Fun:Carbonated lifeform

Carbonated lifeforms, also known as sparkling lifeforms, fizzy lifeforms, and lifeforms with gas, are plain lifeforms into which carbon dioxide gas has been dissolved. Since no life has been observed that is not carbonated, it is sometimes assumed in astrobiology that life elsewhere in the universe will also be carbonated. This assumption is referred to by critics as carbonated chauvinism.
