This is part of my new undertaking I'm calling "Expedition Freyja". The basic goal is to create a planet with a biosphere and fill it with life. I plan on being as scientific as possible concerning the probability of these creatures existing. The creatures will be described as if they had been discovered and studied by humans, complete with scientific names, height, length, weight, habitat(shown on small map), behavior, and diet. Also included will be a short summary on what inspired me to create the creature.

FREYJA
Planet Info
Air: Nitrogen 54%, Oxygen 30%, Carbon Dioxide 14%, 2% (helium, hydrogen sulfide, methane, and water vapor)
Diameter: 6130 miles (0.77 earth)
Mass: 0.70 earth
Gravity: 0.75 earth
Day: 26 earth hours (though because of the 2 suns, night isn't completely dark for half of the year)
Year: 458 earth days
Climate: Similar to Cretaceous earth
Atmospheric density: 1.1 earth
Surface Pressure: same as earth
# of Satellites: 2

Freyja is the fourth planet of a binary star solar system. It is in the Goldilocks Zone of it's parent star, meaning liquid water is possible on the planet's surface. Put in our solar system, Freyja would be about halfway between the Earth and Mars. Despite being further from it's sun than earth, the climate is comparable to late Cretaceous earth (warmer than present day earth) thanks to the higher levels of carbon dioxide and oxygen . The atmosphere is about 10% denser than the atmosphere on earth and is poisonous to humans. On Freyja storms are stronger than on Earth thanks to greenhouse gases and two suns.
Freyja has complex life on it's surface, ocean, and in it's skies. Flying creatures take advantage of of low gravity and high air density, allowing them to grow larger and still fly. Terrestrial creatures can grow larger as well. There are no sentient lifeforms on Freyja. In its atmosphere, there are thick living clouds of air plankton (green clouds). (You've probably noticed that i haven't said plant or animal. That is because many of the creatures i have in mind combine animal and plant characteristics.)
Freyja has two moons. Bygul is 2/3 the size of earth's moon (making the proportions for Freyja and Bygul the same as Earth and its moon). Trjegul (the one with the crater is 1/2 the size of earth's moon.

Freyja is named after the Norse goddess of the same name. It's two moons are named after Freyja's cats that pull her chariot.

I think Freyja should be a super-earth.

Terrestrial tetrapod with massive weight and pillar-like limbs (such as the behemoth) are more suited in a super-earth planet with high gravity rather than a sub-earth planet with lower gravity. The availability of open space is also plays important role in the spreading of these massive beasts, and of course a terrestrial super-earth planet is a better option.

Tall slender terrestrial beings with lighter weight are probably more suited for a sub-earth planet.

Anyhow, Heart  your work!

And a sub-earth wouldn't have enough gravity to keep those rings together.

I made it a sub earth for the lower gravity. But I'll consider it

If the gravity is lower than Earth's, then it shouldn't have rings.

Fantastic planet, and I love the fauna you've posted so far. Are there sapients on the planet?

Thanks! No, there are no sapient creatures on Freyja. However, the 3rd planet in the same system has a sapient species. jbpaleoart.deviantart.com/art/…

Also fantastic- I really need to focus more on my planets. I design random creatures but never assign them to any specific place. Though I do have several planets designed. What's your technique for maps?

I'll have to check out your creatures. I use photoshop cs5. I use difference clouds and the gradient map tool mostly. It's a pretty common technique. There are alot of tutorials on google. To make the planet I just make a circle on the map and spherize 100%.

Well I'll try that on my next series of planets. I see you've already seen my inner orbital ones, I'm doing the terraformed moons of Jupiter next. Do you have any other planets?

Only the two. I plan on doing a few more for this system

So, how big in theory could the native fauna grow with an atmosphere like that? i love the little ring around the planet btw! ive always loved plaets that have rings :)

Me too lol. As for how big, my behemoth is probably about as big as a land creature can get on Freyja. It depends on gravity, oxygen percentage, the amount of food that is available, body density, and some creatures could have air sacks which help decrease weight. I haven't drawn any ocean creatures yet, but gravity isn't much of a factor so the creatures will probably be larger.

I look forward to seeing the water creatures :3
i mean if the land creatures look this interesting,i must say..i can imagine what the sea creatures will look like :3

I'm actually having a hard time coming up with water creatures. Mainly because some of my land creatures have been inspired by earth's water creatures. Using up all of my weird ideas lol need to save a little for the water

if you need some inspiration for truly weird looking oceanic critters,try looking at some sipohophores, they are so weird.

Amazing...

With such a low gravity and oxygen-rich atmosphere, I bet the native fauna can grow really big, much like the dinosaurs on Earth... or even larger!
