Another image from the Mars Curiosity Rover has alien believers excited. This image looks like a lizard, RT reports.

A raw image taken from Curiosity caught the attention of a Twitter user. The user then sent it over to UFO Sightings Daily, a popular alien website that follows possible UFO sightings.

"The creature looks like a lizard, but with a short tail. I tried hard to get a close up of it. The head is shiny and looks like it has an outer shell on its head, but its body, arms and legs look like they do not have an outer shell, but a skin," UFO Sightings Daily contributor Scott Waring wrote.

Waring says the features of the creature are very easy to make out, it has two upraised eyes on its "head" and its eye is "dark and has a raised brow ridge."

"Its head is cocked in such a manner that shows us it is on high alert over the rover's presence," Waring says. Waring hopes that NASA will change its viewing angle of the rover to get a better look at it.

Waring wonders with all the latest evidence of creatures on Mars, why NASA is not investigating these suspected creatures further.

UFO followers have spotted several odd creatures in recent times thanks to all of the photos being provided by the Curiosity Rover to the NASA website.

Earlier this month, social media users spotted a crab-like creature that they called "Spider." "Alien," "John Carter," and "awesome Martian space crab."

After that creature was spotted, a woman-like figure was found with breasts and long hair. The woman appeared to be wearing a cloak and looked like she was actively "watching" the rover from a distance.

Skeptics belief these creatures and objects found on Mars are simply people's eyes playing tricks on them.
