A Japanese blogger claims that he has found what looks like a Lizard in one of the photos that NASA has sent back from Mars.

He posted the picture online at UFO Sightings Daily and has received quite a bit of attention since.

The site believes that the image was found in March, but NASA is dismissing the lookalike as a rock.

What do you think?  Lizards on Mars or just an interesting looking rock?  Check out the full gallery of pictures here.
