BEHOLD! My Mushseed Zine!!! This is a zine that mimics what a pet care guide would be like on Arstiem within my story “Below the Surface”. I put a lot of effort and research into this so I hope you all find it as intriguing and fun as I do! Also sorry the colors look so dull, it's formatted for cmyk :,)

Full zine under the cut!

Heres a silly fantasy creature i made :D i call them Hopper Horses or Grasshopper Horses.

I have a name for this species now, they're called the Heriheri! This is Mitra, he's a different subspecies to Watama but they're both pretty similar. He is wearing a necklace of seed pods because they rattle, and that's useful since his job is feeding/sacrificing people to the Mother of the Deep, which is a massive blind cave creature a bit like an olm (she recognises the rattling sound and knows not to eat him). The long spines on his head can move, and he wiggles them about to show different emotions. They fall off every year and he grows new soft ones. Also, don't be fooled by Mitra's cute exterior and the fact that he's only about the size of a dog, this guy is Evil.

My horrible son, Watama. He is a sophont living in a series of caves in a big colony along with other creatures of his species (not sure what I will call them yet) and technically he is a subtroglophile since his species has to leave the caves to get food etc (they are omnivores but eat lots of bugs. Yummy). His species is nocturnal, hence the big sad wet eyes. Also his species usually wears clothes of some sort since it's quite cold where they live, I just haven't drawn them yet. Watama is a male, but like the Kerilone who he is distantly related to, when he reaches a certain age and body fat percentage, he'll become a female, and get a lot larger and more sedentary, and lose the red pigmentation around his chest spiracles. This won't happen for him for a long while though, since he's pretty skinny for a whatever-he-is, although you can't tell because of his thick layer of plumulaceous feathers. He is quite a drab example of his species, but they aren't generally super colourful anyway - there's not much point if you live in a dark cave.

Rilicai in the rain. Inspired by how rainy it is where I live at the moment. Rain is pretty common where she lives as well, but she doesn’t normally go to the forest - most of her species live in or on mountains.

Four Kerilone outfits for various occasions. Dyes are not very common and quite hard to make, so most everyday clothes are undyed as in the winter outfit. However, red and blue dye - red from a plant, blue from various shellfish - are available. Kerilone courting takes place in the summer. The Kerilone are protandrous hermaphrodites, which means they all hatch male and gain the ability to become female upon reaching maturity. Females are larger than males, with darker colouring, and are less agile but stronger than males. Every year in winter the Kerilone shed their summer coats and grow new, white and fluffy winter coats (not shown in the picture), as well as losing their sexual characteristics as well as their ability to reproduce - the winters are very harsh, so all of their energy is needed simply to survive. After the winter, young adults can become either male or female: they have a modicum of choice in the matter, but it is largely down to environmental influences. However, as they age they lose the ability to become male and remain female for the rest of their lives. Like most Earth species they do not go through a menopause, however the average amount of chicks a Kerilone will rear in their lifetime is only about ten.

So... My first actual post on this account! This is Rilicai, a Kerilone (race of vaguely equine sophonts) that I've been designing recently. She lives on a swampy planet orbiting a M-Class star.

So I’m going to actually do something with this blog.

About me: I am 21 years old and I’m into a lot of things. My name one here is armchairthinker is mostly because the  knowledge comes from credible sources I find on my couch 😂 (Trey the Explainer, North 02, Biblaridion, etc)

I won’t be saying I’m an expert but someone who has some common sense.

I’m also a writer and planning to show off what I got.

I am into world building and speculative evolution/fantasy. So most of my topics will be on that. I am also into paleontology.

If I seem off I am high functioning

Wyverns!!

Overtime in general all of the species evolved more talons! Right now they’re sitting at 5 talons per arm with 4 hind talons with Wyverns having an additional digit (6 & 5)

Finally, after a year, I’m updated my Elves. Here’s the High Elves! If you have questions, go ahead and ask! :)

In the image, the Elf is a mother, which is why her breasts are enlarged. She is feeding a baby. (I will draw the baby soon!)

There are two other Elf species I still need to draw: Wood Elves & Drow (Dark Elves)

DWARF LORE

Culturally, Dwarves place great value on storytelling, visual arts, and personal expression. Carving, painting, and storytelling are integral parts of community life, and many important events are marked with communal gatherings and storytelling.

Tattoos and braiding are also deeply significant. Both sexes grow facial and head hair, and this hair is a source of pride. It's common to see Dwarves with elaborately braided hair adorned with beads and charms. These beads carry symbolic weight, marking major life achievements like completing a coming-of-age ritual, raising children, or achieving mastery in a craft.

They live in cold climates, and their physiology reflects this: they have thick fur and tend to be shorter and stockier than humans, conserving heat efficiently. Their homes are primarily subterranean, dug into earth and rock. However, they also build above-ground structures using wood and stone. Settlements focus on function and community over grandeur.

Their diet consists mostly of vegetation and insects, though they are capable of eating meat in times of scarcity. They practice agriculture and cultivate various crops, and also keep domesticated animals — some for companionship, others for practical use like warmth, protection, or pest control.

As marsupials, their reproductive process is quite different from humans. They give birth to underdeveloped joeys, which continue to grow in the parent’s pouch. Dwarves (like some kangaroos) have two uteruses- one embryo can be carried in the pouch, while another remains in delayed development in the second uterus. This allows for a staggered cycle of birth and care. Young Dwarves gradually gain independence and are raised communally, with extended family and neighbors contributing to their upbringing.

Their social roles are flexible and can be shaped by skill, age, or experience rather than rigid gender norms. Celebrations often involve communal meals, storytelling, singing, and symbolic rituals like bead-giving or new tattoos.

(More art will be out soon! Please ask questions if you have questions!)

Go follow this new acc! It belongs to my bro who also posts spec bio content!!

Daezurian Dragon! Though my fellow specbio enthusiasts would enjoy :3

yes, i know there is absolutely no way these guys would be a les to fly lol. But, a man can try. Might colour this in one day,but behold the Daezurian Dragon! A sapient, omnivorous descendant of cynodonts.

despite being sapient, they lack empathy and their morals aren’t too high… but hey, cool dragon

(note: this is a repost from my main. You may have seen this before.)

LF Superman biology headcanons

Hey again, folks! I want to hear all of your Superman/Kryptonian biology headcanons! Here are some of my favs I’ve come across so far:

Detecting Heartbeats

One of my favorite headcanons comes from tOOthpasteface: Superman doesn’t just hear heartbeats—he can feel them. This is thanks to a Kryptonian equivalent of ampullae of Lorenzini, the specialized pores sharks use to detect electrical signals in their environment. These pores allow him to sense not only heartbeats but also electronics, electromagnetic fields, and changes in atmospheric conditions.

Photosynthesis

This one is practically canon but still worth celebrating. Kryptonians can absorb sunlight through their cells, converting it into energy much like plants do through photosynthesis. What I love about this idea is how deeply it ties Clark to the sun—not just as a power source but as a lifeline. Plus, there’s so much room to expand this idea: Does he store solar energy in specific organelles? Does his skin change subtly under a yellow sun compared to a red one?

I’m personally just such a big fan of alien biology and wish Clark was more outwardly alien in canon. I’d love to hear more ideas so I can add them to my collection!

Coloured version of raptor folk

Critique is always appreciated! <3

Sorry for the lack of posting! Here’s a WIP that I started a while ago- it’s my species of “raptor folk” (name is temporary). This one is a subspecies of desert dwelling aliens. Any suggestions for species names are appreciated!

I’m not super happy with the design yet as they’re quite like earth animals, so any tips are great aswell!

Hehe Minecraft glow squid 🤭

I’d love to hear your headcanons in the comments/reblogs

Glow Squid Headcanons?

What are your headcanons for the minecraft squid and glow squid? I plan on drawing them next and want to hear what others have to say! :)

Sorry for the lack of posting about world building stuff- I’ve been super busy working on trades, adopts and commissions! 😓

I’ve decided to make an alternate acc for posting art unrelated to speculative science, go follow me there if you’re interested in seeing fanart and cats! :)

Elves (Speculative Biology)

If elves were real, what do you think they’d descend from? Personally I find them being a subspecies to be a little bit boring. Please lmk!! I’m considering for my fantasy world

Does anyone else find that certain topics do better on different apps?

For example, on Tumblr my speculative biology, aliens and Minecraft stuff does really well, whereas any posts of cat or furry artwork does significantly worse. However instagram is the opposite- cats do well, and aliens don’t.

I just find it odd is all 🤔

Dwarves!

Here’s a little bit of info about the Dwarves from my fantasy world

I love answering questions, so please ask if you have any! Lmk if you want a part two, and what you would like me to include there!!

I’m bored what Minecraft mob should I post about next

Brainstorming Minecraft food lore :>

Strider Saddles

Response to @mesmerizms !:

In the initial art I did, I was a bit lazy with the saddle drawing, but I’ve made this to clarify some things!

Here’s a strider without a saddle, a strider with only a saddle blanket, a strider with a blanket and a saddle, and a strider with reins.

There’s lots of room for different colours and patterns on the blanket, including tassels like the one in the picture! There’s now a saddle horn and reins to hold onto (although I’m not sure how feasible they are), as well as stirrups.

Keep in mind, I’m basing this off of my prior knowledge + some cursory research. I’ve never ridden a horse or any other animal 😅

Minecraft nether chicken lore 😭

Finger lickin’ good

This is important for my next Nether lore/food post :)

ALIEN PLANT!!! :P

yeah ik it looks a wee bit funky 😭
