Xenobiology - Tumblr Posts

Want to work on a good expression sheet for styraphants but got distracted drawing flustered flirting. Also decided they talk through rumbling air within an inflatable sack in their chest! It's also how they blush because how cute.

I carried 2 alien species by AI.

👽🛸

Is a random drawing of these intelligent alien species I just created.

And also, maybe I will draw more of these guys.

My new headcanon is that trolls aren’t some weird pseudo-mammalian half-insect hybrid species, they’re mimics. Like bee flies and that one caterpillar that looks like a snake. Seeing as they’re a conquering race, and have apparently had access to space flight since FOREVER, probs they originated on a planet where a semi-humanoid mammalian species was the dominant lifeform, and trolls were outnumbered. Gradually, over millions of years, they adapted themselves to look sort of like that species, in order to keep from being eaten or killed, and eventually grew powerful/technologically advanced enough to eradicate said semi-humanoid species and become the dominant lifeforms themselves.

I think that explains things like trolls having secondary sex characteristics despite being able to reproduce regardless of sex, and having notable gendered expressions and mannerisms, also despite no apparent difference in reproductive abilities.

Probs someone else came up with this first but w/e.

The is a tardigrade, aka water bear. And this little thing can survive the most extreme conditions — boiling heat, freezing temperatures, even the vacuum of space. But what’s so special about this little guy?

Well this microorganism can survive from just above absolute zero, to well above the heat of boiling water. Pressures greater than the deepest point of the ocean by 600%. They can live without food or water for 10 years.

The European Space Agency even sent some tardigrade up to space, under an experiment called TARDIS — tardigrades in space. Where the results were stunning. Many of them survived the solar radiation, vacuum conditions, freezing temperature, dehydration and other extreme conditions. And.. It didn’t even affect their reproductive behaviors.

So what? It can live in extreme conditions, why does that matter?

Well the tardigrade have showed us that where life can exist, it will exist. Which makes us realize, maybe life doesn’t need to exist under all the conditions we once believed. If tardigrades can exist under these conditions, what about extraterrestrials?

Knowing about the tardigrade, there are so many more possibilities of finding extraterrestrial life. Now its up to time, and the work of our diligent scientists to show us where it exists — I know its hiding out there somewhere!

Spy's Spec-Bio Essentials

I honestly didn't mean to write a full-on essay, but I couldn't help myself -I love specbio, and the recent revival of interest in it makes me very happy. If you wanna just get right to the meat: normal links are highlighted blue, YouTube links are highlighted red.

Speculative biology has its roots as far back as Pliny the Elder and his Natural History, though most consider H.G. Wells to be the true grandfather of the genre with works such as War of the Worlds, The Time Machine, and Man of the Year Million. However, any speculative biologist worth their salt credits Dougal Dixon as the father of specbio as we know it today –especially since he is the man who coined the term! Dixon's books After Man, Man After Man, and The New Dinosaurs are considered the foundational works of modern specbio. So too is Wayne Barlowe's book Expedition.

While the original printings of these books are very expensive to acquire, After Man recently received a Kindle version, and Expedition has a very good documentary adaptation available in totality on YouTube. Another important work of early speculative biology was the Discovery Channel limited series The Future Is Wild, a documentary show exploring the possible futures of life on Earth in several million years' time.

With the rise of the internet, people interested in speculative biology –those few and far between– could share their thoughts and amateur works with each other. Online specbio hit its first height around the mid-aughts to early tens, featuring many notable works that were very influential to me personally when I joined the scene circa 2014. Unfortunately, right around when I joined there was a notable "mass extinction" –many of the more active and prominent figures of the specbio community left the web behind for various reasons, and thus the golden age ended.

In recent years, partially thanks to certain YouTube video essays on the classic projects, interest in speculative biology seems to have increased dramatically! I've taken to calling the current era the "specbio renaissance," and it makes me so happy to see new, younger people interested in this unique facet of creativity. In light of this I've created this master post of my personal recommendations of essential specbio works for new "speccers" to enjoy!

The specbio community has congregated on forums for decades. I personally joined the community via DeviantArt right around when the old ZetaBoards forum underwent a massive host shift and never participated on the forum all that much, but fortunately the old Speculative Evolution Forum is still up and still active!

For those who'd prefer a simpler way to keep up with current events in the specbio community, Astrovitae is a free e-magazine dedicated to contemporary spec. A product of the recent specbio renaissance, Astrovitae only has a handful of issues thus far but is already becoming a staple publication in the field.

I made this post to provide what I think is key information and important resources, but the SpecBio Wiki is a far more thorough companion to your journey into the world of speculative biology. As always, though: beware ye old Wiki Rabbit Hole!

Biblaridion's Alien Biospheres video series is an excellent entry point for anyone looking to learn the basics of specbio. It's a demo xenobiology project, with a heavy focus on the scientific concepts used in building up the world and its ecology.

Curious Archive's Alien Worlds video series is an excellent collection of bite-size examinations of various specbio projects, including several on this list!

Nemo Ramjet (C. M. Kösemen)'s Life on Snaiad is universally considered a classic work of speculative biology, started in the early days of the golden age of internet specbio. Snaiad is an alien planet, in its early days of human habitation, filled with strange lifeforms bearing two "heads."

Kösemen's other well-known classic work is Alltomorrows, a short ebook exploring hundreds of millions of years' worth of possible human evolution. Readers, be advised: this work contains extensive body horror and discussion of human extinction, both circumstantial and deliberate.

Sagan IV, originally created by Hydromancerx, is one of the oldest and most extensive specbio projects. Started as a simple artistic exercise on a forum in 2006, Sagan IV has evolved into a large, highly collaborative vision of an alien world inspired by the works of Carl Sagan. It is still ongoing today, and you can participate in their regular contests and activities!

Gert van Dijk's Furaha is another of the well-known classic specbio projects, and one of the few from the golden age that is still fully active. Furaha itself is an alien world orbiting Nu Phoenicis which harbors a fascinating native biosphere, built upon carefully-researched biomechanics. The site itself is laid out much like an encyclopedia, and the accompanying blog is a treasure trove of specbio know-how and community history!

Sunrise on Ilion, a xenobiology project by @supermalmoworld, is a personal favorite of mine. Ilion is a planet tidally locked to a red dwarf star, and its endemic lifeforms often challenge our expectations for Earth-like ecology. The website boasts extremely detailed information on the setting and its inhabitants, as well as in-universe articles and logs of the various human expeditions to this fascinating world. The project is still active on a very sporadic basis, at least as per blog entries.

Nereus is a xenobiology project created by Evan Black; another reasonably well-known golden age work but one that is unfortunately no longer active. The world of Nereus, orbiting the star Achird, teems with life unfamiliar to the humans which seek to adopt it as their home. Like many specbio projects it adopts a documentarian style, but there are plenty of nuggets of story tucked in the articles.

Serina is a contemporary speculative evolution project created by the legendary Sheather; it is what I would consider the holotype of the "seed-world" branch of specbio. Serina is a planet populated only by the descendants of the domestic canary (and a few other organisms like guppies, snails, ants, sunflowers, bamboo, algae, etc). The project digs deeply into the various unique niches of the world and the organisms that evolve to fill them, and in doing so mixes nature-documentarian style with some of the most compelling and emotionally engaging storytelling I have read in years.

These are just what I think are the essentials. There are numerous other fantastic projects, both contemporary and from years ago, that I would highly suggest investigating! Contemporary honorable mentions that personally inspire me include @alexriesart's birrin, @iguanodont's birgs, @jayrockin's Runaway to the Stars, Christian Cline's Teeming Universe, Keenan Taylor's Kaimere, and my friend Mičkin's Temere!

Introductory Post

Hello, and welcome to my blog! Above is an infographic I've made detailing the Milky Way as well as the commonality of life and intelligence itself across the galaxy, which will serve as an important base of reference for all else I plan to post on this blog. I won't say much in reference to this image that isn't already included in the infographic, so I'll go on to explain what my project is about, which I will elaborate on with future posts:

In short, the primary focus of my speculative biology sci-fi project takes place around the mid-Centaurus arm, as indicated on the infographic, in a region of the galaxy locally known as "Ruminaaan Space", which is the single largest interstellar community in the history of the Milky Way! Although the majority of these Ruminaaan residents have only began their joint interstellar societies within the past 3,000 years, an ongoing battle has been waging for the past billion years and counting between a species known as the Yn and an entity known as Xii, and while I'll leave more detailed elaborations for future posts, this is a story of a single species divided and disfigured by their own conflicts and the long-term consequences it holds on their stellar neighbours, even one billion years later.

Onto the blog itself, to help with organisation, I will use the following tags on my posts:

#Alien Person Asks (for when I answer asks in my inbox (feel free to send any if you want to know more about my world!)), #Ruminaaan Theomachy (for posts relating to the central aliens of my project and the communities they've built), #Alien Person Spec Bio (for posts relating to the more biological aspects of my worldbuilding) and #Alien Person Worldbuilding (for other posts about miscellaneous or more general features of my worldbuilding process)

Besides transcripts for the featured image, that's all for my introductory post, so stay tuned for more!

{Main text-wall transcript}:

The Milky Way The Milky Way is a spiral galaxy about 100,000 light years across, which happens to be the galaxy in which Humans are located, as well as over a couple hundred other intelligent species. The galaxy is estimated to be about 13.6 billion years of age and has thus far been identified with two major arms (the Perseus and Scutum-Centaurus Arms) which branch off into many smaller minor arms.

The galaxy is estimated to contain anywhere between 100 to 400 billion stars, most of which host a minimum of one orbiting planet. Although on Earth many may consider the possibility of extraterrestrial life to be a rarity, it is more common than one may think, with there being roughly 14.33 billion planets and moons combined which host native life. However, only about 8.59 million of these worlds host multicellular life (around 0.06% out of the total life-bearing celestial bodies), which is due to eukaryotic multicellularity being a very challenging hurdle to get over for life everywhere for a variety of reasons. This being said, approximately 91.67% of these worlds do host sapient life forms, as high intelligence is almost an inevitability with multicellular organisms given sufficient time, though an extremely lower fraction of these planets and moons are actually home to sophont, technological civilisations comparable to anything humanity has accomplished throughout the past 200,000 years, with there being only 237 star systems with native sophont life (as indicated by the bright white dots shown to the right), and 268 sophont species overall, accounting for only 0.000028% of worlds with multicellular lifeforms. Among these 268 civilisations, very few actually aspire to be spacefaring, with there being less than 40 such civilisations, such as the Jodomii or Sirt, who even have space programs to begin with. Most either do not have the desire to explore outer space, as is the case with the Shreau, Uut, Samrinians or Aniin, do not even have the means to discover that outer-space exists in the first place, such as the Fline or Udrae, who have limited or nonexistent vision, or the Katudit, who live in the subglacial oceans of a rogue planet, or may never leave their home planets for any other multitude of reasons. While the abundance of technological, cultured civilisations across the Milky Way is fortunately higher than most may be led to believe, it’s important to keep in mind the fact that the space which separates the majority of these civilisations is tremendous, with even the closest being hundreds of light years apart. Despite this, only four interspecies interstellar communities have managed to spring up across the interstellar medium (not counting the Yuruuc, who have yet to encounter any other intelligent species despite how far they have dispersed throughout their corner of the Outer Arm), which is simply due to the fact that interstellar travel is nigh-impossible without the use of warp technology, though only one of these such communities has managed to grow to such an extensive size which incorporates over a dozen unique civilisations; Ruminaaan Space. Ruminaaan Space (the blue area marked along the mid-Centaurus Arm) is the single largest community of interstellar civilisations with the widest reach in interstellar space in the entire history of the Milky Way thus far, with the Boueue and Scerere only having came into contact nearly 3,000 years ago. This region of the Milky Way will be the main focus of my ongoing project, titled ‘Ruminaaan Theomachy’, as you’ll all get to see more of as time goes on, so stay tuned, and welcome to the Ruminaaan Theomachy project!

Nobody asked for this but it's time for an essay on Spock's body temperature.

Some people say Spock would have a hot body temperature because he is from a hot planet.

Others say he would have a cold body temperature because he is from a hot planet.

It seemed to me that we could test this thesis! Do animals from hot climates have a hotter or colder body temperature than animals from cold climates?

Humans have a roughly average temperature for mammals, 98.6 F (37 C).

Penguins have a core temperature of 100-102 F. Polar bears have a temperature of 98-99 just like we do. They can maintain this temp even in 40 below zero temps!

What about hot weather animals? The camel can vary from 93-104 F—a huge range, but on average around the same as ours. The elephant also has a large range, 95-99 F.

The coldest-blooded mammal is the echidna, at 89 F. The hottest is the hummingbird, at 107. Neither of these is from an extreme environment. It's more about the metabolism: the echidna's is slow and the hummingbird's is fast.

And yet, you see the range is not very great among mammals. This is because many enzymes work efficiently at these temperatures. Above about 104 F, some start breaking down. By 131 F, there's not much enzyme activity that can happen.

Okay, so: Vulcans. We know that they will not have an especially warm or cool body temperature because of the climate. Since they're warm blooded (an assumption, I admit! But I will defend it later) they will have an ideal core temperature their body will function best at and have features to maintain that despite the heat.

Note: Vulcans can also survive more extreme cold than humans; that's why Spock has to help Bones in a blizzard in All Our Yesterdays. This makes sense to me, because desert climates like Vulcan are prone to extremes. It might get very cold there at night with little moisture to trap the heat. This is one reason I think Vulcans are warm-blooded—a cold-blooded creature would have been useless in a blizzard. The other reason is that cold blooded creatures have a slower metabolism in general, and Spock could not possibly be described as slow moving or slow thinking.

Okay, so what is the Vulcan metabolism? Is it faster or slower than humans? My guess is faster, because of their fast heart rate, strength, and quick thinking. That said, we don't have solid proof either way. It might make sense for them to have a slower metabolism so that their body produces less heat and is less likely to get into the enzyme denaturing zone on a hot Vulcan day.

Which brings us to another question: how do they beat the heat? They seem perfectly comfortable in their climate, they're not using behavioral practices to stay cool as humans from hot climates do. They must have ways to efficiently radiate heat from their core. Those ears, for instance. Remember elephants? Their huge, flappy ears are a major cooling mechanism for them. They are able to push more blood through the small capillaries of their ears in hot weather and restrict it when the temperature drops at night. This is called vasodilation—controlling blood flow to either shed or retain heat. We do it too, though not as much. When you're hot, your ears will be hotter. Out in the cold, your fingers and toes will get much colder than your core.

Like camels, elephants can maintain a larger range of body temperatures than humans can. That's another coping technique they have. Other ways to shed heat include sweat and panting.

I never really imagined Vulcans as very sweaty. In a desert climate, methods of cooling that involve water loss wouldn't be ideal.

Here's my guess: they are extremely efficient at regulating core temperature by controlling blood flow. In hot temperatures, their skin and especially their ears would be hot, but their insides would be maybe 100 degrees. When it cools down, their skin would be very cool to the touch, but they would keep a core temperature in the 90s. They might also be able to speed up and slow down their metabolism somewhat to control their temperature.

So. On the Enterprise, which is kept at a comfortable temperature for humans...I think Spock would be a little chilly to cuddle. If you want a warm cuddle with Spock, go to his quarters, where he keeps it nice and toasty.

This has been my xenobiology deep dive for today.

Fun fact; Téoloni eyes often resemble gemstones, for example Nao’s eyes have the colors and patterns of malachite!

Fun Fact Friday

Niutéhian flora and fauna are closer evolutionarily than the animals and plants here, countless animal species have photosynthetic regions on their bodies and some plants have greater mobility and even muscle-like structures

Tried something new this time with no lines! It's weirdly.. cushy. I like it! Anyway, here's another one of my aliens; a Euphorian.

Euphorians also go by transmutationals, true angels, or transmogrifiers because of their unique ability to become pretty much anything. They are an ascended species, a living consciousness taken from its original host and molded into its own corporeal form. They're gooey and smell like birthday cake, and they love love LOVE those rock sugar sticks. They can never go back to the form they left to be this way, only temporarily as a disguise. They're very friendly and incredibly ticklish.

Headcanons for Haters anatomy! Ive had these floating about and decided to finally jot them down properly!

Its mostly weird and icky jelly stuff that changes in consistency and even opacity depending on its function and purpose. It resides within his bones for the most part but seeps out whenever he gets a cut or injured or needs some extra protection, so it gets extra goopy and bad when something makes its way past the layers of bone and into the system within. The first time he got properly sick in the skullship it was a nightmare for the little guys. (Picture sm similar to that scene in Howls Moving Castle)

But this does help explain how hes so immune to Captain Tim and their scratches and bites and acid fuelled "kisses". Hes doing alot of repairing and rebuilding without even realising. As well as the jelly being very effective against most types of acids and keeping any other unwanted inruders out of his system.

Very little is known about how he functions and he barely knows how he works himself despite years of being alive so its quite a scare when he actually does get properly hurt or sick. His senses are also pretty dull on the outer layers, which definitely didn't influence his relationship to pain and torturing and not getting why his fleshy companions make such a big deal out of it.

But the sudden sensory input when the jelly gets involved can be surprising and even upsetting, anything more than a loose flowy robe is suddenly really annoying and distracting to wear. A little like moving from the amount of sensation in ones teeth, to the amount of sensation in the gums.

Just a guy and his lap spider

Hailing from the harsh planet of Ettera, Knights are the only sophont in the Zhagaviit system made of two consciousnesses. ---

At last, here they are! Nearly finished with redesigning every Vivere 44 species. These guys are retconned werewolves which I posted about some time ago. You might have noticed I brought back some space unicorn aspects as well! They've been through so many design changes but I've finally settled on something solid.

More information below!

I'll try to keep this concise. Most of this info is introductory biology.

Knights are the only sophonts living on Ettera, a mostly barren planet where survival is tough. Their civilisation is the least advanced compared to others in Zhagaviit, such as Arrows and Sea Crawlers. They were the third species to be contacted by the ZGC (Zhagaviit Galactic Community) followed by Post Humanity. Knights are known for being hardy, efficient, and motivated.

If it isn't already clear enough, Knights are two species in a symbiotic relationship acting as one individual. Helmets and Hosts have an evolutionary history so intertwined that one cannot survive without the other.

The Helmet is attached to the head of the Host, and will remain there for the rest of their life (unless separation happens - but we'll get into that later). In the relationship, their role is vision and dexterity. Since the Host is effectively blind, it is the Helmet's job to guide them. Their hands are also important, being the Knight's primary manipulators. They played a large part in early tool use. The Helmet lacks a mouth, and receives all its nutrients from the Host through a specialised organ not unlike an umbilical cord.

The Host is essentially the main body of the Knight. Wolflike and mammalian in nature, the Host is the Helmet's mode of transportation. Because they need to eat for two, Hosts are omnivorous and will eat just about anything. Although majority of their diet is comprised of meat, they are capable of digesting plant matter and bones. They are highly skilled and effective hunters.

It is in both party's best interests to assimilate as soon as possible. The Host cannot see without a Helmet, and within a few weeks bonding will become impossible. The stakes are higher for a newborn Helmet, because they cannot feed by themselves and will starve in under a week without a Host or an artificial feeder tube. Prior to first contact with the ZGC, Knights did not have the technology for artificial feeders, and infant death rates were high.

So how do two beings coordinate one body? The fact is that once assimilation occurs, they become one being. The Helmet's brain and the Host's brain are connected by millions of nerves exchanging signals. It's complicated, but the best way to describe the experience would be a 'mutual trance' in which full body coordination is achieved. They have shared interests and intentions. However, a Knight can mentally separate the Helmet and the Host, gaining back individuality; they do this for many reasons, perhaps to discuss something among themselves or simply for company. Yet on the whole, a Knight will spend 80% of their life in this 'trance'.

Both Helmets and Hosts have noticeable sexual dimorphism. Male Helmets are called Pikes, and females are called Guards. Pikes are distinguished by their horn, bold stripes, and more prominent crest spines. Guards lack a horn and have less contrast in their thinner markings.

Female Hosts are called Forts. They are larger than males and have a mane of fur on the back of their necks. Male Hosts, Spires, lack this mane.

In Knight society, individuals are usually referred to based on their combination of Host and Helmet. Since there are four sexes involved, there are four possible combinations.

Guard-spire [female Helmet, male Host]

Pike-fort [male Helmet, female Host]

Guard-fort [female Helmet, female Host]

Pike-spire [male Helmet, male Host]

(Knight languages have their own version of pronouns for each, but in English all are referred to as they/them by default. Of course, each individual has their own preferences. Usually a Knight will refer to themselves as we/us).
