Satyrs, fauns, pan, and even the devil are commonly depicted as humanoid bipeds with goatlike unguligrade hooves for feet. However, common as such beings may be in fantasy and mythology, I have bee...
I'm trying to design a realistic genetically engineered nanotech super-soldier with a full set of redundant organs. How much more interior volume and thus height/weight/muscle mass would a human bo...
Could an artificial plant species be designed and created that lives in a vacuum - for example on the surface of our moon? The main problems I can see immediately would be the lack of an atmospher...
What adaptions would humans obtain if they lived on Mars? (eg. get taller/shorter because of gravity) In a universe where humans terraformed mars to have breathable air and house some plants, what...
So let's say that I have a world with a moon, you know kind of like we do on Earth. But with life on the planet, is it possible to find life on the moon? In the artifexian video on habitable moons,...
Imagine for a moment that a plant (let's say a maple tree, though any plant will do), has unlimited energy. There's no conversion of sunlight or anything - the energy is just there, being soaked di...
Related to this question on lack of human dimorphism, but hopefully the length of time my question has sat in the sandbox unremarked means that I have successfully been more specific. I'm writing ...
Of all the creatures in Hatjörn's dominion, there is none as peculiar as the Murinae Spirita, the mean booze-rat. A vermin so resilient that has developed the most wondrous means of defence and...

Let's start this whole question off by exorcising the negative connotations of the word from our minds. Out foul demons, OUT! Our fictional near-future world has no negative instances of slaver...
The traditional description of the mermaid is half-girl and half-fish. That, both biologically and dramatically, is just ridiculous. If the mermaid were half-fish, then why does she move her tail...
Suppose that a person has the ability to kill any living being it touches (literally). That happens due to the fact that when this person touches using such ability, the target's spot being touched...
Is there any way a catdog (like from the television program Catdog) could survive? If it could survive could it evolve? Are there any reasons it couldn't?
I'm currently brainstorming the rules for some Tolkien-esque elves. I'm trying to do some research to make them as realistic as possible, but all the science-y things go right over my head. I've pr...
Alternatively, could DNA be a language (the normal coding that exists within DNA to tell it what to build) that is capable of telling us anything. This question is based off of this article about...
Here I will talk about the digestive system of my Kepler Bb humanoids. Mouth The teeth are much stronger than bone(Strong enough that they can eat bones no problem). Other than that and all time ...

Age varies vastly even in just the vertebrate world, from the 2 years a rabbit has to the over 170 year old Seychelles giant tortoise, who is still going. Obviously, Lifespan will determine populat...
On my fictitious planet, a 1/2 pound mammal had a brain to body mass ratio similar to that of a human , could they have human - level intelligence, or would the brain be too small the develop that ...
Caloric intake varies vastly even in just the world of mammals, from the hundreds of pounds of leaves an elephant eats everyday, to the small amount a sloth eats. Obviously, caloric intake is impor...
A mutated species of hominid now grows up very quickly (perhaps 3x its normal growth rate) has a natural regeneration factor. Like an axolotl*, it can regrow complex structures that it loses, like ...
Litter size varies vastly even in just the world of mammals, from the single spawn of an elephant to the up to 30 children an opossum can have. Obvious, litter size will determine population, cultu...
In the award winning Studio Ghibli film, Arrietty, there exists a creature known simply as the Borrower. Borrowers are a small version of human, no taller than a few inches, yet are otherwise the s...
Vertebrate tooth enamel is made from Hydroxylapatite, however this need not be the only material available that an alien species could use to make teeth or tooth-like structures. Given that an ide...

In a species I am designing, they have eyesight similar to a cats, their vision at a distance is excellent, but the closer you get, the blurrier the vision is. One solution I had for this was for t...
In the never ending quest to get elves to live in trees, I am taking things one step further and attempting to get the entire city in a tree. Magic is not in the equation. The tree would start out ...
Positing a high (c. 35%) Oâ‚‚-level on a roughly Earth-equivalent planet (atmosphere about like the early Carboniferous), what types of lifeforms would flourish? Obviously, giant insects could be ...
For any reason, a human heart is replaced with a pump that instead of pulses provides a continuous stream of blood. It varies the pressure, as a heart does, as needed. Ignore such technical issues...
The idea of a collective consciousness (Or Anthill) is pretty simple: instead of cells you have small sentient animal that make up a larger creature. This is different from a hive mind in that the ...
Given any kind of living organism (plant, animal, silicate, gaseous, energy, etc.,) what logical reasons (natural, environmental, evolutionary selection, nurtured, artificial) could result in more ...
I'm trying to create a habitable planet but with a low atmospheric pressure, similar to Mars. But instead with 15 percent of Earth's atmospheric pressure, what traits can I give my animals so they ...

In my fictional world there are small organisms the size of a dog or smaller,some have the shape of mini-volcanoes, while some are stuck between rocks, they don't move and live in both sea and land...
Some people created synthetic bacterial life forms to use them as fuel producers back then; it's called synthia I believe... and I don't know how it ended up. So creating life is already possible...
If a tribe of homo evolves into a wild animal that doesn't resemble at all a hominid, is there any chance for this animal to evolve back to the original humanoid shape through atavism/other means? ...
Here's the scenario: animals on a world with an atmosphere with a significant amount of a certain gas is able to store "air" into a transparent growth (like a crest) and, with an electrical chord i...

Why would an non-Eusocial animal have a caste of sterile individuals? Formicidae and Apoidea have sterile workers,but those outnumber the fertile drones and princesses or queens. In another anima...
If your blood pressure ever falls below the ambient atmospheric pressure would it be possible for you to bleed. Because if blood pressure was less than that of atmosphere air would move in if you g...

Could a planet with an atmosphere composed mostly of neon, with oxygen and carbon dioxide making most of the rest, support life as we know it (specifically on a low gravity planet)? If so, what imp...

I'm currently working on a story treatment for a monster story. The story is sort of a love letter to many different genres and classic tropes employed and made famous by, John Carpenter, Ridley Sc...
I designed a humanoid race with bio-electric organs along the arms which release electricity through the hand to the victims (it has to be done in direct contact). The electricity released has to ...
On Earth, the vast majority of the biosphere is ultimately dependent on a large number of autotrophic organisms that produce usable energy in the form of glucose by using photosynthesis. However, o...
