As NASA rover droid Curiosity drilled into the surface of Mars to take samples, a footage was allegedly filmed by it of a food chain in action. Mars Alive, a YouTube channel that looks for proof of life in NASA photos and videos, has posted a footage from Curiosity in Mars which apparently has a clip where a small alien creature feeds on a smaller creature.

The video was titled "NASA What Has Curiosity Rover Detected Here? Explain!!"has since gathered a number of views. Scott C. Waring of ufosightingsdaily.com, a known UFO chaser, concurs it is evidence of alien life.

He blogged, "Here you see the Curiosity rover drilling into the dirt on Mars and as it is, a small critter is seen walking away from the drill area. To top it off, the small creature walks just a little way, before something even bigger stretches out from below a rock and snags it."

Mr. Waring added his own theories to his comments and claims that the video showed a sharp triangle rock that might have been a camouflage for a crab-like creature. He also said that six years ago, on a footage, a big rock was seen to have moved. He further stated that Russian's lander produced pictures where a crab-like creature was seen in one and was gone in another.

Reactions to the posted video were mixed. On another post on YouTube, Terry O'Neill said, "Looked like an insect to me. I could see legs."
