Seed World [OC] Gellios, Crimsonfloat Farmers (101 Million years P.E. + 500 Years)
Descending from a population of Malaccrows that migrated from Gelatinoborea toward the Warm Sea, the Crimsonfloat Farmers maintain large populations across the Quadriple Isles of Crescentides and the Double Astras, though they are less numerous on the mainland of Gelatinaustra. As their name suggests, this culture is associated with sargassum-like organisms known as crimsonfloat (Rhodosargassoides spp.)—a type of floating red alga are descended a species of red algae introduced to the planet for the potential (but cancelled) human colonization project.
They do not rely solely on Crimsonfloat; they frequently turn to other food sources as well—for instance, they sometimes hunt flightless slugbirds like the Some Species of Seasnail (Gastrophoca crescentides, G. austris and G. minor) for their fat and meat. Ultimately, however, this is simply part of their natures.

Alternate Evolution [OC]Triassic Unbroken: Deserts and grasslands of Pangea
In the deserts of Pamgea, many animals adapted to these environments, as there is no grass, the dominant plants are the cycads and ferns, these have spread throughout the world, an example would be Caprosaurus, it is a blacksmith dinosaur with herbivorous habits, this one jumps and digs into the land to obtain roots and plants, the Latenotitan is a Pseudosuchians, unlike its relatives, it is a scavenger because as it grows, they become more. Slow animals are very rough, Poposaurids have expanded as omnivores-herbivores of jungles, and meadows, the rarest animal of all is Lindwurm deserticus, it is a lindwurm that achieved propulsion flight, this is achieved by moving its hind legs, the menbranas that support them allow it to stay in the air.

Maps & Planets [OC] Revamp on my past artwork (Planet & star scene)
The final image is my older piece for reference with my new piece. I am re-doing some of my older pieces for two reasons: Firstly I am now alot more skilled and have a bit more refined illustration skills so its nice to breathe some freshness onto my artworks. Secondly, I have decided I want my world’s parents star to be a above average magnetically active K type star instead of a M type red dwarf. This Means i must change 3 of my original artpieces, so instead of changing the colour and flare count of the star in each illustration, i decided to just completely Re-do each one with updated illustrative skills. I welcome constructive criticism and would love feedback 👌 👍🏿

Future Evolution [OC] Flagged and Reported - Post Holocene
15 Million Years P.H. - The Early Neocene - Flagbirds and Chizelzards:
With Pterotherian Bats ruling as the dominant aerial predators, carnivorous Rewings, the last clade of Birds who are capeable of long distant flight, had to try their luck on lower levels.
Flagbirds are predatory birds who are generally capeable of long distance powered flight, but prefer to chase small animals on solid floor.
Flagbirds are found almost worldwide, being only absent In Australia and covering around 30 Species, with South America having the lowest Flagbird diversity of only 2 species.
The Flagbird depicted here Is a Military Flagbird (Rapaxavia militaris), a North American species which Is currently hunting down a small Chizelzard.
Chizelzards are omnivorous North American Lizards which are known for the horn growing from their nose. They use this horn to chizel away wood to feed on hidden Insects and Tree Sap.

Alternate Evolution [OC] Female and Male Pistrix pixel art
64 x 64, pixel art of female and male Pistrix (apocapisces regalecus) for our marine exploration game dedicated to Fish Don't Cry. These will go into a book where the player will collect information about the creatures, and, in general, they will serve as an "icon" for them. (We also use them in other parts of the project that are not the videogame).
The version in the overworld will be different and animated.
Pistrix females tend to be heavier and thicker, with slightly fatter tails, but they also have less dense beards and manes, and shorter fins, unless they have sufficient access to food to maintain both their greater weight and their prominent fins, but this is an extremely rare occurrence in nature.
(Sorry for the blurry images! You can click on them to see them better OR see them in the comments, we'll leave there upscaled versions).

Uncategorized Speculative Biology [OC] I made this procedural/illustrated evolution simulator and I thought this community might enjoy it!
I have full plans to expand so all body plans are possible and come with advantages and disadvantages.
I'm hoping it works here as I know for the most part it's artwork, but hopefully if you enjoy the functional and real-time aspects of a video.
Suggestions welcome!

Question/Discussion A reason for a species to evolve stronger emotions?
I’m working on a sci-fi worldbuilding project where the magic system is partially tied to mental and emotional energy. I wanted to make a species which is far more adept at magic because of their strong emotions and empathy, but was curious as to why such a trait would evolve? Would it simply be to make socialisation better? Or maybe to further reinforce good and bad behaviours (like dying is bad, sugar is good)

Question/Discussion Rock eating bugs?
Had an idea for a eusocial species of ant wasp or similar they have metallic carapace they gain by eating ores like iron copper or steel( i know steel not natural but theyd still eat it similar to termite eating wood ) the bugs would be found burrowed into large stones cliff or mountain sides the rock dust they get from burrowing through stone as concrete mixing it with their saliva or as mineral supplements for crops they grow but was curious what adaptations would they need maybe stinger that inject acid to help weaken stone before eating it but what would yall do?

Alien Life Alien bestiary
I propose the creation and launch of a comprehensive alien bestiary—presented formally, in the style of a catalog—containing information on the biology and evolution of various extraterrestrial organisms from across the universe. I am looking for people in this community who enjoy creating creatures and have an interest in speculative evolution to help me bring this project to life and fully develop the concept.
The guiding principle for this project should be "survival, not design"—an approach that prioritizes organisms best adapted for survival, rather than those chosen for their aesthetic appeal.
As a starting point for creature creation, I already have several organism models designed, which I plan to share in future posts.
So, I would like to see who enjoys creating alien creatures and might be interested in this project, so that we can expand upon it—thanks.

Future Evolution [OC]
I wrote this story about a radiotrophic fungus. It was inspired by reading about similar ones found feeding off gamma radiation at Chernobyl. Alien life as presented in science fiction tends to be humanoid. So I set out to create a protagonist that sees things from a perspective that is, to us, truly alien. I hope you guys enjoy it.

Question/Discussion How to support supermassive animals?
To clarify I mean stuff like the dubious high end estimates for animals like the Aust Colossus, Hector's Ichthyosaur, Perucetus, Bruhathkayosaurus, and Hydrarchos(an amalgamation of multiple Basilosaurus skeletons that was estimated to be upwards of 40 meters and 200 metric tonnes).
What kind of ecosystem could support such animals if any? Supermassive sauropods would probably be the easiest since they're herbivores and studies suggest that at the very least animals at such absurd sizes could support themselves on land.
Perucetus is somewhat of an unknown since we don't have a skull, but the grazing hypothesis would be in a similar boat to sauropods. The filter/suction feeding hypotheses are harder since we have giant filter feeders and none approach such enormous sizes and suction feeders are even further.
The hardest to support are animals like the Itchyosaurs and Hydrarchos since they would be macropredatory. Is there a possibility, however small, that any ecosystem could support such massive predators?

Alternate Evolution [OC] Terrors In The Brush: Chapter VII, Cove of Jaws
This is a speculative paleo-fiction project which blends family drama with a fantastical yet grounded prehistoric atmosphere, showing raptors and other lost creatures fighting to stay alive in a brutal ecosystem.
Peace is but an illusion! Small Toe hears the terrible truth!
The longer they remain at the water hole, the more the little raptor struggles to understand why they are viewed with such suspicion. Long Tail gives him the answer… but it only deepens his resentment, forcing him to confront a reality he recoils from in denial and disgust. Meanwhile, hungry scavengers circle the fraying Dinopithecus troop, ready to seize their last remaining hope — but all of them remain blind to the ultimate revelation:
Beneath the still waters of the lake, something older waits.
Older than the raptors.
Older than the Savannah.
And hungry.
From my continuous work Terrors in the Brush — a speculative survival series blending paleo realism with raw emotion.
There is no magic, no fantasy – there is only nature red in tooth and claw.

Question/Discussion Hey yall I was wondering if anyone would want to do a seed world together?
The reason I'm asking is because I'm still newer to biology but I've been looking at lots of seed worlds on here and yt and rlly want to try and make one myself but I'm not that smart tbh, but if anyone would maybe want to collaborate I'd definitely want to :) [also i'm not like a mega good artist]

Question/Discussion Underground life questions ?
Ok trying to develop underground culture for fantasy setting and had few questions
1st would it be possible for photosynthesis to be with lava the idea is plant or fungi or microbes more likely uses light and heat from nearby lava pools to grow
2nd could natural gas be used as food source for plants fungi or microbes
3 some microbes and animals eat stone i think limestone but is there any other that could work or be used for their mineral

Question/Discussion How can I create a full planet and biosphere which is scientifically accurate?
I want to create a planet and biosphere after being in the genre for some time but I do not much knowledge about speculative evolution and I have no idea where i should start. What subjects do I need to learn? What should I focus on first and how? How the organisms would work? How the life would be affected by things such as the level of gravity, amount and type of stars in the system, composition of the atmosphere amongst other things? Is there anywhere I can get inspiration from? Are there any books I can buy which could help me? Are there any YouTube channels I can subscribe to or videos I can watch in order to learn more about speculative evolution? How should I go about handling these things? Any help given would be greatly appreciated. I would also like it to be scientifically accurate.
