On Earth, all plants are green because they contain the pigment chlorophyll, which photosynthesizes by absorbing all light except green light. However, it is quite possible - if not likely - that ...
Earth's atmosphere, as you probably know, is divided into five layers - the troposphere, stratosphere, mesosphere, thermosphere and exosphere. https://en.wikipedia.org/wiki/Atmosphere_of_Earth#Str...
During much of the Late Pleistocene stage, the world's most widespread biome was the so-called "mammoth steppe" - a cold, dry grassland which spanned eastward all the way from Spain to Canada. It w...
I had an idea for a planet which has very hot days, roughly 40 degrees C on average, and very cold nights, average -5 degrees. These figures are subject to change. Of course, there are places which...
Subarenaceous animals are those which can move long distances through dry sand - like sandfish lizards, or Dune's sandworms. The main problem they have to tackle is turning the sand immediately aro...
In the mythology of the Lambas people of Zambia, there is a creature called the Ichisonga. It is a herbivore, and very rhinoceros-like in appearance. Upon hearing a hippopotamus, it allegedly sne...
A cool thing to imagine would be a world where the land was dominated by megafaunal frog-descendants, as it is/was by mammals today, dinosaurs before the mammals, and non-mammalian synapsids and cr...
The dragons in my fantasy world spit fluid from their mouths when threatened, which upon contact causes a burning sensation. I could have this liquid be standard venom, like modified saliva, but I ...
Sonic weapons are frequently used by military circles as non-lethal irritants to deter opponents. My question is; could a naturally evolved organism kill, or at least incapacitate, small prey using...
This is the latest in a long series of questions I've asked on my fantasy world which contains many mythical and folkloric creatures. I won't link the other questions since at this stage the series...
James Cameron's Avatar featured floating mountains which stayed aloft due to the Meissner effect; they contained large quantities of the room-temperature superconductor unobtainium, which, due to t...
Would it be possible for huge, hundreds-of-metres-long spikes of rock, ideally slanting at an angle, to arise under natural processes? For clarity, I mean like this: Copyright Joe Jesus Ther...
So, I'm currently toying around with the idea of a hypercarnivorous sapient race on a planet in my universe, and I'd like to make them scary, but without abiding only by the "rule of cool". (Also n...
So, in my last question, I asked "How could an animal run fast using blade-like feet that sink into spongy ground?" The premise was that on my planet, forests grow not from soil but from spongy, ...
The 12 planets in my solar system orbit the G-type star of Nemo. It's about nine-tenths of the size of the sun, and has a stellar luminosity of 0.67 L☉, a diameter of 1.28 million kilometres, a s...
Lithotrophy is a phenomenon known from microscopic life, where an organism converts inorganic substances, usually minerals, into energy. So, we know that a single-celled life form can do this, but...
I've recently decided to revive an old project of mine involving an alien planet. Unfortunately, however, I was not as good a worldbuilder then as I am now, and that's having some consequences. Ba...
Note: an edit has been made to the main question at the bottom A couple of years ago, I had a worldbuilding project which I have recently revived. I was relatively new to worldbuilding back the...
In my last question, How large could my sea serpents be?, I asked what length would be a) possible and b) necessary for a whale-eating sea serpent. My sea serpent is a constricting predator* in a c...
EDIT: (Important) M. A. Golding commented that the regalecid method of locomotion would be unfit for a constricting predator, so I have completely redone the taxonomy of the sea serpent. They are n...
Edit: I've written an answer of my own now, and I'd appreciate it if any of you informed on the subject of evolution could review it, then inform me of its plausibility, via the comments (Of the a...
Note: this is not a duplicate of Anatomically correct Giants or What would be the tallest possible height for humanlike creatures in earthlike conditions? because my giants are far from humanoid. A...
This is the second question in a series about my ongoing worldbuilding project, which seeks to explain the evolution and biology of various fantasy creatures. The first one was: Is petrifying visi...
Note: this question is not a duplicate. The accepted answer to the question "Anatomically correct Medusa" explains the petrifying vision via calcifying toxins spat from the snake hair. This a) woul...
An integral species in a large worldbuilding project I'm working on right now is based around the concept of extreme agility. The species shall be a megafauna (Is that grammatically correct - "a m...
