• Atmosphere Independent: The Adult Alien can survive underwater, or in space
without danger of suffocation for an unknown period of time.
• Hibernation: The eggs are known to be able to survive at least 60 years - and
most likely much longer - without damage to the Face hugger inside.
• Motion Sense: Eggs will hibernate until they detect activity nearby at which
time the face hugger will awaken and, if prey comes close enough, the egg will
• Pheromone Communication: Communicates primitively through the use of
pheromones. These pheromones can be used to indicate the location of potential
prey or hosts, emotional state, developmental stage, and hive affiliation.

it's a warning or not, yes?" -Ash (from Alien)
The egg is the most vulnerable phase in the alien's development. Eggs are laid
by the Queen, and are usually produced in large amounts. They standard size is
between 2 and a half and 3 feet, although smaller versions are possible. The
minimum gestation period of an egg from the time it's laid is unknown, given the
rapid maturity of the other phases, it can be speculated that this time period
is quite short. Eggs may lie dormant for years on end, and can be triggered to
open in two ways. The growing "Face Hugger" inside may sense the presence of a
potential host, and trigger the opening itself. Or, the Queen may trigger an
Egg to open by unknown means, possibly pheromones. At that time the egg opens by
peeling open the four "lips" that cover its upper hemisphere.
It has been speculated that when isolated, an Adult Alien is capable of
impregnating a captured victim with an embryo it somehow generates. This seems
highly unlikely and these reports probably come from the fact that the Adult
Alien will capture and cocoon potential hosts when isolated despite the absence
of a Queen or eggs.
