The Facehugger is the parasite inside the egg. When a host comes in close proximity to the egg, the parasite launches itself out with uncanny accuracy. On a rare miss, the parasite can chase the host to position itself for another launch. Once on the host, the facehugger uses its rubbery tail to squeeze the victim's neck and force him to gasp for air. Its eight spider-like digits wrap around the victim's head and secure its position. In a matter of seconds, the victim is quelled into a comatose state while the parasite forces a tube down his throat. During this phase, it's important that the host be kept alive. Wind bags on the sides of the facehugger pump oxygen through the tube while an embryo travels down into chest cavity. When the process is complete, the Facehugger releases itself from host's body and dies. The host soon regains consciousness with no recollection of the implantation process. The embryo develops quickly and upon maturity forces itself out of the host's chest. This causes an extremely painful and violent death for the host. The facehugger is designed to procreate. It wards off attacks with concentrated acid for blood and strangles the host with its tail if there is any attempt to remove it. It's skin has an outer layer of protein polysaccharides that allow it to shed its cells and replace them with polarized silicon. This gives it a stronger resistance to harsh environmental conditions. So far, no known species is resistant to the Facehugger. Known hosts have ranged from the alien in the derelict craft, humans, and a dog. It is believed that the alien Queen originates from a "Super Facehugger," which is a larger, faster, and a more heavily armored version of the parasite.
