Fauna 001: a flattened and transparent blue arrow. Its opposite end has never been observed. It extends slowly and cuts matter, which dissolves into its surface and evidently sustains it. No two 001 instances have been observed at the same precise depth, or observed to ever adjust their depth.

Fauna 002: a column of irregular, polygonal segments with a rough metallic texture, each roughly three meters across. Segments range from six to 27 sided shapes and rotate in alternating directions. Rotation periodically accelerates, generating extreme heat between segments. This heat attracts Fauna 003 (see below), which ignite and carbonize as they land on 002. Carbonized 003 are not consumed by 002 through any observable means, but a corresponding segment develops another facet per "kill." On developing 28 facets, a segment will break apart into three new segments with a minimum of six sides, increasing the entity's length. The shortest observed specimen possessed eight segments. The longest possessed 81,455.

Fauna 003: clear, flimsy, "heart" shaped organisms lined with angular veins, pale green at rest with the capacity to bioluminesce across the visible spectrum. 003 "flap" through the void by folding and unfolding lengthwise. 003 are attracted to heat, and each individual splits into new 003 when exposed to heat from any source other than Fauna 002. Testing indicates that this is not connected to temperature level; 002's maximum heat output is recorded at 260c, while 003 reproduction has been induced by temperatures exceeding 3500c.

Fauna 004: invisible, shape currently unknown. Presence is marked by a metallic buzzing sound. 004 consumes metals by unknown means, easily tearing away small pieces which remain visible in what is assumed to be its interior, dissolving over the course of several hours. 004 evidently identifies metal by a combination of texture and color.

INCIDENT F004-1: a chrome-plated plastic object was offered to an 004. Specimen "ingested" the object, then violently ejected it toward the survey vessel. It emitted a previously undocumented sound as it fled, and subsequently no instances of 004 have since attempted to feed on survey equipment or experimental offerings. It is hypothesized that instances of 004 either communicate with one another over food sources or all observed instances were of the same individual.

Fauna 005: a multicolored disk of light, varying in size. Can "unravel" into a spiraling filament and "tighten" again with enough speed and force to slice apart solid objects as it reconfigures back into a disk. Prefers to "attack" objects that emit light. Oboe music causes 005 to turn uniformly purple and discontinue all aggressive behavior.

Fauna 006: a flexible seven pointed star-like shape, blacker than the surrounding void. Its surface is uniformly covered in sharp growths that can "drill" into solid matter, consuming material in the process. Any light source filtered through blue glass will cause 006 to "scream" and collapse into a small spherical configuration, which plummets straight downward. This phenomenon was the first recorded indication that Antispace entities orient themselves around a consistent "up" and "down," though no source of gravity has been detected.

Fauna 007: identifiable by dense, continuous ultrasonic soundwaves confined strictly within a drifting ovoid area with a wider, flattened "tail." Dubbed the "soundwhale" by survey crew. No other material or energy components have yet been identified, and soundwaves are found to bounce indefinitely off 007's intangible walls without a loss of energy. Most Antispace material within 007 rapidly evaporates in a pattern physically consistent with sonic bombardment, regardless of actual composition. The effect is significantly slower on most foreign materials, beginning as an uncomfortable "tickle" in human subjects for up to eight hours of continuous exposure before any observable tissue damage. Smaller 007 have been detected following larger specimens, and are incapable of "feeding" on their own. Evaporated matter is instead passed to these smaller specimens through a cone-shaped area that can extend and retract from the "underside" of the "adult's" borders.

INCIDENT F007-1: 007 soundwaves were determined to degrade all tested materials other than copper. A copper canister was experimentally "dipped" into a passing 007 via drone, and the canister sealed before removal from the "soundwhale's" interior. Canister continued vibrating for 47 hours with increasing intensity until the "trapped" soundwave ruptured its container, penetrating three walls and one researcher at what was subsequently found to be the speed of light at observable minimum. Analysis of the damage pattern determined its trajectory to be a mathematically absolute straight line towards the 007 it originated from, at the time more than 4000km distant from the research vessel.

Fauna 008: not directly observed. Survey crew observed various other fauna in a state of degradation, marked by fractalized patterns of "decay," loss of coloration and impaired movement. Subjects making visual contact with these patterns experience a "realization" that the entity responsible is a loosely connected network of particles existing 0.23 seconds in the future. It is impossible to ascertain the veracity of this information or the precise means by which it is communicated.

Fauna 009: a rubbery blue-grey object likened to a stingray, but invisible and evidently immaterial on only its ventral surface. Matter passing into this "empty" side of the being is lost as 009 continues its high speed flight through the void, and is observed to grow in mass exactly equal to the mass of this "ingested" material. Materials retrieved by tether from 009 are found to be coated in a substance almost identical in chemical composition and consistency to petroleum jelly. Analysis indicates that 009 decrease in size in exact proportion to all removed materials, including the volume of this gel.

Fauna 010: identifiable by nothing other than an emotional state experienced by human subjects on "contact" with 010, neither pleasant nor distressing but reportedly incomparable to any familiar emotion. Strategic placement of personnel in 008's path has determined its shape to be a horizontal, flattened crescent twelve meters in width, with a large sphere dominating its center between two smaller spheres. All other Fauna are observed attempting to flee from 010 if capable of locomotion. Fauna that cannot evade 010 are observed to vanish instantly on contact with the absolute borders of its spheres. Analysis concludes "prey" are destroyed by tremendous gravitational force. It is not known why materials foreign to Antispace are unaffected.

Fauna 011: a collection of up to five long, rippling red "curtains" radiating out from a subatomic central point, likened to a spatial singularity but lacking a gravitational field. These "curtains" or "arms" extend up to sixteen miles in length and widen to roughly a mile in maximum width before ending abruptly. This material wraps around nearly any matter it comes into contact with and slowly ferries it to the central singularity. Instantaneously, these "consumed" objects are ejected as innumerable perfect spheres of red corundum ("ruby"). Several billion of these gemstone waste products typically drift around the center of 011 in a dense cloud.

Fauna 012: the most "animaloid" fauna yet observed. A cross shaped configuration of white, flexible, segmented tubes ranging from six centimeters to nine meters across. 012 walks in a crablike manner on Fauna 011's appendages, remaining at least half a mile distant from all others of its kind. Seemingly undetected by 011, it is capable of consuming matter through any of its tube tips and will attempt to feed on captured material before 011 can consume it. Instances have also been observed absorbing portions of 011 material, and deliberately "hitching rides" on fragments they have severed from the main mass. These roaming instances have been observed up to 1200km from the nearest 011, and maneuvering their fragment into smaller entities such as 003 in a behavior resembling "tool use." All observed instances of 012 "stand up" on a single tube and "wave" their remaining three when probes come within .5km, emitting a series of "saxophone-like" cries until the probe has passed. This behavior has not yet been displayed towards other entities on record.

Fauna 013: an amoeboid mass of ochre-colored, doughy material with sparse clusters of thin, waving pseudopoda. 013 varies in shape with a minimum diameter of 60 meters and a maximum outstretched width of 404 meters. Any object approaching within 100 meters is impaled by a pseudopodal "lance" that extends to precisely 100.05 meters in 1/100th of a second. Formation of this defensive appendage begins as a single conical swelling in response to any object within 700 meters. 013 is noted to move slowly away from these objects, occasionally firing the lance at less than half maximum length, a behavior interpreted as a "warning."

Fauna 014: thus far identical in every observable aspect to a common adult housecat, female, black furred and missing its left rear leg due to an unknown past injury. Observed sleeping comfortably atop Fauna 013, awakening every four to six hours to clean itself, stretch, and return to sleep. Fauna 014 emits a continuous sound indistinguishable from the purring of a normal cat whenever conscious. Fauna 013 and 014 have been observed 24 reported times over a period of 72 years with no observable changes in behavior or apparent health. It is not known what sustains the biological functions of Fauna 014.

INCIDENT F014-1: crew held a position outside the range of 013's defense mechanisms and attempted to attract 014's interest with a number of audio recordings. These included a range of feline calls, food bags and food cans being opened, running water, birdsong, cat toys and human speech samples. 014 ignored all stimuli but the human voice, which it reacted to by fleeing to the opposite side of 013. 013 was observed to begin actively approaching the survey crew and readying a count of at least 83 "lances." All further interference with Fauna 013-014 is prohibited.

Fauna 015: object resembling two curved, rocky cones or "horns" intersecting with one another in a cross shaped configuration. Pale blue, luminous surface is covered in circular pits that emit a continuous ringing sound.

INCIDENT F015-1: object began to follow survey crew 023, during which an increasing number of crew began to emit the same sound and attempted to leave the safety of the exploration vessel. As soon as any crew exited the vessel and exposed themselves to the void, 015 ceased all activity, approached the crew slowly, then fled backwards with extreme speed. All affected crew regained their autonomy, but have suffered long term psychological effects similar to extreme separation anxiety. All afflicted personnel were removed from survey duty.

INCIDENT F015-2: six former members of crew 023 breached protocols and boarded exploration vessel 44N on an unauthorized launch, severing all communication channels. It is presumed these personnel left in search of the same 015 from their previous encounter. A following survey mission retrieved several heavily damaged pieces of 44N's hull within 015's known territory.

Fauna 016: a point of bright, white light less than 1mm across, which moves along solid surfaces similarly to the light of a laser pointer. 016 moves at a rate of only 1/2 inch per second, but appears to be attracted to the sound of a living human heartbeat. No other organism, material, or even artificial replication of the appropriate sound has affected 016's trajectory. Contact with human skin causes an exponential breakdown of tissues until the subject is completely liquefied over the course of 72 hours, after which two new instances of 016 emerge from the remains. It is thus far impossible to contain 016 in any known material.

INCIDENT F016-1: two instances of 016 are believed to have been brought back unintentionally with the return of survey crew 034. The first instance was successfully returned to Antispace while consuming a host.

ADDENDUM F016A: further experimentation with Fauna 016 has found that each subsequent generation of "offspring" exhibit a 2% increase in speed.

ADDENDUM F015B: field observation has determined that 016 can detect the nearest human "prey" within 643km.
