I've been looking at the altitude boosted SSTO designs from the 90s that were designed to be lifted to launch altitude by modified jetliners and thinking about bumblebees and wondering if bioships ...
I'm creating a large ungulate that is likely a part of the suborder Anclyopoda. Suspension of disbelief is expected, but there's a detail with the current design that's really bugging me. The cre...
I need to add a bit of descriptive detail on a species from a brief description. Essentially add a bit of finer detail to someone else's broad-strokes worldbuilding. An amphibious species' body lay...
In my worldbuilding project, 2 continents located on roughly the same latitude are connected by a land bridge. Both sides of the bridge are surrounded by a temperate grassland, and the lack of seas...
As far as I could gather the digestion relies on enzymes which in turn set requirements for pH. Is it possible for an alien creature to have a different set of enzymes that require basic environme...
So I want to have an alien creature on a planet with a halogen atmosphere. It will have to be at a temperature where the hydrogen halide is liquid or solid. This hydrogen halide I would have as th...
So, I have thought about the evolution of my aliens and how they could evolve things like lactation but still retain their reptilian characteristics. Here is my best thought about it so far: Evol...
This is a classic of fantasy/sci-fi stories. A creature with two heads, two brains, two distinct personalities, sharing a single body. An entire race of Siamese twins. But the question is, what env...
I am trying to create an organism that can survive in space for short periods, but I realized that I can't have its eyes be similar to those of most animals and humans because they would boil in sp...
For a space-based story I am writing, I was hypothesising about how to have organisms that can thrive the vacuum of space. Ignoring plausibility of such a creature evolving, I realised a few probl...
For an elf-like race whose people do not age beyond physical maturity (the accumulated DNA damage associated with aging does not occur), what would prevent overpopulation? This elf-like race is f...
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...
I am wondering what kind of physical qualities (E.g. Short, thick pillar-like legs) a creature such as this would need to support such an incredible size. The world that it evolves on in almost ide...
How could trees in an environment with 23% Oxygen (The atmosphere is identical to earth in all other respects.) grow bark with Starlite-like qualities? Starlite is a material claimed to be abl...
As the title says, you know stuff like minotaur, lycanth or werewolf, cat or dog folk, etc especially for the female specimens. I want to know what happen if quadrupedal mammals which usually have...
What sort of fireproof liquid could be used by carbon-based life without causing harm to the organism? Whether it be absorbed from exterior sources or produced in the organism's body. I say organis...
I am working on a world which is very dark due to an opaque gas layer in the hight atmosphere; but it is opaque mostly in the terahertz range. The creatures in this world therefore rely very little...
I am designing a creature that is quadrupedal but can run after prey on its hind legs. What kind of hip bone would allow for the excess stress to be put on it during bipedal locomotion? The animal ...
Could a creature be made entirely, or mostly of magma or lava? Could it sustainably live in or near a volcano for an extended period of time? Rocks around the outside are optional, and encouraged. ...
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...
Larry Niven's "Known Universe" (KU) features "The Outsiders" as one of its most prominent alien races. As per KU canon, the Outsiders evolved in a frigid moon (similar to Nereida) and they sustai...
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 ...
I had an idea of a concept a while ago. If a planet that for some reason or another had only one giant continent like Pangea, but bigger, for more distinct habitats and giant lakes assuring isola...
In Invertebrates, Muscular Hydrostat, which is a form of biological hydraulic, is used for locomotion. On Earth, (as far as I'm aware) no system exists where hydraulics perform in conjunction with ...
I've designed an alien race of bipedal humanoids with digitigrade legs. This race's advanced scientific progress means that they use traditionally human-associated technology, or similar (such as ...
My alien race is supposed to have the ability to communicate a lot of information extremely fast, more akin to uploading something to your partner's mind than telling him. This should happen via si...
What other kind of mouthparts might an alien (intelligent or non-intelligent) have besides the typical jaw with teeth or mandibles? To avoid being too broad a subject, let's assume the aliens need...
I wanted a creature that produces something in its blood to protect itself from SEP (solar energetic particles) and GCR (galactic cosmic rays). The skin of the creature is normally sufficient prote...
I've answered a few questions with this process but I wanted to see if I could bounce/refine this off the communities more biologically adept members. Basically, it goes like so: As a means o...
When they started dropping from the skies.. or no, they landed. They were so similar to us, yet so different. Like nothing we would've ever designed or created - but so much like everything Ey...
In this world, the vehicles are effectively re-engineered insects; enlarged bio-manufactured nervous systems used instead of engines; factory grown lightweight chassis / [wheels]. The fuel station ...
What factors would influence ecosystem development in an ocean on an ice world? It is thought that several moons in our solar system (e.g. Europa) may have significant oceans under their icy crust...
On Earth life has six fundamental building blocks for life with them being Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus, and Sulfur. (1) Those elements of help make up more complex life through a...
***** Xenobiology expedition 'Profundity': Log entry 504 ***** Glass Ants are a fascinating species. We discovered them on an arid desert world last visited by humanity aeons ago. They seem to h...
Take a planet like Gliese 1214 B, which has no land, an ocean 100s of kilometres deep and a seabed of Ice VII. For the purposes of the question, let's assume that the pressure and/or temperature ne...
...kill every protohuman who tries to leave the African continent. This comment made me think about one question. Suppose you have robot guards, like futuristic lasers, who just shoot at any ...
My winged people just have feathers on their wings, and maybe small feathers on their back between their wings (from shoulder blades to mid back). Their bodies look generally human. Here is a lin...
Whales and dolphins surely do not have ears similar to ours and yet they can pick up ultrasound underwater without fear of water pressure damaging the eardrum. Any idea how the mermaids with ears l...
TL;DR - I want my angelic race to have the ability to speak in a way in which up to three sentences are communicated at the same time. (Assume English for the sake of simplicity. I want physiolo...
My story has a race exactly like humans, except they grow to be on average 9 feet tall. One of characters belongs to this race, but she is considered a dwarf to her people. This causes her to live ...
Premise and research I am simply trying to find a reproducible framework for use with creature-design. In my research I have found the larger an animal is, the more likely that animal is to break ...
A creature in my story was largely inspired by the xenomorphs of the Alien franchise. In wondering how long it would take one of these creatures to grow from conception to maturity, I decided to lo...
Say if a planet had either no greenhouse gases or a small percentage of a certain greenhouse gas (roughly 5% or less) in its atmosphere, but all other elements in the atmosphere could support life....
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...
Well, I have been having computer problems and I decided that now is as good a time as ever to continue to waste my time developing my reptilian, honor-obsessed militaristic race of lizards for a p...
What conditions might make a planet more likely to develop silion based life, the factors I need to kmow are listed below Temperature of the planet The solvent that they can use in their biology ...
The Eldar are a psychic species with a similar body design to humanity within a galaxy-wide empire. They are far more advanced than other races, technologically and philosophically. Eldar have a st...
As seen on others questions biological radio could be a thing. How to evolve biological radios? What would a species require to be able to inherently transmit and receive radio waves? I was inte...
Setup: A planet generally with an earthlike climate, although slightly wetter and warmer as a general rule, with a little more oxygen in the atmosphere, but habitable by unmodified humans. Still h...
