What marine or brackish water animals would be best for domestication attempts by a semi-aquatic civilization? Bonus Points for those that get me pet/domesticated sharks!
In my story there will be animals that are incredibly strong and resistant to injury. To better understand how to design my creatures, I'm asking for help understanding how to make the Eurasian Br...
In a Galaxy where there are numerous Earth Like worlds, and FTL Travel is possible but only by a small number of species, possibly only by Humans, perhaps they just happened to get there first. In ...
Laugh all you like, you won't be laughing when it sprays you with its jade trunk of death. Info I figured out that I wanted an elephant that sprays poison (not acid) out of its trunk a while ago ...
So, out in Kansas, in the DEC Oil Refinery, a group of people, called simply the Disciples, have set up a community. From the outside, it seems like a utopia, one where man and mutant get along pea...
I have a small planet with a Radius of 3,900 kilometers and a density of 8.9 g/cc. It has an extremely Earth-like climate and has been extremely volcanically and geologically active in the "recent"...
I am a vengeful scientist who crash-landed on your Earth. While I was repairing my space ship, I had to obtain nourishment by consuming organic matter, and visited a local nutrition warehouse your ...
A habitable planet with multiple moons, only one of which is tidally locked to the planet: is this general scenario possible? I understand that tidal locking takes a very long time to happen. So ...

My question has to do with living inside a spaceship, which is mostly made up of a force field containing a breathable, earthlike atmosphere. There is a constant outward pull of something like 0.3 ...
Quick Context Basically I need one of my charaters to produce a lot of chlorine trifluoride, but human biochemistry wont allow that, so I was going to get a micro-organism to do the job and produc...
I'm trying to create a world where there's an equator-like divide running along the axis(?) of the planet and the two hemispheres are perpetually different in terms of temperature. Basically, I wan...
Premise Suppose a world has no other means to deal with a potentially devastating meteor impact than creating a net on the planet. Their hope is that the massive net will catch the meteor and slow...
I'm writing a short story that takes place on an imaginary planet that is 88% ocean. The planet has two moons and one continent that is regularly flooded under 500 to 1500 feet of water. The tides ...
If you were tasking with creating a genetically engineered flying creature, capable of full powered flight on a (newly terraformed) planet with a surface gravity almost twice that of Earth's, do yo...
So, it turns out that bats are actually pretty good swimmers; several species of bats have been reported swimming, and they're far more capable and agile in the water than they are on land: https:...
How plausible are naturally-evolved, biological, fixed-wing flying creatures? Could such a creature plausibly evolve in Earth-like conditions? If so, what method would it be most likely to use fo...
The origin of Superman is fairly well known. A baby is sent to a planet and gains super powers from being in the environment (technically the sun, but I believe you catch the gist). I'd like to mak...

As far as I have been able to determine, the majority of life reuses the same plumbing for reproductive and digestive/excretory systems. In fact, the anus is believed to be derived from the male go...
From my understanding, many of the features of water that make it very important for Earth's ecosystem are a result of oxygen's high electronegativity, which results in hydrogen bonding. As nitrog...
The current worldbuilding project I have is going to be detailed - very detailed. It's about the life of an alien planet called Nemo 4, and I want to chronicle the evolutionary history of that lif...
Trying to create a future earth which has been thoroughly abused by the excesses of modern capitalism. Extreme weather, rising sea levels, massive droughts, that sort of stuff. My question is: c...
Info I'm designing a breed of cow that produces acid instead of milk. Part of the reason this is useful for my story is that the cows produce as much acid as a dairy cow would milk (through selec...
