Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

Hi! I am new here! I am 13 years old (As you can tell from my username) but I love to make up creatures so I decided to join this site. However don't expect this to be scientifically correct because I don't know everything you guys do and I can't draw for my life so I will post descriptions instead. Anyway heres some info on my made up planet.

The world is 85% percent water and 15% land. The planet is roughly 90% the size of earth so the planets gravity is slightly less. The planet is slightly closer to its yellow dwarf sun so its ice caps are much smaller than earths. The land masses are mostly islands with one huge continent about 1 and a half times the size of north america. the continent has rivers going throughout the continent so most of the continent is forests, jungles and slightly farther away from the rivers, grasslands. The life here ranges from bizarre to bizarreo. A human colony has recently been established here...

Life coming soon!

Suggestions for the animals plants and even the planet will be appreciated very much! ^_^

Okay. . .what kind of star does it orbit?

In the end, the best advice I could give you would be to do your project in a way that feels natural to you, rather than trying to imitate some geek with a laptop in Colorado.

Hey!
When you say 5 times bigger than earth you mean volume or radius??

With 5 times the volume and 0,85g, the planet would need a density arround 2,6Kg/dm3 which is possible to water planets, but water planets don't have islands on its surface, well just if they're were floating islands..

5 times the earth's diameter would need a dencity less than water which I think that is impossible, keeping it in the 0,85g...

Cool you had started that early thinking in make a planet I was just 9 when I started but didn't minded with make it as real as possible :P

Thanks for the nice comment! I kinda forget the definitions of volume and radius so could you please explain them to me... Also here is a preview of one of the creatures called volt rodent.

Are you plausible?

I would imagine, since the 10% surface area of landmass consists of islands the size of Australia that a) they are mostly rainshadowed desert and b) there aren't too many separate landmasses.

Also, if the planet is 5 times as large as Earth but has around 85% surface gravity, the planet must not be very dense at all. How does this happen? Is the planet truly mostly water, and a great deal is subducted into the magma? Or is there some other chemical oddity at work?
Take a look at my exobiology subforum of the planet Nereus!

Hmm I guess the planet dosen't make sense. I am going to change the size of the planet and some other things about it... I'll Pm you when Im done

Saturn is less dense than water. In fact, with enough water, you could terraform Saturn itself by covering it with water from comets and build an artificial Pangaea. You would need some sort of inertial field though if you were going to combat the planet's gravity.

That would be beneficial in many ways as it would provide land area far larger than Earth itself, have vast amounts of water at your disposal, and you could harvest energy by mining the hydrogen from Saturn's atmosphere with big floating rigs.
We should all aspire to die surrounded by our dearest friends. Just like Julius Caesar.

"The Lord Universe said: 'The same fate I have given to all things from stones to stars, that one day they shall become naught but memories aloft upon the winds of time. From dust all was born, and to dust all shall return.' He then looked upon His greatest creation, life, and pitied them, for unlike stars and stones they would soon learn of this fate and despair in the futility of their own existence. And so the Lord Universe decided to give life two gifts to save them from this despair. The first of these gifts was the soul, that life might more readily accept their fate, and the second was fear, that they might in time learn to avoid it altogether." - Excerpt from a Chanagwan creation myth, Legends and Folklore of the Planet Ghar, collected and published by Yieju Bai'an, explorer from the Celestial Commonwealth of Qonming
