grid of species cards. Card colour is doing real work here and it is worth learning:

• Blue header — the species is already unlocked and can be incubated right now. Landowl and Ributs start

in this state in the Jungle tab.

• Green header with a DNA number — available to unlock, and the number is the exact DNA fragment cost.
• Grey header — gated behind something other than DNA, usually research progress. Thudder is grey in the

Jungle tab despite showing a 20 DNA price, which is why players who save up 20 fragments early are confused when they still cannot hatch it.

Selecting a card opens a requirement panel on the right with three tabs: Biome, Residency and Mating. Those three tabs are three separate checklists, not one. An animal can be perfectly happy in your dome under the Biome tab and still refuse to become a resident, because Residency asks for things Biome does not.

What each BioEden animal actually needs

Reduced to essentials, every species in the BioEden game cares about five things:

1. Temperature band. A minimum and maximum in degrees. Landowl accepts a very wide 20–45°, which is

exactly why it is the tutorial species. Later species narrow that window sharply.

1. Humidity band. Same idea, expressed as a percentage. Landowl wants 55–90%.
2. Required plants. Listed as *Animal and Plant Required* on the card. Landowl needs two Ferns. Plants are

placed from the dome build palette and count as both food and habitat.

1. Decoration. A general measure of how furnished the dome is. Rocks, burrows, water features and plants all

contribute.

1. Diet, and who else is in the dome. This is the requirement the Bestiary does not put a number on, and the

one that ruins the most domes. See carnivores vs herbivores.

The three stages every animal moves through

Every BioEden species progresses through the same ladder, and each rung has its own requirement list:

There is also a Shining Status referenced in official Collective Requests — the Mystic Guild asks you to “raise Scroftusk to Shining Status”. It reads as a per-species prestige state above Mating, but its exact requirements have not been published, so we have not invented any.

Where DNA fragments come from

DNA is the hard currency of the BioEden Bestiary and it is deliberately scarce early. You get it from surveying and salvaging out in the world, from research, and from Collective Requests. The practical consequence is that your first ten hours of BioEden are a budgeting exercise: a 3 DNA Fimble and a 5 DNA Slink together cost less than a single 10 DNA Mirra, and three cheap species in a stable dome produce far more progress than one expensive species in a dome you cannot yet climate-control.

Help us finish this database

The Jungle roster is documented because it appears in official screenshots. The Forest, Prairie, Savannah and Tundra rosters are not yet public. If you are playing BioEden and can screenshot a Bestiary card with its temperature, humidity and plant requirements visible, send it over and it goes into this table with a credit. That is how this page gets finished — not by guessing.
