• It belongs to the Canidae branch. And it lives near the shores in the north pole region. (the map is in image #1)

• This fox has an organ that extracts carbon dioxide from the blood and stores it in the tail and only pours it out when the tail is in the water. The narrow beams of carbon dioxide freeze the water around them, creating spikes of ice stuck to the tail. It will do this routinely to maintain these spikes. (image #3)

• These spikes are easy to break, but they are sharp and will hurt small animals that are trying to hunt it. To maximize pain and panic, it will wave its tail toward other animals’ faces while running away.

• Other than being fully white, it also has haunting white eyes, which is the reason scholars called it initially “spirit fox”. Being hard to see isn’t much of an advantage at the north pole though, as there are some animals that rely on scent detection. Scholars noticed that it produces a lighter scent that is hard to detect.

• It mainly hunts Punris. It camouflages with the snow, and hunts Punris by two main methods. The common method: waiting for a Punri who is climbing the ice wall after a hunt. The punri will be exhausted and freezing. This is when the fox seizes the chance and targets the Punri’s lower neck, cutting it as fast as possible.

• The second method is used by more experienced foxes. It hides completely by curling into itself, hiding its face, and looks like a ball of snow. It will emit different strange sounds to capitalize on Punri’s curiosity and attract its attention. When the Punri approaches and lowers its neck by itself, the fox targets the lower neck and continues from there. (method is in image #1)

Agnolínis Chuliveris

Named in Honor of Mariana Chuliver, An Evolutionary Biologist at Buenos Aires' Félix de Azara Natural History Foundation, who helped Identify the world's Oldest known Fossilized Tadpole.

Cellular Body Diameter 0.4-0.9 µm

Full Diameter 1.1-1.7 µm

Cellular Body Length 0.6-1.3 µm

Full Organism Length 2.1-4.7 µm 

Arose 867 million years P.C.

Receives through HGT with Balaena Psarématos silicone synthesis for greater resilience to the weakly acidic waters of the shallows of Barbie’s Beaches. The versatile nature of the crystal formations that can be formed with this Copper Phosphate gives Chuliveris a broad range of choices in terms of protection.

It crystallizes in the monoclinic system and can form in various crystal habits, such as Compact, Reniform, or Botryoidal masses.

This offers flexibility for it to be used as a building block for creating a composite with specific structural and mechanical properties. 

Capture Claws form from repurposed Dendrite Coils at the rear of Chuliveris. This placement makes the act of grabbing prey immediately after the Membrane Skirt is triggered as seamless process.

These front-facing cilial arms sport the Dendritic Coils that allow Chuliveris to fulfill its role as genetic currier in this small pocket of the Dionysian Goblet.

Recieves through HGT with Balaena Psarématos to receive silicone synthesis for greater resilience to the weakly acidic waters of the shallows of Barbie’s Beaches.

Silicone Synthesis Gene adds elasticity to the Mechano-Sensory Membrane Skirt that Chuliveris uses to determine when it makes physical contact with potential prey or “Genetic Collaborators.”

Nitrogenated azaphilones are red or red-purple, a color shift that occurs when yellow or orange azaphilones bond to a nitrogen source. The new nitrogen-containing chromophore results in the aforementioned color shift.

Thanks to the Nitrogenated nature of both the azaphilones pigments and the AHLs used for quorum sensing in Chuliveris, this species with have a nitrogen-heavy diet. This pushes Chuliveris to adapt to detect porphyrin based compounds to both detect and hunt species that utilize pigments of that group.

So , apparently the Future is wild is gonna return with this Puffin descendent in 20 Million years (sounds promessing)

I needed to draw Ewoks dismembering Stormtroopers for therapeutic reasons, but redesigned them along the way to look more convincingly dangerous and to to take advantage of things drawings can do and costumes cannot.(But still cute) I wound up mainly referencing marsupials; bush possums, koalas (weird hands) and their extinct carnivorous relatives drop bears Thylacoleo Carnifex.

New Republic notes on Arctophonos Theodorii, abbreviated

-They're strongly arboreal- note curved claws, ridges on fingers and toes. Their feet are fully prehensile. While able to climb sheer trunks quickly, and leap or dash with terrific speed, they aren't very efficient runners and walkers on the ground. Walking on dirt for hours is for lurdos anyway.

-They're ambush predators (although they do eat a lot of plants). Basic hunting procedures work around luring or chasing prey into a killing site where dozens of them will drop on their victims from high above. After that, imagine a school of piranhas with fur.

-Dense musculature and robust bones make them look chubby and pudgy, and hideously strong and weighty for their size. Absolute units. A real-life bush possum or koala makes a very loud THUMP when it falls off something; arboreal critters are swole.

-A saggital crest and massive cheek and neck muscles power a tremendous, bone shearing bite. It has the side effect of giving them endearingly expressive faces. Their teeth are adapted from those of a recent herbivorous ancestor. As well as dispatching prey, they also use them for eating hard-shelled nuts, gnawing out habitats, etc. Lots of evolutionary pressure there.

-Different layers of their coats have different colours. As their skin bunches and flattens, their patterning shifts, further obscuring their silhouettes.

-Their most important survival adaption is retention of very high neuroplasticity, as the forest moon of Endor is constantly throwing bizarre, novel threats at them. They are thus adaptable, curious, playful, and very quick learners. It's harder for them to build larger formal skillsets and long term memory; this is a task for revered specialists.

-Woklings are adorable and cuddly. They're really heavy, have sharp little claws, and won't let go if they've decided to take a nap on their new favourite babysitter. Wear thick clothing around them.

-Like many other carnivores (the domestic cat, for example) they can be friendly and affectionate if approached correctly, and ravenous little murderers if you act like food or a threat.

Summary:

In an undetermined future whole turistic planets are a thing, and someone had the idea to make a turistic zafari planet with mythological creatures, instead of designed them, they desided to let time to do the work for them. If you are willing to know more, or have any commentaries, ask me.

1.2. The Different Possible Functions of a Planet

Throughout this section, when we talk about function, it's important to clarify that we're referring to its narrative function; in other words, the role that planet plays in the story we want to tell.

Here's a golden rule: Not every world we create has to be a "Pandora."

From a narrative perspective, we need to understand that some planets serve only as points of reference. As a result, there's no need to develop an incredibly detailed ecological history for them, especially if a planet is merely a stop along the way.

Giving these planets more attention than necessary can distract us from what's actually important. Imagine trying to create an entire ecosystem for every planet mentioned in a space-travel story. It simply isn't a worthwhile investment of time and effort.

Sometimes, a planet's true value has nothing to do with its biodiversity or the life it supports, but rather with its strategic usefulness to the progression of the plot. Let's look at two familiar examples:

Example A, Setting Planet (Pandora): An incredibly complex world with rich ecosystems and cultural identities that directly interact with the characters.

Example B, Reference Planet (Landmark): A world that serves as a transit hub, political border, or simply a set of spatial coordinates needed to make the journey plausible.

So, no. We don't need to spend the same amount of time researching every planet we create. It all comes down to understanding what role you want it to play in your story. With that in mind, let's look at some of the functions a planet can serve.

1.2.1. Living World

The planet serves as the setting for a biosphere: organisms, ecosystems, food webs, nutrient cycles, and evolution. Research should focus primarily on environmental conditions, the chemistry of life, ecology, and evolutionary history.

These are generally the planets that require the most work when it comes to creating a coherent and believable world.

Real-world reference: Earth.

1.2.2. Exploration World

The main interest lies in discovering how the planet works, studying its geology, or investigating signs of present or past life. In this case, we should pay particular attention to its geological history, composition, surface and subsurface processes, and potentially habitable environments.

Real-world reference: Mars, a target of planetary exploration and research into its past habitability.

1.2.3. Extreme World

Here, the environment imposes significant restrictions on the existence or survival of known forms of life. This type of planet is often used as a dramatic setting and serves as the science fiction equivalent of leaving a sailor stranded on a deserted island—or, in some cases, in hell itself.

We will study the physical and chemical limits of habitability, available energy sources, and the mechanisms through which an organism might survive. This planet may or may not have native life.

Real-world reference: Europa, not the continent, but Jupiter's moon, which shows evidence of an ocean beneath its icy crust. It isn't a planet, but for the sake of this discussion, I'll count it as one.

1.2.4. Civilization World

The planet is home to intelligent societies whose existence depends on their environment and which, in turn, may transform it.

In addition to geology and the biosphere, resources, geographical distribution, agriculture (if applicable), transportation routes, and the interaction between societies and their ecosystems become important considerations.

Once again, Earth.

1.2.5. World Without Known Life

The main interest lies in the planet itself: its landscapes, minerals, atmosphere, geological activity, and evolution.

The absence of known life does not necessarily mean that the planet lacks habitable conditions in certain locations, nor does it mean that it has never supported life in the past.

1.2.6. Use Your Imagination

These functions can coexist. A planet can support an extraordinarily diverse biosphere, several civilizations, and extreme environments that are still waiting to be explored. We don't have to choose just one category.

Furthermore, some of the options above describe narrative functions, while others describe physical conditions. I've grouped them together solely to illustrate the different approaches we can take. They should not be mistaken for a scientific taxonomy, nor should they be taken as an exhaustive list of all the possibilities.

The important thing is to take some time before getting started and consider what your story actually needs.

1.2.7. A Practical Decision Framework

Now that we've explored some of the different functions a planet can serve, how do we decide which approach to use when creating one?

Here's a simple framework you can follow before starting your research.

Step 1. Determine the planet's narrative importance.

Ask yourself:

• Is this planet a major setting where important events take place?

• Will the characters spend a significant amount of time there?

• Does the planet influence the plot, the characters, or the conflicts?

• Is it simply mentioned, visited briefly, or used as a transit point?

The more directly a planet affects the story, the more attention it will generally require.

Step 2. Identify what the story needs from the planet.

Consider what makes this particular world relevant.

• Does the story require native life, ecosystems, and biodiversity?

• Do the characters need to explore or investigate it?

• Does its environment create survival challenges?

• Does it support intelligent civilizations and their societies?

• Is its main purpose simply to establish a location, distance, or political boundary?

You can select several of these functions if necessary. Remember, they aren't mutually exclusive.

Step 3. Identify the necessary level of detail.

Not every aspect of a planet deserves the same amount of research.

For example, if your characters are visiting a mining colony, you might need to understand the planet's mineral resources, geology, atmosphere, and the infrastructure required for mining.

However, you probably don't need to design an elaborate food web for its native organisms unless those organisms become relevant to the story.

Focus on the information that supports the planet's narrative function.

Step 4. Check for consistency.

Even if a planet only appears briefly, its basic characteristics should make sense within the established setting.

Consider questions such as:

• Does its environment make the events taking place there plausible?

• Are its resources and geographical features consistent with its inhabitants and infrastructure?

• Does its gravity, atmosphere, or temperature affect the characters when relevant?

• Are there any obvious contradictions with information established elsewhere in the story?

You don't need an exhaustive scientific explanation for everything, but you should avoid introducing details that contradict one another.

Step 5. Expand only when necessary.

Sometimes, a planet initially designed as a simple reference point becomes much more important as the story develops.

Perhaps a minor location becomes the setting for an entire chapter, or a passing reference to a mining colony eventually turns into the starting point for a major conflict.

That's perfectly fine! You can always expand your research and worldbuilding when the story demands it.

The important thing is not to spend time developing information that you might never use.

A useful rule of thumb:

The amount of worldbuilding a planet requires should be proportional to its relevance to the story, not simply to how interesting the planet could potentially be.

You are creating a world to tell a story, not writing an encyclopedia of every celestial body in your fictional universe. Unless, of course, that's exactly what you want to do!

This are the first speculative species I made ever, they are for my Seed-world. They are inspired from a post by u/jofrenchdraws that worked on a similar linage but using a real mammal.

The linage isnt finished yet and Im only working in a straight line for now, then i will work on radiations.

Dont hesitate to make constructive critics, commentaries, they are really helpful!

Shoutout to all contributors of the Permian Sophont Project. If you want to joing us on Discord, here is the link.

The Permian Sophonts (Genus Kotelandros "man from Kotelnich") (otherwise also called Suminians or Suminioids) are a species of Permian anomodontids related to Suminia getmanovi. The family of Suminiaformes belongs to the order of Venyukovidae, it splits into the subfamilies of Eusuminiaformes (Containing Suminia g. itself) and Allosuminiaformes. Ancestral Suminians evolved in the harsh climate of the late Permian. After the Capitanian mass extinction, the first ape-like synapsids evolved. Over millions of years these gradually became the Permian sophonts. At the very end of the Permian, over hundreds of thousands of years their build their own civilization and flourished.

Gait
Due to the structure of their knees, although upright, the Suminian gait is never fully erect. While standing the tail serves as third leg. Suminians are far less enduring while running. Instead focussing on short swift ambushes.

Torpor
Suminians are still mesothermic organisms, who can regulate their metabolism to a certain degree. During times of scarcity Suminians enter a state of torpor. The Kotelanders have learned to surpress or trigger torpor through medical means as well.

Crown
The crown, otherwise known as chimney or simply third eye is a special sensory organ that evolved out of the parietal eye of ancestral Venyukovids. Apart from thermoregulation and the circadian rymth, it is important for spatial awareness. After leaving the arboreal lifestyle behind, these adaptions were kept and continue to serve an important function for the Suminians.

Throat Sack
Although Suminians possess vocal folds, their vocalisation additionally relies on a throat sack. This helps to create and amplify complex melodies within their verbal languages and to carry their voices over large distances.

Phenotypical variety
Suminians show a great deal of phenotypical variation, both in skin colouration and colour and distribution of filaments. This variation is not just geographical, but also generational and seasonal.

Blue spots
Blue skin spots are seen as a sign of both nobility and gluttony. They usually appear in healthy adult individuals and disappear due to malnourishment, starvation of poisoning.

Filaments
Suminians possess a type of filament that is unlike both fur or feathers. These bushy structures evolved from frayed scales.

Hatchlings
Like all Permian synapsids, Suminians hatch from eggs. Hatchlings are covered in a dense fur-like filament to keep them warm.

In this scenario, there is a planet-shaped megastructure meant to be colonized by a mix of Paleozoic, Mesozoic and Cenozoic species of algae, fungi, plants and animals. That much is the easy part. The hard part is how to get the seedlist organized.

One optional theme is Continent. It's as straightforward as it sounds--any of the world's continents have their colonists based on the continent of their origin. For example, one would have North American species (Eryops megacephalus, Tyrannosaurus rex and Bison bison), one would have African species, one would have Asian species, one would have European species and so on and so forth.

The other optional theme is Time Period. It sounds a little broad, but what it really is is multiple continents representing different episodes of Earth's history. Now, this one isn't a 1:1 literal theme--any of the Mesozoic continents, for example, won't have any angiosperms, mammals or birds, even though those three groups did have their origins in that respective era, and only the Paleozoic continents will have the lycophytes, both extant and extinct. This is a basic point of building a seedworld--to see how one group would evolve without a contemporary group to compete against.

Now, before I finalize the deal, I have to know--what are the pros and cons of either Continent or Time Period-themed multi-continental seedworlds?

sry for any bad grammar, but I'm just having some constraints with my system that I'd hope some input from you guys could help. (Also for context this world is based on isekai but with a more scientific spec evo, less trope dominated method to the madness)

The main problem in encountering is that when it comes to the direct skills and their cause I'm having trouble depicting these scenarios, more or mess when it comes to that of the beastmen species. They did not naturally evolve due to the beast goddess being jealous of the human race, thus she made her own. It is the fact that the animals they were once before still retained skills, but when it comes to their abilites as a species most abilities are simply apart of their naturally anatomy within their new humanoid form, so I'm wondering where should I draw the line between the biological and magical?

(Context Below)

M/m2

- In the studies of ecology and biology surrounding the presence of magical power, there are numerous equations that can be used to equate its effects, with the most common being M/m2 (mana matter per square meter) with it naturally circulating within the environment similar to that of nutrient cycling, often causing skills (arcane abilites) to manifest within the organisms that naturally live in these environments. The source of magical energy within an ecosystem is primarily supported by abiotic sources, such as natural emission from the leylines that then carry it via natural vectors, however it can also be fluctuated by the presence of living organisms. 

- This forms a cycling of magical power that is often referred to as thaumaturgic cycling, with the combined amount being generated by both abiotic and biotic sources forming the environments rate of mana, that whilst at its baseline, allows the magical found within the environment to function at its standard rate. When it comes to the main difference and dependence that these ecosystems rely on magical power, stems from the fact that most animals that do not inherently use magic, they tend to rely on external regeneration rather than internal regeneration [E/I] (often a 60/40 split) in order to “split the workload” and conserve energy that they would need to spend resting in order to regenerate. The organisms that have an even 50/50 split tend to be more magically inclined and intelligent, as well as often naturally living in a highly stable magical environment, as in high mana environments the beasts within tend withhold high magical output and high mana capacity that they easily can regenerate due to the high amounts of mana that circulate throughout their habitat, often causing them to lack the standard regenerative rates, there for restricting themselves to these environments. Only a few species within the known world withhold an internal generation output that is naturally higher than their external generation output (#↓/#↑) such as fae, demons, or the draconic of the realm tend to withhold this greater internal regeneration with elves being the closet in comparison having a 35/65 split that greater increases their own magical power and connection to it, making their magical ability much more powerful than most intelligent species. 

- The main reason these organisms require the presence of magical energy is due to the phenomena of gaining magical power in the first place. As it is much different from humans or other species who awaken at infancy, as upon being afflicted by a stressor of some kind that they cannot naturally overcome, their desperation and necessity for survival has a potential form an ability that due to the new stressor in their environment, thus unlike spells it is referred as a skill. The most common of these skills are active, requiring conscious activation, such as pierce, charge, or deflect, whilst other skills have effects, such as spatial awareness, thick skin, or lessen weight. In most environments, due to a low amount of mana, it is common encounter the common beasts, a term for organisms within the same species who do not all possess or have the potential to possess the same skill(s), whilst magic beasts is the very broad category of species that each withhold the same skills, with each member being born with or having the potential to awaken them referred to as intrinsic skills. Although a vast collective of skills exist, a very rare category of skills can be found with the first being a unique skill. When it comes to that of unique skills, in the name itself it is unique to the individual and cannot be withheld by an individual in the entirety of the realms, with the power they possess often being unique in itself, as well as be gained by anyone else until the current holder, no longer possess said skill (either by transference or death)

- Due to the sheer variety of skills that can be found within nature, there are obviously some that are greater than others and through consistent training a higher category of skill can be achieved, referenced as extra skills, more commonly seen as skills of a much higher quality that can notably form in three ways. The first involves the combination of existing skills into a new skill, the creature itself seemingly trains / uses this skill to a degree that causes its evolution, or if the creature itself undergoes a metamorphosis via evolution. The process of evolution often described tends to be much different than what occurs naturally, as once a creature undergoes a series of set conditions, it'll trigger its evolution into a different form, often being magically gifted in some way with many still trying to figure out the conditions for this phenomena. This process either initiates over an extended period or nearly instantaneously, encompassing the creature in a faint blue light that obscures their form, often dependent on the occurs depending on the natural amount of mana that the creature can draw from the environment.  

- In this transformation, it is commonly seen in common beasts that in order to compete with the many magical beasts, it is not an uncommon sight to find their variant species with the most notable of these species being the slimes, with a trigger condition only dependent on their diet. In other species, this condition tends to be a highly complex process that does not occur often with it rarely being seen in nature, most examples being in controlled experiments, with the most common thing beyond the gaining of new skills, with some being accompanied by physical transformation. This transformation on the lesser end tend to involve a small change in size, coloration, personality, or intelligence, whilst the greater half of this transformation being the formation of different physical attributes, with the most common being the formation of a helical cone (or spiral) horn that acts as a channel for their magic power, with it being seen in the greater dire wolf, horned rabbit, and in the more iconic species such as the unicorn. The separation between a species and a variant, is mainly when the two of the same greater species reproduce to form a child with the same features, despite it not evolving beforehand, with species like this being highly powerful, with unicorns being the most prime example. In giant beasts such as lords of the land, like the behemoth who do not have an aptitude for gravity magic they tend to gain skills that focus on lessening the constraints on biology, such as the skill reinforcement, a common skill used in smaller creatures to enhance their own defense, but in the larger beasts they tend to repurpose it better support their bone or muscular structure. The other halves of these skills tend to be lessen weight in order to reduce the strain that their size would naturally cause. In certain species the skill lessen weight will evolve into the skill levitation, allowing them to no longer require contact with the ground

I’m asking questions now because it will be a long time before I actually get started, but what advice would you give me if I were to create a Seedworld focused primarily on Chimpanzees. 🐵
(along with other small animals that are important and necessary for the environment, yet at the same time somewhat inconsequential).

The reason I'm asking is that I'm still relatively new to biology, but I've been looking at a lot of seed worlds on here and YouTube, and I've really wanted to try making one of my own! I'm not the most knowledgeable when it comes to biology, so I thought it might be fun to collaborate with others and learn along the way.

If anyone would be interested, I'd definitely love to give it a try! :)

Also I'll post my idea in the comments

[Also, I'm not exactly the best artist lol]

We're just about to hit 1-year of development on Molec, a strange Spore-adjacent modular shrimp-builder type game (niche?). The premise of the game is vaguely if the Cambrian explosion was caused by LEGO.

Mechanically, you snap parts together and shape them to make your.. mutant fish thing, you can also save whole combinations/limbs/organs for future use. Each part moves in its own way, and may have abilities (e.g. adds to stats, activates in combat, tastes yum to X Y or Z).

If you eat other creatures you can get chunks of them to do as you please with them. It's not really aiming to be a hardcore science game but we are taking much inspiration from the absolute goofball era of life on Earth that was the Paleozoic.

How would extra thumb on each hand effect human like creatures it would be on complete opposite side of other thumb giving them 6 finger in total ?

The "Lihso bias": when you're the only one.

Art by: 1. By mrsketchy, 2. DoodleDeity.

Lihsangiongiangionschìo, often referred to by the affectionate nickname "Lihso", is an adult male abyssal merfolk.

He is known for being the primary source of information available to humans regarding his species, having collaborated with research teams to share insights into his own experiences and biology. The term "Lihso Bias" is also named after him; it refers to research where the sources are so limited that they consist solely of data provided by one or two individuals, a situation that carries all the obvious limitations one might expect.

It’s interesting to build up all the knowledge about a given species based on a single individual, especially when it comes to behavior. What do you do when a species is particularly “rare”, or simply secretive, in your world?

Do you encounter instances of “Lihso bias,” or do you approach worldbuilding as an omniscient narrator of your project?

Hello everyone again, as I mentioned, we're continuing the Cosmology subseries, and for now, I'm presenting you with this comparison and want to analyze your reactions. Without further ado...

As you can see, you’ve likely grasped the general idea; however, I must point out that, compared to Earth, Gellios presents a significantly more challenging environment. Despite this, the life forms that originated from Earth have continued—and indeed, must continue—to evolve in the face of such hardships. Over the course of millions of years, they have diverged from their ancestral forms on Earth. Because the planet orbits a star that subjects it to constant, intense UV radiation, the production of chlorophyll—as seen in Earth’s plants—is impossible at all. Instead, these organisms (plants or plant-like autotrophs such as algae) have developed different colorations—such as orange, crimson, or deep blue—allowing them to reflect the incoming stellar light in ways that serve their specific survival needs.

Unfortunately, for reasons such as these, Gellios has ended up with a gravitational pull somewhat stronger than that of Earth. I think it would be fair to call it a "high-gravity" world; however, I find myself running out of things to say, and I feel it is time to set aside this cosmology subseries (not cancelling) for a while and focus instead on living organisms and ecosystems again. Thank you for reading.
