GalCiv4:Citizen Biology Table
| Name | Description | Effects |
|---|---|---|
 Aquatic
|
Aquatic species live most of their lives deep in the oceans, giving them access to several unique Aquatic Techs. They can colonize Oceanic worlds with no penalty. |
|
 Silicon Based
|
Silicon lifeforms are built from rocks and rare minerals. They have no need for food, though their Growth is slow unless they have access to plentiful amounts of Promethion. |
|
 Ammonia Based
|
Ammonia lifeforms thrive on volatile gases and complex nitrogen compounds. While they do consume food, their growth rate significantly accelerates in environments rich in pollutants. |
|
 Carbon Based
|
Carbon-based species use water and hydrocarbons as the basis of their chemistry. Their populations require food in order to grow. |
|
 Synthetic
|
Synthetics are robotic lifeforms that do not require food to survive, and can operate in a variety of environments. Unlike squishy organic species, Synthetics fabricate their population and can grow virtually unfettered. |
