The {{w|Atmosphere of Mars|atmosphere of Mars}} is far too thin for us to breathe, or indeed, to extract any oxygen at all in our lungs. It has on average only around 0.6% of the pressure of Earth's atmosphere, and it is mainly carbon dioxide; only 0.146% of that is oxygen. Yet the result of their modeling was clear. ThroughoutIn the surfacecold ofconditions on Mars these minute amounts of oxygen can get into salty seeps of water that may be present there. What's more, salty water anywhere on Mars can take up areenough possibilitiesoxygen for microbial life that depends on oxygen, and in polar regions, perhaps 6.5% of the Martian surface, there may be enough oxygen for simple animals such as sponges.
 
This is especialy interesting because of the relevance to multicellular life, even multicellular animal life such as those simple sponges. Some life forms can survive without oxygen, but oxygen permits more energy-intensive metabolism. Almost all complex multicellular life on Earth depends on oxygen.
