Fauna includes all lifeforms capable of free movement.

Summary[ | ]

In No Man's Sky, "fauna" is the "umbrella category" which includes all lifeforms capable of moving around the environment on their own. Although the strictest definition could be used to describe humanoid life (Gek, Korvax, Vy'keen, and possibly Travellers), "fauna" is not usually used to describe humanoids. The category "fauna" is commonly referred to as "animals," which may or may not be technically correct. In Earth biology, "animal" refers to Animalia, which the majority of No Man's Sky fauna do indeed seem to resemble.

For records on the largest and smallest fauna in the game, see Fauna Hall of Fame.

Location[ | ]

Their nearby location can be identified by red dots (new species) and green pawprints (already scanned) through the Analysis Visor. Most species also vocalise (with roars, "yells," squeals, etc.). Fauna can be found anywhere on a planet, including in the air, although some planets will have no fauna or areas (ground, underground, underwater or aerial) with no fauna. Some species are only found in a certain hemisphere of a planet. In the given case, after scanning a fauna, the hemisphere is displayed in the planet's fauna list on the right side of discovery menu Screen, below the creature's name: next to rarity, ecosystem and activity information.

Upon landing on a new planet or checking a planet in the discovery menu (pause menu), the density of fauna (or lack of fauna) on a planet can be checked. However, some animals described as "rare" will sometime overrun the player's field of view while an "uncommon" animal will stay nowhere to be found for an extended period of time. Experience has shown that underground creatures in particular are sometimes harder to detect. In this case, re-exploration at a later date, or a reload, is recommended. Furthermore, it should be noted that the Prionace genus is generally sighted almost exclusively in the deep waters of a planet's ocean(s).

Gender[ | ]

The gender of a species is displayed by the analysis visor after scanning, as well as in the discovery menu. In the discovery menu, however, only one gender is listed after scanning - even if another one should exist. For this reason, it is recommended to observe several representatives of a species through the analysis visor for complete documentation.

A species can have a single form of appearance, or two different forms - so called models. The gender does not necessarily go along with the appearance form, so sometimes discoverers will be surprised.

Originally, 17 genders were discovered in No Man's Sky. With updates and additional exploration, more genders have been documented. Below is a list of all known genders to date. The possiblemeanings are taken from the last accessible archive entry dated October 6, 2022.

01 Male The masculine part of reproduction.
02 Female The feminine part of reproduction.
03 Exotic This species may not fit into any category found on Earth gender wise.
04 Unknown The gender of this animal isn't known.
05 Indeterminate It is impossible to say what genders exist in this species.
06 Asymmetric This may be the same as "hermaphroditic/monoecious" in Earth biology, organisms that are of the same sex and can perform either or both sides of the mating act, like most snails.
07 Non-uniform This species may have multiple gender layouts across its entire species, much like several lizard species on Earth.
08 Symmetric Perhaps similar to asexual reproduction in Earth biology.

Gender Exploration Experiences[ | ]

Terrestrial (ground and underground) fauna species usually have two genders. Contrary to the original perception (concerning the first updates), for quite some time now, two genders have also been detected in aquatic and flying fauna.

Differences in the gender of a species can usually be identified by their appearance. However, experience has shown that although, for example, a species had two different appearances, one of these appearances could be documented as having two different genders. Here is a documented example: E. Helodaerera.

Furthermore, it was observed that when a celestial body was later re-explored and a particular fauna was rescanned, the gender and/or scientific name of the fauna was displayed differently in the Analysis Visor scan than in the original, very first scan - although the original scientific name and gender were still listed in the Discovery Menu screen. It seems that mainly species of the genus Protosphaeridae, Prionterrae and Prototerrae are affected. Here are two documented examples: A. Bikokus, E. Bearsolveum

The article on Divergent Species discusses this extraordinary phenomenon.

Age[ | ]

Fauna age in 10 different ways. Below is a list of all age categories, and some possible meanings.

  • Immature: Infant, Young, Juvenile
  • Mature: Adult, Mature, Elderly
  • Other: Indeterminate (Age or aging pattern unknown), Constant (Possibly means they never age), Fluctuating (May be able to change their "age" based on their lifecycle, like some jellyfish), Perpetual (Possibly "continually aging, never dying," effectively "immortal.")

Diets[ | ]

Fauna can follow 9 dietary patterns, divided into 3 subgroups.

  • Carnivore: Carnivore, Meat-Eater
  • Herbivore: Vegetation, Absorbed Nutrients, Herbivore, Grazing Creature
  • Omnivore: Scavenger, Insect-eater
  • Pica: fauna with unusual diet appetite for Oxide elements, rocks or soil, etc.

Some of these categories may seem redundant - for example, "Carnivore" and "Meat-eater," or "Herbivore" and "Grazing Creature." However, there could be slight distinctions between each option which are thus far unclarified.

Most of the documented "diets" are listed on the Creatures - Discovery Aspects page - with additional indication of the corresponding text passage as found in the Creatures - Discovery Menu.

The following table shows the fauna diet habits documented so far. The rough classification was made, concerning usual fauna, according to the ecosystem in which the creatures occur. But unusual fauna is also listed here.

Observable behaviour Impact[ | ]

Carnivorous and omnivorous species will be hostile to the player, and sometimes other fauna.

Herbivores will display grazing animations, perhaps most noticeable with Rangifae (diplos) which lower their heads down to the ground with their long necks.

Carnivore[ | ]

As a completely speculative example of possible distinctions, "Carnivore" may be the same as "obligate carnivore" in Earth biology, animals that strictly eat meat and nothing else. While "Meat-eater" may be the same as "facultative carnivore," animals that eat mostly meat, but may occasionally eat plants as well (or in the case of NMS, other...elements). "Herbivore" could apply to any animal which eats plants, while "Grazing Creature" might specifically requires grazing behaviour.

Bait[ | ]

After scanning a species you are provided with information regarding "bait" which is used to tame creatures and take advantage of additional abilities.

Some baits are just for "pacification" of creatures and will make them friendly, similar to how you could feed them random amounts of isotopes in previous updates. This is now done with "nutrient pellets" as the lowest "tier" bait.

Higher tier baits may enable to ability to ride medium-large creatures. (This does include flying creatures of medium/large size) This same tier of bait allows the ability of harvesting/milking creatures.

Height & Weight[ | ]

The overall size of a species is determined by two factors: its height (or length) and its weight. As weight has no direct effect on the game and seems to give unusual values at times (such as butterflies being extremely dense), height is usually considered the more important characteristic.

Height is a measurement of how tall a species is. Different genera have different size limits, primarily governed by their ecosystem (for example, there are no flying or aquatic fauna above 4m, and certainly none above 8m). So far, no creatures above 8.43m have been confirmed. Eight (8) meters can be considered the "soft limit," as it seems no species will grow much taller than that. The smallest known species is 0.07m. Note that with the NEXT release, the hundredths digit was dropped, providing a size range of 8.4m - 0.1m. As a result, the largest and smallest known species from Atlas Rises will never officially be exceeded.

Weight is a measurement of how heavy a species is. It's difficult to say how it's determined, as the smallest species found so far is as heavy as some species ~14 times their size.

Megafauna[ | ]

NusokyviussemPNG

Megafauna.

At a certain size, a species will shake the ground with its footsteps (with the exception of hovering fauna, like winged Grunts or hovering Beetles). Such species are referred to as megafauna. Only certain fauna can become megafauna - aquatic species, birds, and butterflies have a smaller "maximum size" than other types of fauna, and cannot grow to a true "megafauna size."

"Megafauna" is not a term used by the game, but the term is frequently used by the playerbase.

Ecosystems[ | ]

Fauna can be found in four (technically five) ecosystems. The ecosystem of a given species is displayed in the planet's faunal list on the right side of the Creatures - Discovery Menu screen, below the creature's name: next to rarity, activity and possibly hemisphere information.

  • Ground (Terrestrial & Hovering) - While you may think Hovering species would be in the Air ecosystem, they're actually bound to the ground.
  • Air (Flying) - Wraiths / flying snake-like species, and flying winged species both large and small.
  • Water (Aquatic) - Fish, predatory fish, jellyfish, segmented aquatic worms, aquatic mammals, shrimp-like species, etc.
  • Caves (Subterranean) - Subterranean species are strictly blobs, arachnid/crustacean-like species, rodent-like species, and Prototerrae.
  • Sentinels - This is the "only technically an ecosystem." Sentinels are also the only entities allowed to freely cross between ecosystems, although actual fauna may cross between them occasionally or by accident.

Activity Periods: Nocturnal / Diurnal Behaviour[ | ]

The day and night cycle affects the spawning of fauna. Different species will behave differently based on the time of day.

Nocturnal species are active strictly at night. Diurnal is the opposite, with these species only being found during the day. Many species are mostly nocturnal or mostly diurnal, being more active during a certain time but still present during the rest of the day. Creatures won't suddenly disappear if time cycles out of their period of activity, but they will start/stop spawning new ones or increase/decrease their spawning frequency.

The following information is based on pre-Foundation datamining, but it appears to still be accurate. So far, it appears that no updates have significantly changed how fauna spawning and behaviour work, aside from increasing the maximum size of fauna.

  • Some flying fauna will be less active or entirely inactive at night. There are no nocturnal or mostly-nocturnal flying fauna.
  • Butterflies on any planet are strictly diurnal.
  • On most planets, predators are more active at night. They can be up to 8 times more active, or even entirely nocturnal.
  • The opposite is true on a smaller number planets - like "dinosaur planets." Certain predatory species will be four times more active during the day, or strictly diurnal.
  • A very small number of passive species are strictly nocturnal; a larger number are strictly diurnal.
  • Many passive species are more active during the day than during the night, but still active at night. Some are unaffected by the time of day.
  • Aquatic & subterranean fauna are consistently active during all times of day and night.

Temperament: Predatory / Defensive Behaviours[ | ]

Fauna can display both predatory and defensive behaviours.

Defensive behaviour may occur in the form of self-defense, or in the form of defending their young. These are the only two known patterns of defensive behaviour. It appears fauna only defend themselves against the player, not against predators.

Predatory behaviour can be directed at the player or other fauna. There are three main types of predators, and two other categories of fauna behaviour.

  1. Predator - A standard predator, this will attack any species classified as "prey," as well as the player.
  2. Player Predator - These predators will only attack the player, not other fauna. Player Predators are usually small.
  3. Aquatic Predators / Sharks - These predators do not appear to attack other aquatic life, but will attack the player.
  4. Prey - Prey species are ordinarily non-hostile, but will defend themselves if attacked by the player. Prey species will also defend their young, attacking the player if the player harms a young member of the species.
  5. Passive - Passive species are non-hostile species that will only flee when attacked; they will not defend themselves under any circumstances.

Temperament List[ | ]

Fauna also display behaviour ("Temperament" prior to NEXT), listed in the Discovery Menu. There are 37 behaviours divided into 5 subcategories. At this time, it's unclear if specific behaviours within a category have any effect on the behaviour of the fauna, or if all subcategories behave essentially the same.

"Generic" behaviours most likely apply to fauna which display neither predatory nor defensive behaviour, such as Ictaloris (fish) or Oxyacta (wraiths).

  • Generic: Unintelligent, Migratory, Hibernator, Distinctive, Active, Erratic, Unpredictable, Bold, Sedate
  • Passive: Ambulatory, Amenable, Calm, Docile, Far-sighted, Passive, Submissive, Unconcerned, Wise
  • Prey: Anxious, Cautious, Defensive, Fearful, Prey, Shy, Skittish, Timid
  • Player Predator: Aggressive, Cruel, Dangerous, Hostile, Reckless, Vicious, Violent,
  • Predator: Hunting, Predator, Stalking, Unpredictable, Volatile

As Predators and Player Predators have distinct temperaments, this list can be used to determined whether or not a specific species will attack other fauna or only the player.

Divisions & Scientific Name[ | ]

The broad category of fauna is further divided into three smaller categories based on Earth taxonomy. From most to least broad, these categories are Family, Genus,, and Species. The entire game has a total of 23 genera, while an individual family or species never appears on more than one planet.

Using the information below the player can more accurately name their planet's animals.

Family[ | ]

(Note: In Earth biology, "Family" is a more broad category than "Genus.")

Families in No Man's Sky are much more broad than they are in Earth biology, but they do share some characteristics. For example, on the planet Galactic Hub Summer Embassy, all Oxyacta species belong to the Idiumptu family, and two aquatic species belong to the Kaspers family.

Unlike "Genus" and "Species," "Family" is not an actual term used by the game code, but nonetheless a useful term to describe the identical name parts between some species.

The family of a species can be identified by the second half of its scientific name. For example, the Rigatori Niplatea species would belong to the Niplatea family.

Genus[ | ]

Genus (pl. genera) is a characteristic of fauna in No Man's Sky. Unlike the procedurally-generated Family characteristic, the game's code references the Genus characteristic in determining where a species spawns. For example, the game will always spawn one butterfly species (genus Rhopalocera) and two predatory T-Rex species (genus Tyranocae) on "prehistoric planets." A genus is also restricted to one (or in some cases two) ecosystems, ie, "Aquatic" or "Subterranean."

Species & Family[ | ]

These groups appear to be isolated to one planet - a species or family will never appear on two different planets. The name for each creature contains two procedurally-generated parts: a unique Species name (the first half) and a Family name (the second half).

Families in No Man's Sky are much more broad than they are in Earth biology, but they do share some characteristics. For example, one family may all be water dwellers, and others seem to all be four-legged terrestrial creatures. Unlike "Genus" and "Species," "Family" is not an actual term used by the game code, but nonetheless a useful term to describe the identical name parts between some species.

Examples of Families and Common Traits[ | ]

  • Bahalbus - Passive, quadrupedal terrestrial species.
  • Ouisque - Beaked, flying bird-like species.
  • Sitalie - Fish-like species with stripes / spots.
  • Ubsans - Passive, quadrupedal terrestrial species.

Species & Gender[ | ]

Besides gender, species is the most specific category of fauna. Each species has one or two models of appearance. Aquatic and flying animals usually have one appearance model, while most terrestrial animals usually have two models. Here is an example of a flying fauna with two appearance models: G. Telealneum

For some time now, the scans of the Analysis Visor have often shown two different genders and sizes of a species, regardless of the genus - although originally aquatic and flying fauna were probably excluded.

An appearance model is not necessarily associated with a particular gender. There are examples of two different models of a species, with one appearance model spotted in two different genders, f.e.: E. Helodaerera.

Using Taxonomy[ | ]

Acocuppl Hobell

Acocuppl Hobell.

Using the information on family, genus, and species above, one can classify the Rigatori Nipatea as Niplatea (family), Rangifae (genus), and finally rigatori (species). The specific species, when being talked about, would then be simply referred to as "R. rigatori." This is called the scientific name, or the binomial nomenclature.

To help further explain this process, here are a few more examples of classifying a species.

  • Evectagu Saviso: Saviso (family), Tetraceris (genus), evectagu (species). T. evectagu.
  • Acocuppl Hobell: Hobell (family), Icaloris (genus), acocuppl (species). I. acocuppl.
  • Befecus Nidustares: Nidustares (family), Ungulatis (genus), befecus (species). U. befecus.

Divergent Species[ | ]

Divergent Species are a type of species in No Man's Sky which, when scanned, do not count towards the Total Number of Species Discovered on the planet. These creatures are believed to be a glitch of the original scanned fauna, creating a different version of the original species. They will have the same statistics and appearance as the species it originated from, only differing in preferred bait and species name, although opposing genders displayed in the Discoveries tab may give the illusion of one having a different height, weight, or appearance. In rare circumstances, one may have a slightly different coloration or head ornamentation. It is currently unknown what triggers one to appear, although exploring in multiplayer groups seems to increase their frequency.

Planet Diversity[ | ]

The number of species found on a given planet will vary, with the average being 7-8 different types. Based on current records, the maximum species for any planet (based on ecosystem) are 8 ground, 3 underground, 5 underwater, and 5 flying.

Planets with 17 or more species are rare, as they have reached at least 80% of the maximum. The following is a Top-10 list.
