Extremophile.
Mix of invented or existing life beings that live or have lived in extreme conditions and have adapted their body to it. For a game that tries to give information about less known real beings in the Earth, and explorations about how could look some probable life beings making designs based on astrobiologic recommendations.
I hope you could identify which of them are from Earth and which are invented. Also, some illustrated species of the Earth are extinct.
