True-Finn-Fan first off... are you 100% sure this is a pic from mars... i seems odd that NASA would leak pics... and it doesn't look like the mars landscape secondly if this is from mars the thing is probably just a compound or a rock that looks similar to a rat... i saw on Perception, the human mind looks for patterns in everything we see... this is the pattern of a rat. that and there is no way a life form of that size could survive on mars due to the lack of nutrients and the fact that to be any larger than a bacteria you need Aerobic Respiration... mars has no oxygen so Aerobic Respiration could not occur. therefor a creature of that size could not survive on mars.

taini someone in NASA did leak it against orders. I don't know if they know who did it. ever since the photo was leaked NASA has been paranoid to tell the people that it is probably nothing. they fear that we will freak out or get out hopes up. if you think about it the species on other planets might not need what we need. maybe they can live without oxygen? to answer your first question...yes this is an actual picture of Mars. like I said someone leaked it and people began to notice the rat like thing. NASA noticed it themselves while analyzing the photos. whether it's life or a compound...we might never know.

True-Finn-Fan ^only way to survive without Oxygen (so far) is to do Anaerobic Respiration... it is terribly inefficient and therefore can not support creatures that are larger than bacteria... not only that but a creature like the one in the photo could not survive without carbohydrates... which are not present on mars. (learned this in biology)

ShadowFan100 I really doubt it's real. If it were a real pic, don't u think it would look more clearer than THAT? Can't even tell what it is.
