how do these creatures see???where are there eyes if there have any???do there hear to find there way like a bat???,are there telapathic???are the facehuggers blind & reley on sound vibrations to locate the host??just wondering so i thought i'd post them..how if there do see?how do there see the pred when cloaked hence why i think its by sound..found this little bit of info on Alien wikipedia,"They have elongated, cylindrical skulls but possess no visible eyes, though in the original Alien film, the top of the creature's head was translucent, with empty eye sockets of human appearance visible within. This element was re-used for the "Predalien" 29 years later. How the creatures see is uncertain. In Alien 3, a fisheye lens was used to illustrate the alien's point of view. In the novelization of the movie Alien, the creature is held mesmerized by a spinning green light for several minutes. "this confused me even more as it states the sockets where empty....mmmmmm holmles i need some deduction here?
