s- that is, the aliens
from the movie Alien
and its sequels- are partially so named because they pass through an insectile
variety of forms during their life cycle
. Having just finished watching the movie, I decided to node what I now know
. And so, it all starts like this...
The Xenomorph starts out as an egg
. It does, in fact, bear some resemblance to a terrestrial
egg, being oval
in shape, but instead of cracking open, a sort of seal
at the top opens into four 'petals
'. These eggs are very durable
, and the embryo
inside can remain viable
amounts of time.
The first stage of the newly-hatched
Xenomorph is the facehugger
. This name is rather self-explanatory
, since the first stage involves leaping from the egg to latch onto a host
's face, wrapping itself around him and inserting a tube
into his throat. The host (if human
, at least) enters a coma
, in which he stays until time for stage two.
This stage, stage two, is a very brief sort of commensalistic symbiosis
. The facehugger has fallen off and die
d, leaving a sort of embryo inside the host. During this stage, the host awaken
s from his coma and eats as much as possible until the Xenomorph has enough energy
for stage three.
During stage three, the Xenomorph 'hatch
es' from its host and begins to grow into its adult
form. Like stage two, it spends relatively
little time in this stage, having already gather
ed most of the requirement
s for full growth. Stage three begins with the Xenomorph erupt
ing rather violently from within its host, then attempting to find a safe place to grow.
This is the stage that most common
ly comes to mind when thinking of a Xenomorph. It's basically a humanoid
, taller than most humans, with an elongated, eyeless head
(though perhaps containing some sensory organ
-tipped limbs, and a long prehensile
