Washington: Mars Curiosity Rover has captured the image of a rock that somewhat resembles an iguana.
The iguana doppleganger was first spotted by the website UFO Sightings Daily who found the photograph on NASA`s archives of dozens of images of the barren landscape surrounding the Curiosity Rover, Fox News reported.
The reptile-shaped rock is not the first "animal" to be found on Mars. A rock shaped like a rat was discovered earlier this year.
UFO Sightings Daily coordinator Scott C. Warring told Canadian news site agoracosmopolitan.com that this is not the first animal found on Mars, as there actually have been about 10-15 to date.
He has even found a rock that moved four times in four photos, which then vanished on the fifth.
