I know a tadpole can do this transformation, given enough time, so what about mermaids?
I want a mermaid protagonist. If I am to make this story realistic, how should the Merfolk's body structures be made to make them adaptable for both water (swimming) and land (walking, running)? Is...
I'm referring to an entomological plastron which is a structure that traps a bubble of air next to the insect's body but permits contact between the air and the water. As the insect consumes oxygen...
Many planets out there will be water worlds. Those generally come in two flavors: either the oceans are so deep that the water turns into high-pressure ices like ice-six, -seven, -ten and -eleven o...
Based on the planet from this question. The main thing that distinguishes this planet from, say, Europa, is the handwavium light-source, which I must assume is wrapped in a perpetual explosion wrap...
If we assume a terraformed Ganymede has a global ocean roughly 800km deep, that food is bountiful, and that it has been populated by a variety of life from Earth, how large could these creatures gr...
Landia, a land based civilisation, has recently established diplomatic relations with Aquatica, a civilisation of fish people. The two peoples exchange gifts to each other - including from Landia, ...
It's easy to imagine how would a water-breathing aquatic race outfit its spaceship - take a normal spaceship, insulate it, fill it with oxygenated water, possibly add some enhanced turbines to pump...
While reading this question about how non-primate mammals could develop a bipedal stance, I became curious about the broader reasons why animals could evolve to walk on two legs. I found some insi...
Imagine that when Christopher Columbus sailed West in his Carrack to travel around the world to reach India, he had never made it to land, because halfway across the Atlantic Ocean between Europe a...
Hopefully this isn't two separate questions - I do feel like they are interconnected enough that they can be counted as one. I'm wondering if it would be possible for primitive human ancestors. Le...
A radical shift in the Earth's orbit has made the Earth much colder, with all the oceans freezing over, and the atmosphere liquifying and falling as rain. Humans live deep underground in areas of h...
This is strictly Earth based. Would it be possible for a society to develop their own civilization underwater (nothing fantastical like Aquaman or whatever, but more of a grimy, hardscrabble existe...
Assuming the same rules for physics apply to this world as they do for our own, how would a humanoid race that lives at the bottom of the sea be able to walk around like humans do on land? What kin...
I'm trying to create basically realistic mermaids, and working on developing body language and vocalizations. I have most of the vocalizations I can think of (suggestions are still appreciated), bu...
It makes sense to me that the best food in an underwater dome complex would be fish. Considering the massive amounts of aquatic life in the vicinity, it could work pretty well. However, I can't th...
Suppose that there was a tribe of nomadic mermaids whose lives were primarily centered around following pods of dolphins to eat. They live in the equivalent of the frigid antarctic seas. As they ...
I was thinking of an alternate history, in a part of a civilization, living along the Eastern Mediterranean, during the Bronze Age moves to the sea floor to found an underwater civilization. They ...
I'm interested in creating some construct of a society in the Twilight and Midnight zones of the ocean. By what means could they mine, farm, and trade in what is suppose to be a more futuristic so...
I want to put a story in place where a country lived underwater, and I am wondering of its viability. Here is the world description: It is a square of 100 km*100 km on the ocean with the weather ...
I'm writing a story that takes place entirely underwater, mostly in a deep sea town and shallower city. Both are underwater and populated by beings who can survive underwater. My thinking is that...
In a vaguely Medieval setting with some limited magic, how would an underwater city handle sewage? Sanitation was one of the biggest limiting factors in the growth of human cities, and being under...
I don't wanna reveal too much about my world, however, the basic idea is that there is a town of people who live deep underwater (they are biologically capable of doing underwater gas exchange and ...
A soft and vulnerable intelligent underwater species, you can consider them closely related to Earth's octopus - in the way chimps are closely related to humans. Consider that clothing is often wo...
With the rise of global warming and our leaders not seeming to do enough about it, expanding our ranges past the earth's ground seems like something we must do eventually. Everyone always points to...
I have followed this forum for quite some time. Now is the time to ask my first question :) I'm currently working on a story in which a future, civilian luxury submarine is used to research some li...
I want to achieve the following. Jet + secret base underwater + blow up water with bomb to gain entry to tunnel at bottom of the sea, see image: Say that the depth is 1000m, then Based on calcul...
In a post-post-apocalyptic world with adequately schizophrenic tech, a tinkerer decides to build a submarine engine around a lump of radium, or some other reliable source of heat. But instead of us...
I'm currently trying to set up an underwater race in my world"”merpeople if you will"”and I'm trying to figure out how their city would look. I'm basing their religion and lifestyle on native civil...
My mermaids have returned, and now they're dragging semi-conscious people about 700-ish meters underwater. Is it realistic for the person to still be alive at this point? (Y'know, for about ten sec...
So, in my story, in a prelude to an epic aquatic fight scene, my main character gets chased by a great white shark. He swims as fast as he can but he can't escape. Just to clarify, he's wearing one...
Humans lay road to gain fast access to distant places until aeroplane is invented, I would presume the mermaids living underwater can make use of the strong water current to get around the ocean qu...
Right now merfolks are totally envious of us watching a live stream video of cat(fight) via WiFi or satellite internet, ok ok I get it's not the speed but its latency... Urrrr. Nevermind that I sin...
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...
Let's use the sea turtle and the terrapin as an example, need I say more? I used terrapin because like the mermaid which is half fish and half girl so a terrapin would serve as an excellent example...
I must admit this legendary or mythical creature is really fascinating and I am talking about the half fish half woman. I know most fish have the ability to control buoyancy as they can easily mov...
I have a race of octopodes with the same intelligence distribution as humans. I want them to "colonise" land to a similar extent as we have "colonised" space; have regular transport between the oce...
I've got a species that lives in the Southern Ocean along the Antarctic coast, and they are basically a sentient crossbreed of Orca whales and elephant seals. They are omnivores, have opposeable th...
My story takes place hundreds of years in the future after global warming has made life at the surface uninhabitable for most life forms. What's left of mankind survived because it became popular t...
First of all, I tried to look if this wasn't answered before. Found this and this but neither is exactly what I need. Some Context There's this race of humanoid fish people. They live in cities b...
You have an underwater civilisation, be they merpeople, octopus people, partially evolved humans or not. One thing that is always considered as a necessity in the development of any society is mini...
Looking to how I can make Nagas and Mermaids able to exist and evolve in my story, I came across this post which explains how Nagas could evolve from humans: Anatomically Correct Naga In the top a...
In my colonizing business, some colonists build a underwater base on a all-about nice planet. They are using food storage right now; but now they need to start farming. Ive looked up some farming t...
In my book series, a space station called the T-Ray that is capable of causing explosions the size of the Chixculub impact explosion just fired at a planet that is completely covered by a massive o...
Reading questions of How much TNT needed to blow up Mount Everest and the Moon - and especially the comments below it, I have to ask it: Can we blow up the sea? Detonating atomic bomb undersea ma...
In a world I'm currently developing, I'm working on a merpeople equivalent (more or less physically identical to your bogstandard mermaids, for the purposes of this question), and I want them to we...
Let's pretend these magnificent and beautiful creatures are able to reproduce asexually so we can forget about their mating habits or their partners. I have yet to witness any hard shell eggs laid...
In the world I'm building, there is a single continent. However, in the deeper parts of the ocean, there are hydrothermal vents. They're pretty necessary to my story, but I can't figure out why the...
In my fantasy world, there has been a longstanding presence of underwater civilizations, both alongside and independent of surface-based kingdoms. In the style of Tolkien's Beleriand, various conti...
I rediscovered this article recently and loved all the creative answers on how a mermaid might build underwater. This, for me, brought to mind Atlantis, the kingdom that sank into the sea. I've...
