Xenomorph

The Xenomorph was a parasitoid extraterrestrial species.Biology

Xenomorphs were a little-known parasitic reptilian species. In order to breed, a larval Xenomorph, hatched from an egg, would attack a mammalian host, such as a Human, and implant an embryo in the host's digestive tract. Over the span of several standard hours, the embryo would begin to grow and the original larva would die. When gestation was complete, the baby Xenomorph would burst out of its host, killing it in the process. As someone once said, "She'll breed. You'll die." Within a matter of days, the embryo developed into a full-grown Xenomorph.Fully grown Xenomorphs showed many biological similarities to the creatures which they grew within. For example a Xenomorph gestated within a dog or cat might move around on all four legs.Xenomorphs were excellent swimmers and extremely fast.Xenomorph society existed as a hive, controlled by one queen. On average, the queen was twice as tough as the drone Xenomorphs that served her. She could use her tail to spear victims and naturally camouflaged herself with wall-coating secretions.In fact, the drones are greatly stupid compared to their Queen, they have showed greater intelligence such as opening doors.
