Xenomorph (Xeno-Earth)

The Xenomorph is an alien species that resemble more like an animal than a human. When a xenomorph spots its pray, it will become very hostile in its efforts to either feed on it or reproduce with it. It has an exo-skeleton like an ant which means it has skin like thin armour so it isn't easily hurt. Its eyesight is not as good as our own but makes up for it with other hightened senses.
