So let's consider a species of blind, sea dwelling, squid-like aliens. They are sentient, intelligent and highly social. As their societies develop and their available knowledge increases they req...
First question! I'm excited to see if anyone can help me. Any missteps are unintentional, but feel free to tell me so that I may learn. So, I've recently started brainstorming over a possible st...
Let's say there is another planet in our solar system that harbours sentient life and this sentient life can build castles, buildings, and other such structures. When would we notice that? We ca...
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...
Far away, across the vastness of space, lies an alien civilization, who are pretty similar to us. They've got ice cream, peer to peer networking, and photography. More importantly, they do lots of ...
I am an aspiring science-fiction novelist. I am experimenting with a world I'm trying to create and I wanted a couple of expert opinions on Atmospheric composition; 53% Nitrogen 27% Oxygen 3% Xen...

In this answer https://worldbuilding.stackexchange.com/a/25219/50641 (to the attached question) one of their counter points was "oh, crows use tools, therefore, human advantage negated". That got ...
I'm designing an alien species, whose blood is highly acidic and can easily cause someone's hand to melt down. It's pretty similar to the Xenomorphs from Ridley Scott's Alien, except for the color ...
In my world an advanced alien civilization are worshiped as gods by the human population. As the gods have better things to do than actually spend time interacting with the local fauna they created...
I'm trying to create alien species that is hermaphroditic, with strong sexual conflict. In essence each being tries to trick or force (by mechanical or hormonal means) its partner to take role of f...
If a human is kidnapped by an alien vessel and taken to another planet - and, for the sake of argument, let's assume that the alien life-form lives in a completely different environment from Earth'...
Edit: I am asking in the context of alien life, should have specifyed that to begin with. I have many ideas for fantasy/sci fi races, and one that I kept coming back to is a species with bones th...
In Wayne Douglas Barlowe's classic book "Expedition" he has many strange creatures. One that intrigues the most is this one, the flipstick. It has two feet on either side and uses them to flip th...
Think of this alien life form as something resembling earth bats, placed in a planet with Earth-like conditions. Micro-bats have small and poorly developed eyes. Similarly, this alien species is ...
They do not necessarily meet humans and try to interact with them. This question is more about the technical possibility/impossibility of 4D aliens being able to "analyze" the inner structure of ou...
This is part of my Alien Message series: Recognizable natural numbers for alien message? Alien message: "Invitation" I recall a TV show featuring a discussion on the design of warning messages ...
I am a new person to this but I have been looking at similar questions about silicon life. I'm currently trying to create silicon-based lifeforms on a planet with a surface temperature of about, -...
In almost every sci fi alien trope there will be a directive whereby one of the general order states no spacecraft may interfere with the normal development of any alien life or society and is puni...
Researching for a science fiction novel. My character loves math + I have dyscalculia = Problem. Therefore, I need your help. In my story, there are aliens we can see, but we can't hear or touch. ...
As an ancient organism whom currently occupies a large chunk of a planet beneath the surface, I have a pesky issue with an invasive species. These humans have decided to colonize my home, mistaking...
I know of the conceptualized "Sinkers", "Floaters" and "Hunters" that Carl Sagan and Edwin Salpeter of Cornell conceived of - as possible life forms that might inhabit a gas giant. At the time they...
I am working out a future scenario in which humans begin to discover alien life; I want their discoveries to be plausible. For example, I've frequently heard that alien life will most likely be ca...
I've recently become interested in the possibility of silicon based life. Assume these creatures developed on a planet with zero carbon (don't question, just accept it), so they have no carbon in t...
I've already considered that they may file their horns down, but keeping in mind that their horns gradually regrow, it is an inconvenient solution. This is what their horns typically look like: ...
Ok, so, some quick background... I'm not an evolutionary biologist or anything, but I'm helping a friend with some alien design ideas, and at least one of them she designed and wanted help to someh...
Humanity, with modern science, has established that the Big Bang happened 13.8 billion years ago. The universe appeared in a low-entropy state, and for billions of years has been expanding and movi...
There are many tiny humanoids in fiction, the Arquilians of Men in Black, the Gargantians of Buzz Lightyear Star Command and a few others. This raises the question, is it possible for a humanoid sp...
Having recently studied Galileo theory on the Square-Cube Law, I was curiously thinking about how this would apply to alien life forms on another planet. I've come up with these theories and would ...
500,000 people have been kidnapped from all over the world by aliens. The aliens want to see if humans have empathy, and they can't understand our languages, as we speak they hear just random nois...
Let's assume that this hypothetical alien crawled out of the identical primordial ooze to the point where they share significant genetic similarity with humans, and due to either evolution or outsi...
As part of a story idea, I'd like to create an alien civilization that colonized different solar systems in a manner similar to how European nations colonized other continents here on Earth. This c...
Let us say that the humans, with our era of technology plus 5 to 10 years, are contacted by an intergalactic alien union. They want us to join them, and we gladly do. As it is common when several c...
So, in my story there is a species of aliens, called the Ko'dor. The Ko'dor are a species of shape-shifters, who can change their forms at will. Naturally, they are four-eyed, green octopus like cr...
So, humans have finally figured out how to build a solar-system crossing ship. On the way to the first exo-planet to be colonized, an accident happens, and a few people wind up floating through spa...
So aliens find Earth to be suitable for colonization and disregard humanity's claim. Not because they are racist, but because they are so different biologically and psychologically that humans simp...
On a world I am building, I have a species of creatures that evolved from crustaceans. The problem is that while they have an exoskeleton, they also live on a world with the same gravity as Earth. ...
What should conditions on an alien planet be like, if the aliens of said planet move 3 or 4 times slower on their home planet than they could if they were to come to Earth? (Gravity, atmosphere, et...
I was asking a deviantART.com artist why they often draw their anthros and furries with wide hips regardless of gender, and they told me this (copypasting): "I'll see if I can't whip something up ...
I'm playing around with a story idea that includes vacuum dwelling intelligent life, but I'm not sure I understand the constraints of biochemistry I need to deal with. There's lots of potential s...
In humans skin color varies slightly in shades of dark brown to a faded pink, which has the purpose of protecting the skin from sunlight. An idea used commonly by people beginning designing alien i...
Background: In my world, there are a number of species that stemmed from the 'original base' (humans) who traveled through space for years before a collapse in organized government crippled logist...
I just want big cat eyes (i.e., lions, tigers, etc.) in a humanoid that can be just as expressive as a human's yet not having our very conspicuous eye-whites. Doable, yes or no?
In the event that both planets of a binary planet system were life supporting, and both ended up developing a sapient, tool using species, at what technological level would they be able to start ef...
In my story there is a humanoid alien race, that looks almost exactly like humans, but as you might have guessed, are boneless. Just to be clear, I'm not interested in reasons why they would evolv...
In almost all science-fiction stories that include alien races, said aliens are similar to humans in many ways: bipedal (and often humanoid), communicate with sounds coming out of a mouth, orient i...
Specifically, arthropod eyes that are neatly in their respective sockets, much like the human eyes. Could that work?
Would a Dyson sphere make a red dwarf appear to be a Brown Dwarf? Would it disguise a star enough to misidentify it what size it is? I'm just wondering if it could be possible that some Dyson sph...
I'm designing an alien race that in structure to humans. One exception is that they have long muscular tails. I remembered while I was designing them, the reason why humans have no tails is becau...
I've been thinking, could there possibly be an organism that is based on the element of helium? If yes, what would it look like? (Images are welcome)
