methane

So if you had a methane sea What chemical reactions could occur to support or create life, or just as it has been adapted to live in oxygen what else could it be adapted to live in
 
Biology news on Phys.org
Methane becomes liquid at -260 degrees F. That temperature would hinder the formation of life as we are familiar with it. Oxygen becomes liquid at -297.3 degrees F. If there were more than a 37 degree F temperature drop on a planet with methane seas then the oxygen would become liquid. This planet wouldn't have much of an atmosphere at all.
