~~~The weak... will perish.~~~– Telepathic Communication from Species 8472, Year: 2373
Species 8472 was the Borg designation for a tripedal and apparently highly xenophobic non-humanoid species whose actual name is unknown. The species originated from a dimension called fluidic space, accessible by quantum singularities. They are believed by the Borg to be the apex of biological evolution.
Species 8472 was highly xenophobic; they considered all other lifeforms to be genetically impure and inherently weak, and any alien entering fluidic space was seen as contaminating the realm. They believed the only way to purge a species of its weakness was to exterminate them, even if that meant eliminating all life on particular targeted planets. Species 8472 appeared to have appreciation for human/palman works of art, as mentioned by one of their kind in 2373.
Species 8472 was tripedal, around three meters tall, extremely muscular, and biologically unique. Their DNA was arranged in a triple helix formation, and was the most densely coded DNA ever encountered by Palman Imperium even rivalling their most complex biomonsters. Physiologically, Species 8472 was non-humanoid. They were able to withstand the vacuum of space. Their species did not require sleep. They were known to have as many as five sexes.
The species' immune system was able to destroy anything which penetrated their body systems: chemical, biological, or technological. They were impervious to normal Borg assimilation methods. Their immune system could even be used as a means of attack. If cornered, they attacked with their claws rather than with any other type of weapon, allowing Species 8472's cells to come into contact with a victim's, after which the Species 8472 cells infected every system and consumed it from the inside out. In addition, if threatened, Species 8472 were able to commit suicide by releasing a cellular toxin into their bloodstreams. They emitted a biogenic field around their bodies; this field rendered them nearly invisible to sensors and scanning techniques, making it impossible to pinpoint their exact location. This field also interfered with normal transporters.
Body size: Height app. 3 mBody color: brownish-grey to lilacBody structure: Outwardly symmetrical, visible subdivision into head - trunk - legs Head Conic basic shape with pronounced, domed forehead with two rows of peculiar depressions; a very small face containingthe two small eyes and the mouth; two characteristic deepenings at both sides of the head are probably outer ears Trunk Elongated region with typical shoulder belt, pronounced, sticking out chest armor, flat belly and very broad hip; the head is attached to the upper part with a long, wiry neck Extremities Two long arms with two joints and one hand each, connected with the shoulder belt at both sides of the trunk; the hands, attached to the wrists, are pointing down and have four long fingers each. Three legs with three joints and hoof-like feet, connected to the pelvic girdle that is much bigger than the human one.Body systems Nervous system Structure unknown; facilitates consciousness and high intelligence Circulatory system Blood circulation with lilac blood celles; motor unknown Respiratory system Structure unknown; apparently does not need oxygen, since Species 8472 is able to survive in the vacuum of outer spaceSense organs Telepathic centre used for the communication with other members of Species 8472 or other telepathic life-forms. Sense of sight created by two distant slant eyes with yellowish-green iris and black, cross-shaped pupillae The two outer ears on both sides of the head and the thin mouth in the middle of the face supposedly facilitate verbal communication
Nutrition & digestion Unknown
Reproduction Unknown; altogether, there five different sexes
Further characteristics Species 8472 has the most densely-coded known DNA, which is over a hundred times more complex than the human one.
An emitted, very strong bio-electric field makes scanning and transporting of Species 8472 impossible
Extremely resistant skin which regenerates in case of injury and even stands up to the vacuum of outer space
An extraordinary immune response destroys every biological, technological or chemical matter that penetrates the cell membrane
