The Apex predator of the Sea of Grass biome from planet Andromeda is mostly bipedal, but capable of facultative quadrupedalism, it has long limbs, powerful claws on its hands and is roughly the siz...
What possible evolutionary adaptations could you foresee in the sensory organs of wildlife in an environment beset by a nigh-permanent sandstorm? e.g. in the case of vision, ways to protect the ey...
Postpartum depression among humans is a thing that is "normal" insofar as it happens a lot, but it is not "normal" in the sense of "a thing that we don't worry about"; it doesn't happen to absolute...

Is there a way for a species to essentially become a living incubator of sorts? Not the other way around, as in Plausible ways for the alien species to be able to impregnate every and any species?,...
In the large pillar forests of planet x, a group of vertebrates, in order to hunt down the fast climbing creatures that inhabit their habitat, rather than developing speed as well, went on another ...
I understand that one does not simply scale up the smallest of creatures to the size of megafauna without violating basic physiological constraints like the square/cube law, among others; so what w...
Imagine a species of humanoid beings living on an Earth-like planet somewhere in the universe; they have developed complex spoken and written languages and they can study their own anatomy and the ...
I've read super-earths might become archipelago planets. Picture shallow seas, under a thick atmosphere that alternates between muggy and clammy. Because a bigger share of the surface would be cont...
I'm Wyvera, a young female writer. I've been working on a science fiction project for more than a year now. This project, which I will eventually turn into a novel series, is supposed to remain as ...
Extremely low possibility, but if life synthesizes from scratch after life has existed on a planet for a few million years, would the two separate lineages be able to co-exist?
Wait ... what? Basically, this: Most land predators on Earth use their mouths to kill their prey. That is, they have to stick their precious, irreplaceable heads into harm's way every time they ...
A sentient species of water-dwelling aliens achieve space-flight. Their living quarters contain water [no free gases]. They have evolved over millions of years to regulate their buoyancy at will...
If an extraterrestrial race were to send a signal to earth containing a virus (technological or psychological), how could that signal then infect our technology and then be received by humans?
I have some alien creatures which are essentially land-going octopoids somewhat larger than humans. Tentacles not being a good form of propulsion on land, they have rudimentary 'legs' with one bone...
In my story, there is a planet that experiences near constant sunlight. Since sunlight so plentiful and reliable most organisms are, at least in part, photosynthetic. The only intelligent life on ...
As a thought project, I wanted to make an alien species that eats without any use of the tongue, but I've run into the problem that it's almost impossible to swallow solids without choking without ...
I want to write a science-based story which includes grey aliens. To clarify, grey aliens are seen to be either shorter or taller than the average humans, and sport a bulbous like head. their hea...
I'm trying to create a scenario where the local star is "quickly" (suddenly up to thousands of years) removed, dimmed with reduced output, destroyed (maybe), or otherwise fundamentally changed as t...
Mankind has been always interested in making contact with another (extraterrestrial) civilization. We have launched the Pioneer 10 and 11 probes with plaques explaining where the Earth is located. ...
Disclaimer: This question uses some liberal wording to get key ideas across. It's not meant to be academically rigorous, so please try to focus on the ideas and not the exact definitions of the ter...
Is it simply inevitable that on a planet organisms would split into motile and non-motile groups. I'm planning on creating slime-like amoebic chemotrophs for my light devoid-planet that are the "pl...
Imagine a visiting alien accidentally spilled a bucket of inverse matter (a substance I made up just now) on the planet Earth and this stuff will annihilate with ordinary matter to produce neutrino...
The Aargh are a humanoid alien race a couple solar systems away. Their home planet is quite earth-like (oxygen atmosphere, a lot of water, traditional organic chemistry even if a few proteins are d...
We all know that the universe is going to die one day: all the stars will die, all the black holes will evaporate and life will be gone. But hypothetically speaking, if a super advanced alien race ...
I'm thinking about designing an alien race. The race is carbon-based and evolved on a world with an average surface temperature between 40 and 60 degrees Celsius. Now, on Earth, almost all lifeform...
Summary at bottom. I have a character from a homemade alien species. The species has silver/white hair and blue/violet eyes. I know these are traits of a melanin deficiency, but I imagined her hav...
I'm writing a story where aliens are using humanity like a botnet to do hyper complex calculations - each infested human has a program running in their subconscious brain that does a small part of ...
This is a follow up question to my previous question: Rock/Mineral Ore Eating Organism So these things: https://en.wikipedia.org/wiki/Lithoredo They eat limestone. So I thought, what is limestone...
I'm basically searching for an ATP that can be used to supply cells and also have its energy extracted efficiently into a basic form of explosive material (the stronger the better) without a lot of...
Real-life octopi can travel outside of water for awhile, but not permanently. My race is amphibious, living underwater primarily, but also coming up onto the surface if their environment becomes to...
How would an alien organism survive on a diet of rocks and mineral ores, and what kind of materials would be the most sufficient? Also, what kind of teeth and evolutionary traits would they possess...
The aliens in question aren't of a hive mind in the strictest sense (instead of many drones answering to a leadership caste each organism acts as one cell, all of them are essentially 'the same ran...
Let's say there is a planet orbiting a star. The planet is much like our own, with a similar atmosphere. However, the star this planet orbits differ from out star. It differs in such a way that it ...
I was reading this question, and it made me wonder if something like this is possible or not. So, the question is, Is it possible to have an alien species in whom, the newborns are bigger than adu...
Let's say that the aliens exist, do you think that they are smart enough to create their own Mathematics? Or even their own Sciences?
Assume that you have a Rogue Planet hurtling through deep space. Somehow, an alien civilization from, say, 1,000 ly away acquires astronomical data from this planet. This data is in the form of h...
I'm working on a sci fi story where one of the species has batlike wings and comes from a moon around the size of Titan with roughly the same atmospheric pressure as Earth. Initially, I thought the...
This question about eating on a alien world got me thinking.... Would it be easier for humans to colonise a world with existing life, or one which was biologically dead? For the living world, let...
Rules: No magic Eat, drink, and breathe air (mammal/reptile(amphibian ok)) Intelligent life form (no jellyfish or single-celled organisms) No artificial hearts (unless really ingenious, no swappi...
It's around the mid-2300s. Earth is, to put it simply, in trouble. Climate change has resulted in flooding of major coastal cities, displacing billions, which ultimately led to widespread conflict ...
I am developing an alien race whose homeworld is a Dyson sphere planetoid (they used collected planetary and asteroid matter to construct a "hollow planet" around their sun, along with "night" sola...
TL;DR: I want a society which behaves as a hive. Is it plausible and how to achieve this? The setup: Different planet in our universe. In other words: Normal, physical rules apply, there is no mag...
I have a (digitigrade) quadrupedal alien creature with one of it's front limbs having a longer metatarsals, I'm trying to visualise how it would walk with this deformity for an animation. I'm havi...
