Okay, as an extension of my previous question, I'm just going to lay bare all the details I've written down about this planet (including corrections from my last question), and ask the big question...
If humans hadn't lost their tails and today we had fully prehensile tails as long as 1/2 our body and stronger than an arm, how would the tail of a bodybuilder or just a buff person look? Would tai...
just as the title, my question is can it possible for a creature that can reproduce with any/all creature despite it was different species/family? (not the alien xenomorph or parasite one/way but r...
To preface, my creatures have 4 horns, and they behave very similar to rams (at least ancestrally) in that they headbutt to resolve conflict/create dominance hierarchies. Two smaller horns are abov...
I understand, vaguely, how human voices vary with the overall size/shape of the individual(s vocal chords), and I can use that to make reasonable assumptions about what the voice of non-human fanta...
inspired by this question Wearing vs Growing Clothes and this link medical news today Chemical peels A chemical peel involves applying a chemical solution to wrinkly areas, causing the ...
Having read previous questions on radio wave communication on biological creatures would it make sense for race of alien creatures to have developed dish like bone structures for radio wave communi...
Inspired by One Piece by Eichiro Oda. from https://onepiece.fandom.com/wiki/Nikyu_Nikyu_no_Mi Fiction has many examples of humanoid animals - things like lycans or werewolves, cat/dog/rabbit fo...
Imagine a spacefaring creature, one that colonises star systems, and then shoots some of its kind on to another system (the mechanism for doing this doesn't matter). The question is, how could thi...
My planet is frequently set with thick fog. What is the best way to have its residents see accurately? One species called Hell Fires fall from the sky, landing on top of prey and killing it. How...
I imagine a biological creature, let's call it 'Marco' for now. Marco can vomit living slimes that survive by attaching to the ground and by doing photosynthesis, at first soft can be shaped and...
I want to have a species based on humans, where everyone is born as female, but switches gender to male later in their life. Assuming that transformation takes 4 years (*) hermaphrodite is born as ...
The Ozoa are a peculiar race. They are native to a large gas giant similar to Saturn and physically look similar to what we would call "jellyfish". Within their "head" the Ozoa contain a lifting ga...
It is inspired by this furry trout. I mean fish (not necessary to be a trout), not aquatic mammals, and real fur, not from fungi or mold (or looks like fur because of the dead cell, like Mirapinna...
I've quite a few alien species that utilize a non-food-based metabolism (one of them being nuclear power). Does a species that has a metabolism not based-on plants or meat (such as using nuclear ...
Thanks for taking a moment to help me understand the feasibility of this scenario. Essentially, what I am looking at is an Earth-like world that would be between 1.3x and 1.6x the mass of our own ...
There's iridium-based blood called Chloro-carbonyl-bis(triphenylphosphine)-iridium that's effective at transporting hydrogen alongside oxygen. What I want to know is that, are there other metal-ba...
(maybe this should be part of the "anatomically correct" series. If so, feel free to edit accordingly, as I don't know how to add it to that list) Could a roughly human sized, human weight, biped...
Since a lot of people are already asking about multiple-headed creatures, I wonder what about multiple tails? Such as kyuubi, nekomata, etc. (I know some have asked about these mythical creatures, ...
One common way sci-fi writers try to make their aliens seem more 'alien' is to give them an extra heart. This has been done for example in Babylon 5, Dr. Who and Alien Nation among others. But:...
I mean literally not sleeping for the rest of their life, not like giraffes that only require short rests, or dolphins that can sleep with half of their brain at a time, or like otters and sharks t...
One of the races in my sci-fi universe is the Ceratons a race of bipedal (more hunched build) that look similar to triceratops. Their race is well known as skilled geneticists having a hand in dis...
Some follow-up thoughts on this question... Hydrogen isn't very soluble in water. Oxygen is more so, but still sufficiently insoluble that most oxygen-breathing Earth creatures use special oxygen ...
Inspired from people walking on water using cornstarch plus myths such as monkey king, several gods in heaven/celestial palace, and other fiction works. (image from Dragon Ball by Akira Toriyama) ...
I've been working on this concept where a deadly new fungus starts spreading from two central locations. One in Europe and one outside of a major city in the United States. Over the course of 16 da...
Can we make a human brain and body the size of a mouse's while still retaining the same level, if not more intelligence? Like how tech has evolved to be smaller but more efficient or how cars are...
This question's information is based on the answer in my previous question about what the aquatic creature need in order to live or survive in my acid water? The thing that's not in the descriptio...
Inspired by the Paycheck and Minority Report movies. So far as I can tell, physical time travel is impossible for humans, and so I searched to see the future possible scientific or theoretical pos...
Edit: Okay, truth be known that this question was part of a set of 5 related questions that I was recommended to break up into individual posts (in their original form, the comments had no trouble ...
This post about a tidally-locked planet got me thinking about plants and wind. Let's say plants evolve on a perpetually windy, tidally-locked earth-like planet around a sun-like star at about 1 AU...
Form follows function, or that's how the saying goes. Which isn't true for some things. That is to say, a large reason why humans use a base 10 numbering system is because we have 10 fingers, not t...
inspire by xenomorph acid blood from alien movies. so the water either rivers, lakes, and oceans in my world or some of the regions is highly acidic because some of the dirt or stone minerals cont...
I was hypothesizing an organism that could create it's own fire with the use of a flamethrower-like organ. I was thinking that this animal has a oxygen-free organ that hold diethylzinc and when the...
Is it possible for life to evolve"” and survive"” on a planet that is regularly hit by [relatively small"” usually no more than a few feet across when they make an impact] meteorites? If so, what e...
We've seen it throughout media before, a crazy mutation that creates zombies, rabid people, giant spiders, etc. I'm spot checking how crazy I can get with this short story I'm writing about a bacte...
I am simply wondering if an organism could possess an enzyme that could ionize a noble gas such as argon, krypton, or xenon. I was thinking that the organism could obtain energy through light or ma...
This is a continuation of a question I made earlier! The atmosphere consists of 80% N2, 17% O2, 1% CO2, 1% NH3. I am not extremely familiar with the chemistry of ammonia, but I do know that it beh...
I am currently working on world-building a planet, and I wanted to try to diverge from Earth's atmosphere a little bit, but not extremely. I am planning on still having it be a oxygen-nitrogen rich...
So, I'm designing an alien race/civilisation of carnivore. I was thinking of a very aggressive specie, who is both the alpha predator of his world and his own main cause of death. Basically, a lo...
So I'm trying to design my alien life around the pressures they might face just like earth's wildlife, and most things I've made plausible life that is similar to ear but not giant dinosaur cats. T...
Concept: For some twisted reason, a xenocidal space-race living somewhere in our vicinity decides that nothing deserves to exist. So they make a species. Any feasible size, any kingdom. It eat...
I'm envisioning a setting in which human beings have altered themselves significantly to be able to live on alien worlds without significant terraforming. One type of transhuman needed would be on...
For certain reasons I decided to not set my story on Earth. However, the planet is meant to host an Earth-like biosphere (including humans, most of Earth's species (perhaps some that didn't evolve ...
Are there any unique challenges life would face evolving on a planet orbiting a Cepheid Variable star? I'm aware this is a broad question, so to narrow it down, consider this a question about Grea...
On my world, the equivalent of the Cambrian/Avalon explosion happened 5 byr (2 byr after formation) ago as opposed to 0.5 byr ago on Earth. The planets rough parameters are: mass between 0.4 and...
An interesting idea that popped up in my previous question on the feasibility of large scale life on a gas giant was a form of energy production similar to photosynthesis, instead absorbing the EM ...
Obviously, if available, atmospheric oxygen is a great source of energy. However, I'm surely not the first worldbuilder who wants an alien species which doesn't depend on it (whether due to having ...
Suppose that there is a substance that is produced in nature by an organism. This substance is rather desirable. The reason this substance is desirable can be anything: Whether it is because it is ...
So, i'm just searching around in spaceengine and got the idea of worldbuilding based on one of the planets that exists in the simulation (not quite worldbuilding in a complete sense, but speculatin...
Hello! I'm no scientist so I've reached the limit of my knowledge. I was wondering if any of you smart beans out there would be able to help me figure this out? Here are the specs of my system; Ke...
