In my fantasy setting, cyclopses are large (about the size of a rhinocerus), carnivorous humanoids. They have a single blunt horn on their forehead, which is their primary tool for taking down prey...
So, let's suppose I finally made it. A creature that's very agile, able to resist most small-arms fire and has a whale-oil breath weapon. Flight is solved with bones, as strong as carbon fiber, (la...
I'm considering a scenario where Humans cannot live on Earth anymore, and need to settle other planets. Some physicist I follow on YouTube like to remind us that almost no mater what we do to Earth...
Suppose we knew of an extinction level event in a few decades, and through a large Manhattan Project-type effort humanity manages to construct a von Neumann probe with a copy of all human knowledge...
A colony ship headed for its new home countless light-years from Earth suffers an unfortunate malfunction on the final part of its descent phase and crashes onto the planet. Thankfully, the ship cr...
For a certain reason, I needed two habitable similar earth-like planets very close to each other. After various information gathering, I gave up on double planet and gas giant moons, because tidal ...
In my story, I have two late renaissance era cultures discovering each other for the first time and I plan for the story to develop into more of how they both understand each other. However, I don'...
One morning, as Gregor Samsa was waking up from anxious dreams, he discovered that in bed he had been changed into Legosi from Beastars. He felt a dull pain a bit above his behind, as he li...
In the story I'm making, it is important that there are two suns in the sky, going at different rythms (maybe the planet orbits one of them each year, and the other each four years, for instance), ...
Basic scenario: An abundance of a simple Lipid is introduced to a large body of liquid (water for simplicity), there's some motion; wind or gravity or whatever, and the Lipids bump into one another...
So, two nations are in a war, land is off-topic as it's filled with zombies and necromancer zombies. The other logical option is the sea. Now, one nation has these creatures, called wyverns. Wyve...
I was thinking of a situation, in which there is a mass extinction that wipes out all large land animals, and after this mass extinction some of the descendants of modern geckos evolve to fill the ...
I'm developing a story where humans colonize a few planets. One planet, lets call it Planet A, has similar gravity to earth, air pressure, and solar radiation. You cannot however, walk on the surf...
In my world, there are 3 astrological bodies of significance, the sun, the moon, and a 3rd, geostationary object, believed to be the home of the gods. I want all three of them to have roughly the s...
This is something I'm struggling to find answers for online. I need to be able to explain and justify the biology of a species that capable of surving in multiple environments including changes in ...
The planet is 10 Earth-Radii, with a 1 Earth Gravity value. It is a habitable planet. It has a thin atmosphere. It also has 3 moons and a ring system. The moons are rather large. The largest one i...
An old saying goes that if you have an army, it will want to fight a war. That seems to be true also for our personal army, our immune system: there seems to be various pieces of evidence that man...
I am writing a story, in which a mad scientist (based on Ted Kaczynski) wants to kill as many people as possible with an artificially created disease. The idea is, that more complex societies are ...
I am a complete amateur regarding biology, so please forgive me if this question is a little stupid. Could we ever create squids that have human-level intelligence and could serve as a replacement ...
I'm working with this alien race that looks and functions essentially like a mammal - skin, muscles, hair, internal bones, large size, etc. - but evolved from an insect or other bug. They're a larg...
Let's talk about dragons for a bit. Giant, flying, deadly predators with teeth and claws and fire and scales. Unfortunately, "giant" and "flying" don't play together nicely in physics' playground. ...
I had an idea for a new world that included cactus forests, with cactuses the size of a giant sequoia. Is this realistic?
How do steampunk civilizations get lifting gas? What you want is "Synthesis gas". It's what all good fellows with a hunger for flight and adventure need. How shall I make this gas you ask? Wel...
Some plants and animals would focus on the borderlands. While regular shade could exist anywhere, mountains and other large geology would give the deepest shade, enough to change the climate. The ...
The biggest problem with spacecraft is weight. You want things to weigh less and less. So, your halflings have a natural advantage in spaceflight. This means that, while it seems you are fighting ...
