#speculative biology
Some old work I found in my DeviantArt gallery. Not fully satisfied with the text anymore, and the artwork is honestly kinda crappy, but eh. Reposting it here with only minor edits.
https://www.deviantart.com/concavenator/art/Ktykkryt-428955777
Contact: The Ktykkryt were the first extrasolar civilization to meet mankind, in the late 21st century. Despite the 20 light years that separate Delta Pavonis from the Sun, Ktykkryt have devised a technology to transmit messages faster than the speed of light (though still not at infinite speed), allowing a faster communication, if not travel; currently, human engineers are trying to replicate it from their instructions.
The world: The world of the Ktykkryt is slightly smaller than Earth, and its gravity is little more than half as Earth’s due to a much lower metal content (and thus lower density). Because of this, the tectonic activity is weak, and over 90% of the planet is covered in water; only a few volcanic peaks emerge from the global ocean. The magnetic field is also weak, and the few lifeforms that reached dry land are covered by thick shells or carapaces to protect themselves from dehydration and radiations. These islands, small and far apart, host highly divergent biotas, usually dominated by thin, spiraling trees and invertebrate quadrupeds, some of them giraffe-like with spindly legs and necks.
The species:
Body structure: On the whole, Ktykkryt look more like arthropods than any other terran organism. Their back is covered by a flat shell, and the rest of the body is protected by a flexible exoskeleton. Despite having evolved by centipede-like organisms, they have only four walking limbs (each of them ending in a claw and a soft pad); the other limbs either disappeared or clustered on the head. Some of these have been adapted into jaws, other in chelipeds (pincers) and one pair in tactile feelers. Their overall weight ranges between 10 and 20 kg, and even with their neck raised they rarely stand more than 60 cm high.
Metabolism: Ktykkryt’s ancestors used to live in large colonies to be protected by predators, reminiscent of bait fish schools, with little cooperative behavior; as a result, cannibalism was common whenever food supply became scarce. Today, the need for cooperation within a society has made it untenable, though ritual cannibalism is still widespread in most Ktykkryt cultures. They prefer hard foods, such as nut-like seedpods and armoured invertebrates, which they crush between multiple jaws and break down with powerful gastric juices.
Perception: As they descend from burrowing ancestors (re-adapted to life on the surface in the last 15 million years), Ktykkryt’s main sense is touch, supplied by long whiskers on each major joint and by a pair of feathery appendages on the head; to communicate, two Ktykkryt touch each other’s feelers and transmit slight movements and vibrations. Sight and hearing are less developed (in fact, eyes lack a fovea or pupil and see only blurry shadows), though there is a minor vocal component of communication. The word “Ktykkryt” is a rough human approximation of the chirping sound they make when referring to themselves, overlooking the tactile component.
Reproduction: Every Ktykkryt is born as a soft-bodied, barely sentient larva, given birth to through a thoracic cloaca and raised until puberty in a nest of slime (usually synthetical in modern times). At this point, the two sexes diverge: while females grow a strong exoskeleton, a large brain, a refined digestive system, etc., males develop only their sexual organs and reabsorb most other organs. The last act of a female Ktykkryt before leaving the nest is choosing a male sibling to implant in her cloaca, where it will be fed with the lymph of a specialized thoracic patch and continuously fecundating the female’s eggs.Culture: The approach to the males varies from culture to culture: some peoples treat them as if they were sapient beings capable of communication (there is indeed some limited exchange of chemical signals between the two bodies), while others consider their sight shameful and hide them under elaborate garments. Ktykkryt society is based on strong and fluid hierarchies, being born almost entirely from forced cooperation rather than pro-social instincts, and adults try to spend as much time alone as possible; in recent times, telecommunication have almost entirely replaced personal interactions.
View of humans: The first impression Ktykkryt can have of humans is intimidating: over three times as high and five times as heavy, typical humans tower over them, and could easily kill them with their bare hands. Humans also live in impossibly huge crowds, and appear to have a nearly psychotic obsession with interactions with their kin, most notably sexual relations, whose nature is entirely alien to Ktykkryts. When talking to one, a human should keep distance and communicate obliquely unless explicit permission otherwise is given. Many Ktykkryt also have reported to be deeply unnerved by how human larvae can already think and speak almost like adults; thus, interaction between them and Ktykkryt is discouraged, with case-by-case exceptions.

https://www.deviantart.com/concavenator/art/Yuulaana-429189964(2014)
Contact: Yuulaana were contacted by humans soon after the Ktykkryt, which had already known both species for a few decades, although sharing little information. They were also the first exosolar species to accept the physical presence of humans on their planet.
The world: The planet inhabited by Yuulaana is a lush super-Earth, about twice as massive as the human homeworld. Most of its landmasses are islands ranging in size between Madagascar and Australia, kept warm and humid by a lucky combination of wind and sea currents. Most of these islands, except for rare inland deserts and uplands, are covered by thick rainforests with orange-red plants; the air is dense and rich in carbon dioxide and water vapor, the resulting greenhouse effect more than compensating for a somewhat colder sun. The biomass is astonishingly high, and at least three different phyla represented in the megafauna.
The species:
Body structure: Yuulaana are mid-sized quadrupeds roughly equine in shape, with robust legs apt to run and leap; the body is built around a series of circular ribs connected by two spines. The head is very large and round, with two pair of dark eyes and a short, smooth snout that vaguely recalls a dolphin. A wide, leaf-shaped tail covers the pelvic genital area. A gular pouch stores a large muscular tongue, extremely sensitive to touch, that equals in length the rest of the body when fully extended; this tongue is also the main organ of manipulation, thanks to a hand-shaped structure.
Metabolism: Having evolved in a rainforest, Yuulaana are omnivores, with a strong preference for sugar-rich “plant” matter. Fruit-like food is usually swallowed whole, or grossly cut with a knife, and digested in twin stomachs. Alcoholic beverages, prepared with the fermentation of these fruits, are also appreciated. On occasion, Yuulaana consume “animal” tissue, usually enriched with many types of sauces and spices. Several cultures extract undigested seeds from their own waste and grind them into a sort of flour, though this custom is not very widespread.
Perception: Yuulaana’s sight is at least on par with humans, thanks to quadricromic eyes with lens and pupil, but they especially excel in hearing; their vocalizations, ranging from infrasonic to ultrasonic and competing in complexity with dolphins and songbirds, are reported to be very pleasant for humans. As with Ktykkryt, “Yuulaana” is an attempt to replicate the word for themselves in the most widespread language.
Reproduction: Like humans, Yuulaana are a disexual species, with haploid gametes that are fused in a diploid zygote via internal fecundation; however, the zygote divides through meiosis into several haploid embryos, resulting always in multi-gemellary pregnancies. The embryos are stored in the thorax for roughly a local year, and then given birth through a posterior genital opening. Since haploid organisms cannot carry recessive pathologies, inbreeding poses no danger to Yuulaana lineages, and is in fact common, especially in early years of life.
The culture: As a general rule, Yuulaana appreciate greatly art, music and body ornamentation, taking great pride in their athletic performance and/or in their esthetical appeal. Elaborate sexual intercourse is very frequent in Yuulaana society, as social binding agent, entertainment, or exhibition. As the hand-tongue - along with the sets of actual genitals and various artificial implements - features heavily in their sexual customs, the first Yuulaana ambassadors took great interest in the discovery that a handshake is a common human greeting. Note that specialized contraception has never been developed, as pregnancy and childbirth are part of the sexual experience in all known cultures. As a result, combined with the multi-gemellary nature of all pregnancies, most Yuulaana have several hundreds of children, only about 2% of which reach one local year of age. The rest is usually consumed by parents and older siblings.
View of humans: The reluctance of humans to take part in local sexual customs is often puzzling and distressing to the Yuulaana, which consider it a crucial part of social relations. The extreme attachment of human parents to a very small number of children, despite their ability of producing many more in replacement, can be outright disturbing. However, they appreciate human company, especially sharing their interest for music, visual arts, and athletic competition. Several forms and styles of human music are highly popular.

I can finally plug the project that I’ve had to shut up about! I was fortunate enough to be part of the Almost Real Zine, a speculative biology anthology of different mythical beings, but described by modern science. Here’s a sneak peak at my entry, the unicorn.
There’s some neat perks for backers and some cool stretch goals too, check it out HERE
Approaching the halfway point! If you cant/don’t wanna pledge, you can still help us out by reblogging, sharing or otherwise cross posting to get the word out. Much appreciated!
Hey check this out! It looks rad.
a selection of the megafaunal birds and rodents endemic to the Red Rock archipelago, homeland of the sole remaining archin (giant sapient bees lol) people.
the descendents of seabirds and castaway rats fill most vertebrate niches, with a few unique families developing here seen nowhere else. two of these translate to “groundbirds” and “hoofrats”, the former being flightless birds with vestigial/absent wings, the latter being large rodents who have developed hooves.
the biggest examples are shown here. descriptions under the cut
(youll notice most of the names here seem very literal- archin language is a visual sign language and thus the unique signs for specific words are either untranslatable into phonetic languages or must be translated literally like such)
left to right:
‘assassin moundbuilder’: large solitary ambush predator groundbirds who kick prey to death with their enlongated middle claws. males build and compete over mounds which females lay their eggs in. there are a few (much smaller) moundbuilder species.
‘birdmouth’:midsized predatory hoofrats whose incisors have taken on a self-sharpening, beaklike shape to better tear open the flesh of its prey. they live in colonies and show great behavioral plasticity depending on the environment- some clans will hunt alone or in loose groups for small prey, some are specialists of large animals.
’nightwalker’:this one isnt a groundbird at all but a species of heron and a relatively recent addition to the ecosystem. they are nocturnal (likely to minimize competition with comparable birds, mostly diurnal) and hunt both on land and in water, as well as scavenge. they are one of the more dangerous species to archin with the least adaptive fear of their guns, and will occasionally prey on them
middle: archin (and mrinitialman default human silhouette) for reference.
‘reinbird’ ‘reined shrieker’: a mid-large omnivorous groundbird that has been widely domesticated as mounts for archin. domestic populations have very long wattles regardless of sex, which may be used or augmented as reins for a rider.
‘twilight shrieker’: a very large, mostly frugivorous groundbird closely related to the reinbird. its named for its resemblance to an evening sky (sunset on one end, starry in the others) and the haunting territorial calls of the male.
‘mudleg rat’ the smallest hoofrat, this is an omnivore that fills a similar niche to pigs, and will opportunistically eat almost anything. these are occasionally kept as livestock.
‘maned leaper’: a group of mid-sized highly cursorial hoofrats, who fill a very similar niche to deer. they are a favored prey of birdmouths, and will leap and kick high in the air while fleeing to confuse predators
‘the ground shakes’: a massive herbivorous hoofrat who could be considered somewhat analogous to a hippo. while they are exclusive herbivores, they are very aggressive and can do tremendous damage to archin settlements with their mere presence. a naming taboo has developed as a result- there is no specific sign for this animal and it is referred to in the abstract (in hopes of not attracting them). ‘the ground shakes’ is a common phrase, or occasionally the slightly more specific ‘giant’.
Oldies from 2018 that I think still have some charm
Gonçalo’s banded wyrm, a marine wyvern from the central Atlantic island of Antillia. It occupies an ecological niche similar to that of seals and was well-known to sailors and sea captains who often observed them basking in the sun on the rocky Antillian coast.
This post is a reminder to all intergalactic citizens but especially those within the fixed universe to please be extremely critical of any “cute” videos that involve humans (bipedal hominid organisms from Earth, Milky Way, Laniakea)
I have noticed a significant uptick in viral content containing this species (probably thanks to Xarqrets Kain’s recent “Universe’s Cutest Aliens: Sol” series ) and I am very concerned with how humans are treated to produce such content. We all love seeing cute human videos, so let’s break down how we can ensure the content we’re consuming is ethical!
Red Flag Human videos to watch out for:
ANY video featuring a human on a planet other than their native home of Earth.
- These videos are particularly concerning considering the increasingly pervasive (and highly illegal) human pet trade. Humans are a remarkably adaptable species, but even those who appear well-adjusted to life on another planet are in great danger. Exposure to novel pathogens in humans are not well-studied and any human placed in a new environment could be at risk of death or corruption. These creatures are also highly gregarious and removal from their established social group on Earth can be detrimental to health and well-being. Responsible scientists will only remove humans from their planet as a last resort.
Be cautious of videos that show humans inside their homes
- Access inside human domiciles is highly restricted to legitimate research studies only, and bootleg streams from illegally placed monitoring systems are highly unethical. If you are curious about how humans behave in their homes, please seek out streams from accredited research organizations that have collected footage by methods undetectable to humans!
Beware of content that shows captive humans engaged in dangerous situations
- Humans are illegal to own for many reasons, but one of the most crucial is that this species has a dangerous tendency to get into things they should not. Humans are pathologically curious, and captive humans (especially bored ones) WILL find the most dangerous place in their environment to “explore”. I recently saw a video circulating of someone’s pet human approaching a field of Termakhan, solely because it wanted to get a better look at them. I shouldn’t have to tell you how dangerous that situation was.
This one should really be a no-brainer by now but please do NOT share videos where humans are curled into a ball on the ground or producing excessively intense acoustic waves. These are signs of extreme distress in humans!!
- The unfortunate reality of most encounters with humans (by non-trained individuals) is that they are highly frightening to the humans involved. That “adorable” video of a human vibrating the air molecules around it to an extraordinary degree when touched is actually an example of a behavior that is now well documented as an extreme stress response called “screaming”. Just because humans display fear in a way we don’t immediately recognize does not mean they’re not distressed by contact with us.
There is plenty of safe and ethical human content you can find if you look, and there is really no reason to support videos that put this amazing species at risk! Instead, seek out videos of adorable humans exhibiting normal behavior in their natural habitat on their planet- walking along coastlines, interacting with other species’ on their planet, playing with their young (so cute!), sharing meals with one another, and so on. Do your part to limit the human pet trade and avoid media that endangers or distresses these creatures just to make a “cute” video!
Ophis Pterotos, the double-winged serpent:
Tiny, colorful dragons native to the Arabian Peninsula are known to swarm around Frankincense trees in early spring, possibly attracted by the scent to form mating swarms. The males die shortly after mating, and may be fed on by the females as they prepare to migrate to their nesting sites. The Egyptian ibis is said to have a particular taste for these tiny creatures, which often die of exhaustion after laying their eggs near the Nile.
These strange beast were first documented by the Greek historian Heredotus, who wrote of Arabians burning “smoke of the storax” (another aromatic plant) to disperse their swarms in order to harvest resin from the trees.

Long, bottle-brushlike filter feeders sway gently behind them, their delicate tentacles protected by needle sharp spines nestled among them.
A rush of air, a shadow, and suddenly, a sickening WHACK
Such is the method of ehkusuiit Ik, the Cliff Striker. Long spurs on its forelegs are a formidable weapon for dispatching prey. Before the target can regain its footing, the cliffstriker will land to finish the job..
Its usual prey are flagdeer, but they have earned a formidable reputation among herders for knocking mounted birgs right off their trunkhorses. All the more reason not to venture alone into backcountry!
Cliffstrikers have symmetrical feeding arms (unlike Zhuuwhip), and the ability to rotate their eye plate to remain level with the ground. Their young can fly within a few days of hatching, but lack spurs. Instead, they cling to the back of their mother and scavenge her kills for the first few months of life, until they they grow large enough to hunt rat sized animals on their own.
Coupla nude birg sketches, still working on drawing their anatomy consistently
Some notes: most of the mid-arm rotation ability is in the shoulder, but they might have some extra flexibility of the wrist too. Nowhere near the range of human arms though.
Birgs tend to look a bit walleyed from the front; their evolutionary history as prey animals favors a wider scope of vision. They can look directly forward, but it takes conscious effort.
Revised birdbug skeleton, for anyone interested. The ancestral animal had an exoskeleton, which became heavily reduced in later forms. As a result, many of the muscle attachments are still internal. Birgs and their kin have convergently developed vertebrae to support the neck region, but the abdomen does not require this level of mobility and is instead surrounded by a cage of free floating ribs.
One of the most ubiquitous food crops in Twowi cuisine is this tuber-like “fungus” known as tsa-tsuúsh. These organisms serve as the roots of a host feathervane; collecting and storing nutrients, feeding the growing sprouts in the spring, and consuming dead hosts in the fall. The nodules are typically harvested in late fall, when the ground is not yet frozen but the tsa-tsuúsh are primed for overwintering. The example shown above is but one cultivar of hundreds observed across the Twowi empire.
A single nodule can connect to multiple individual plants; if no established nodules are nearby, spores within the body of the feathervane’s “walking seed” will still develop into roots for the sprouting plant and begin to form a new nodule over the course of several months.
Our guide rests in the shade of the Vherr-osh, the great sunspires. These glittering towers are composed of thousands of tiny chambers like the units of a compound eye, the inside of each lined with a photosynthetic “retina” protected from the extremes of the subarctic winters and summers.
The units are capped by a convex silica lens that refracts light into the chamber to maximize surface area for photosynthesis, while protecting the delicate living cells inside. The reflective lining beneath the lens thickens at the height of summer to prevent overexposure, and is also responsible creates a striking violet iridescence. The lenses are likely derived from silica spicules in the ancestral species; extant relatives still bear these spicules for anti-predation and structure.
These strange trees grow slowly, taking centuries to reach even 5 feet in height. Accounts from the nomads of the region suggest they can live for thousands of years beyond that. A Tuin clan legend attests that they first grew from the shed scales of a primordial bird as it circled the newly formed world. Mature forests such as this were already vanishingly rare by the time I was lucky enough to lay eyes on one. The inhospitable region where they grow is seldom visited by birgs, though just a few centuries before, these lenses were scraped away by the hundreds of thousands to make all manner of decorative windows, sun catchers, even primitive spectacles and telescopes. To this day, some Twowi nobility covet the iridescent crystals as an exotic and expensive jewelry.

A Noumi clan child proudly displays their prized pets. These colorful scalebugs spend their larval stage in the bark of certain feathervane trees, where they are collected by local kids and raised to their adult stage. Their scales are prized for jewelry, but the living animals are also fashionable pets for kids and adults alike.
Some sketches of some creatures for @iguanodont’s Birgworld.
includes: that big old fossil dude
a larger, more wolf-like kin of the jaubja, that’s specialized for bringing down flagdeer and other “ungulates”
a bizarre, distant kin of the the birgs that’s got big ‘ol pinnae and a long, extended abdominal segment that’s like a dinosaurian balancing tail
some “ungulates”
and a “whale”.
These are wonderful!
Media that does the “ooh, the cave/dungeon/building/whatever is alive” bit always goes straight for exposed bone and viscera. Like, let’s get some integument in here – I wanna see a creepy living dungeon where the walls are furry.
But- but you’re *inside* the cave-
yeah it’s to keep the poor dungeon warm when the adventurers leAVE THE DAMN DOOR OPEN AGAIN
I mean, if your living dungeon has large, permanently open interior spaces that freely exchange atmosphere with the outside world and are intended to accommodate other creatures, those interior surfaces would need to have some sort of protective covering, if only to control moisture loss and prevent infection, and maintaining a mucus coating for that purpose just isn’t practicable at that scale. We’re talking skin of some description; while thick fur probably wouldn’t be necessary due to the surfaces in question being interior (and thus amply insulated), one can easily imagine that skin being fuzzy.
Ok so, here’s a funky fact: in the early evolution of fish, the claspers (reproductive organs still present in modern sharks) actually began as a genuine third pair of limbs. Sooo what if instead of becoming purely reproductive, the claspers instead developed into full on legs.
Basically what I’m saying here is six-finned fish -> hexapedal early tetrapods -> hexapedal temnospondyls -> hexapodal tiny weirdo arboreal dendrerpetids that develop membranes to glide -> amphibian dragons
they have little grabby hands and spurt venom out of their mouths and they are my precious new babies
Speaking of the arboreal proto-dragons, here’s the little guys!
My entire design aesthetic with these fellows is “little dudes I want to hold” and I for one think it’s working!
Good tags :)

but-what-if-realism-spoilt-this:
Revisiting fairies/pixies. Their family includes all the smallest members of the wyvern clade. These lil’ cuties build communal nests in a sheltered site such a tree hollow or the walls of an old house. The warmth and humidity of so many little bodies combined with the grass bedding and guano creates the perfect conditions for the growth of a toxic fungus related to ergot. Consumption by most other animals causes confusion and hallucinations, but the pixies themselves are immune. It readily grows among their winter stores of grain and berries, making it a nice symbiotic deterrent to thievery by other animals, particularly rodents and some insects. The spores collect as “pixie dust” in their fluff to be spread to future nest sites.
Long story short: do not eat the fairy fruits.
A wonderful reimagining of a mythological creature. The inclusion of a believable symbiosis with ergot really brings this concept to life. Ergotism (A.K.A. St. Anthony’s Fire) was a big problem in the middle ages and has been linked to witchcraft paranoia.
Although they don’t state it, it looks like they have zygodactyl feet like parrots too, which is a nice touch since it allows a lot of object manipulation.
