Xenomorph/Alien

A Xenomorph's physical appearance can vary widely depending on its life stage, hive, caste, age, and host. Its ability to incorporate genetic material from its host, coupled with the existence of numerous mutations and deviations which have originated naturally or artificially; makes the Xenomorph one of the most phenotypically diverse organisms in the galaxy.

A typical Xenomorph begins its life cycle as an egg-like creature (known as an ovomorph or simply egg) which, when detecting the presence of a potential host, opens up to release the second stage: a small arachnid-like life form (named the facehugger) which launches itself onto the host's face and impregnates it with an endoparasitoid larva. This parasite then consumes parts of the host from within and violently emerges from the host's chest cavity as a worm-like creature (grotesquely christened as the chestburster), which will quickly scurry away to find a safe place where it can molt and complete its metamorphosis into an adult Xenomorph, which happens, surprisingly enough, over the course of mere hours.

Adult Xenomorphs tend to share some common traits: a invertebrate-like body, including a protective dark exoskeleton, a long flexible tail, an elongated domed head and a toothed mouth hiding a secondary, extendable, proboscis-like inner maw. Little is known about their biology, but it is known that they eat with their inner or secondary mouths, not their outer mouths. This mouth is somewhat similar to the pharyngeal jaw of a moray eel. They also bleed an unknown and extremely corrosive fluid. This substance is dull yellow in color and often referred to as "blood", although whether it's used to transport nutrients through the body and/or serves principally as a defensive mechanism is not clear.

While the extremely corrosive fluids and tremendous resilience displayed by the creature might suggest an exotic kind of biochemistry, the fact that the Xenomorph not only feeds on Humans, but actually develops inside them, strongly suggests that its biology is carbon-based. The ability to inherit traits from its hosts also suggests that it incorporates genetic material from them, implying that the Xenomorph either has DNA, or is able to read and convert DNA into whatever means it uses to store genetic information. There is evidence that the genetic exchange is mutual (i.e. the parasite alters the host's DNA as well), given that Ellen Ripley's clones were created in an attempt to gain access to the Xenomorph Queen's genetic material, which wouldn't be possible otherwise.

Xenomorphs operate in hives made of a resin they produce, mixed up with their saliva fluids. The Queen can be generated in more than one way: from specialized royal facehuggers, or maturing from Praetorians, which in turn can mature from Drones or Warriors; by a process referred as 'molting'. Judging from the condition that any Xenomorphs can potentially 'molt' and grow into a Praetorian and then a Queen, the Xenomorph species is likely all unisexual and reproduces asexually by a process called parthenogenesis: a reproductive method practiced by many species on Earth and other planets. Alternatively, it's also possible that the aliens are either hermaphrodites or practice sequential hermaphroditism, i.e. being able to change sexes during life, as is the case with some species of fish and amphibians.

alien has a various of ways to defend or kill, their natural instinct is to hunt as they have an extremely sharp end at their long slender tail and a secondary mouth that extends like a worm like way as its teeth are razor sharp both the main teeth and the second as it could pierce skulls quickly and they are around 7 feet tall (~ 2.13 m), they are slender like creatures with razor sharp claws, they are extremely agile and quick as they can climb walls and the roof, they are very dark so they can blend in the shadows making it unpredictable of where they might be, they have a

although essentially they don't really have eyes they have a mosquito like vision that has a visor like vision as the head looked similar to a lemon, They have elongated, cylindrical skulls with eyes underneath the "visor". In the novelization of Alien, the character Ash speculates that the xenomorphs "see" by way of electrical impulse, similar to a shark's lateral line. the xenomorph can also fit in small spaces like vents, also the xenomorph has eyes but no one can see through their opaque like head or visor

although in this case the alien or xenomorph has a slender and tendril like dick
