Out into the wilds of the universe.....
The faunadex contains all the info you need to know about any fauna you might see out in the universe, including info about what they look like, where they tend to live, and how likely they are to eat all your crew members.
They just kind of shamble around, looking for food and other shambling messes. They mostly blob about horizontally, though they can straighten themselves up tallways to overcome sheer vertical faces by simply reaching up top, anchoring themselves there, and sucking all of their mass and organs upwards.
Before their eventual change, the shellage were small creatures who attached to their host, adding a small line of defense and a new point of view to their arsenal. In return for this gift, the shellage would lay its eggs into the animal. This plan of action made the host less likely to be killed by the elements and allowed the shellage to invest in a much longer lifespan than other parasites, leading to higher reproductive success rates.
Shellkers are gentle giants till provoked. For most of their lives they are immobile, stuck into the ground and waiting for unwitting prey that would pass them by. They can go several months without food in this state and move only when it seems beneficial to do so. Shellkers are scavengers by nature and can eat pretty much anything without much issue. Shellkers have been known to occasionally fish on the coasts for fish with their long tails, however it is very rare one would see a shellker out so far from their cozy desert habitat. Since shelkers cannot handle extreme cold, they have an aversion to it.
The males and females both behave very differently. The males generally lounge around sleeping all day. The males, before sleeping, will generally get twigs and leaves stuck in their fluff, so they look like large bushes. If this tactic of camouflage doesn't work, they will start to release a sort of sleeping gas. After the predator is asleep they will run away. The females roam around in search of food. Females tend to be more aggressive and willing to fight than males. Shleep do not find nests, rather, the males act as nests, keeping the babies hidden in its fluff.
On their home planet tunnelers mainly fed on cave moss and insects, but once introduced to other planets they became invasive and very large pests. Many took up residence in sewers where their powerful digestive systems allowed them to eat almost anything that fell down, including most plastics and unfortunate maintenance workers. At night they surface to hunt and forage, which while mostly harmless to sapients on Didni Wurl became dangerous indeed in other planets' cities.
If a sigma sturgeon was to be describe in two words, they would be "competitive" and "ambitious." They tend to spend most of their time exercising their strength, usually by repeatedly swimming upstream or even up waterfalls, and very rarely using said strength to their advantage when hunting.
Skidil use their tail to carry their children, keeping themselves and their children warm during cold weather, or even storing small trinkets they find in their fur. They're more often than not crepuscular and are most active at dawn or dusk, being viciously protective with their trinkets and children. They're known for adopting unattended babies of other species and raising them among their usual number of two or three children, not letting anyone take even their adopted babies.
The leader who created the smooth tiger was considered one of the worst in notail history. His "children" enforced his harsh rule. With him killed by his opposers, the smooth tiger has been changed into a more casual attitude, protecting the skies and reporting incidents to F-classes. A nocturnal species, this insect races between buildings, shining a light on curiosities. Constant goals are necessary for a smooth tiger.
In nature and behavior, the snakevine has not much to offer. Hanging from trees, its slightly sweet scent attracts would-be pollinators to their demise. Their solitary nature means they do not need to hunt much. They group loosely, not for any social structure but for lack of care, only leaving when prey numbers drastically drop due to overcrowding.
Space bears are a genetically engineered species originally meant for circus performances, that has somehow escaped and survived in the wild. This makes them very docile despite being predators, space bears simply fly around space, minding their own business and hunting smaller space fauna. The space bear's biggest obstacle between itself and survival is its convoluted mating ritual. The male space bear will fly down to a planet, leaving pheromones and to try and lure a female space bear to the planet, and staying there until its cubs are born. They become extremely aggressive during this phase, and because space bears are rare and space itself is huge, it may be decades until another space bear finds them, making space bears a nuisance when they decide to nest near civilization.
It acts mostly like a llama, except for the fact that it goes wherever it wants, does whatever it wants, ignores any and all attempts too, actually that's still just a normal llama, it spits at people and everything. The main distinction between normal llamas and space llamas is that they're very solitary, or at least, no more than one has been at a time.
Space tuna are skittish detritivores that mostly try to hide away from other space creatures for fear of being eaten. They can live entirely off solar rays, though they mature much faster if they are able to eat dead space fauna. Space tuna rely on the brain power of other tuna and can only function and survive when there are three other space tuna nearby. Groups of less than four tuna die off and any tuna in a group beyond the first four will die off and get eaten.
As stated in the physical description section of this fauna's article the space peanut bush is able to be summarized as unassuming despite their nature of being an ambush predator and ambulatory plant. Colloquially it's docile behavior is phrased as "shaky bush likes dancing" and to the casual observer there is nothing worth mentioning outside of this statement.
Spikmews like to get attention of others no matter if it's one of their own or another species. They enjoy either tapping someone softly with one of their front claws or mewing repeatedly. If the person shows the slightest sign of annoyance or aggression while doing this they will flee instantly.
A squarmid is a capture creature with a simple 'lesson', given mainly to J-class children. Anyone who has watched a squarmid can summarise its behaviour with a simple phrase - squarmids are thieves. Being extremely curious, squarmids tend to pick up whatever they find interesting, or whatever their owner seems to be interested in keeping, and store it in their tail scales. Due to this, it is common for a squarmid to steal something from its owner that was important to the owner. In fact, this is part of the point.
Squibbins are quite curious yet cautious critters. They will follow unfamiliar creatures at a distance with their groups. If said creature does not pose any threat to them squibbins will come closer to investigate and sniff said unknown animal. Usually after sniffing the squibbins will lose interest and leave whatever it was alone unless it is small enough for the squibbin to eat.
Considering that squigets were modified with the aim of being I-class capture creatures, they can be difficult for the more inexperienced pet owners. Being prone to hiding and hoarding their owners' belongings, and additionally being difficult to befriend, squigets certainly aren't easy pets. Though, this hardly seems to deter those who want one.
In their cute form, stakils will usually be found either sleeping or hiding from predators. They will sometimes approach their prey in this form in order to get as close as possible before they transform. While they aren't as strong as other predators, they are considerably more intelligent. They are notorious for ambushing their prey, and occasionally lead them into a corner, so they cannot flee. They will sometimes leave infants or children of their prey alive, so they can fatten up and have more meat on them when the stakil does kill them.
Once a pack of stellar drakes has consumed a star, they disperse in random directions to seek their next meal. This can take them very long periods of time, and wandering stellars have been known to descend upon herds of solar deer to satiate themselves until reaching their next star.
The tailmic is a capture creature for G-classes and U-classes. It is by far the most common capture creature, as it freely roams many, if not all, notail settlements. Notails seem to have a kinship, or at least a strange and extreme tolerance, with tailmics and will do nothing as they casually come over and eat food, sometimes even out of the hands of a notail. If a notail is ever annoyed by a tailmic they gently place their hands on their heads and push them to let them know they don't want to be bothered. This action rarely happens though, instead, tailmics live inside the houses of notails, wander their stores, even crawl around their labs undeterred by anyone.
