It kinda reminds me of the Movie Pitch Black with Vin Desael. where alien bugs live underground, only come out when its dark and are heat seeking.

I wish people would start posting these threads on geological features in the right forum.
Lava Tubes have nothing to do with UFO's and Aliens. Any first year Geology student could identify what that is. Odd how the thread keeps going after the answer was posted on page one.
Explanation: What created this unusual hole in Mars? The hole was discovered by chance on images of the dusty slopes of Mars' Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars. The hole appears to be an opening to an underground cavern, partly illuminated on the image right. Analysis of this and follow-up images revealed the opening to be about 35 meters across, while the interior shadow angle indicates that the underlying cavern is roughly 20 meters deep.

That does not mean something wouldn't use it for some purpose, animals in the wild on our planet do the same thing (inhabiting man made or natural formations).
