Well, sorry but I felt it had to completely redo the entire bottom portion of the landscape from the horizon line down. I looked at an interesting documentary on the different planets in the solar system and reaffirmed some facts, learned some new things, and realized I was mistaken on a few things.
I think this version is more visually dramatic. The viewer is below ground level looking into an eternity of crevices.
Also, I've incorporated a view of four species of very interesting and very exotic organisms.
Most noticeable are the most simple organisms on the planet. It's called Golden Algae. They produce a combination of stable metals that are highly lustrous such as gold, platinum, and silver. These metals are formed by breaking down or building up protons and electrons of heavier or lighter common elements such as iron, copper, oxygen, and silicon. They collect loose protons and neutrons that rain down from Jupiter (which is at fatal levels for humans) and utilize this high velocity particle energy to generate new elements. Their cells have microscopic biological versions of atom smashers capable of producing intense pressures and super cold temperatures at seemingly impossible efficiency to shield their genetic material from destructive radiation. The gold, platinum, and silver make up their cell walls in combination with a complex similar to collagen or cellulose. These precious metals actually refract and scatter the deadly radiation. This species of gold algae lives in colonies near the edge of the liquid water where the black algae needs to live.
Gold Algae needs black Algae to survive because Black Algae produces sugars from the white light which is produced by the Gold Algae's bioluminescent components. The sugars are transferred to the Gold Algae through a network of veins to be burned aerobically from O2 which is also produced by black algae but transferred through the veins. These two organism depend exclusively on one another except for the Harp slugs.
Harp slugs are fast swimming animals that eat black algae but not gold algae. The black algae usually grows directly underneath gold algae so to get to it, the slugs actually melt through the ice underneath both algae to feed just on the black algae. The algae is black because it has a type of photosynthetic cellular component called melaplasts similar to chloroplasts in plant life on earth. Melaplasts are highly efficient nuclear powered factories that convert white light and CO2 into carbohydrates. The slugs use the melaplasts for its electrical energy and nuclear efficiency, not for the food. These slugs actually absorb radioactive hydrogen atoms in the ice and convert them into the two most stable elements of carbon and nitrogen. It's a slow process and early in their evolution they resorted to cannibalism for fat. As a result, there are now many many varieties of these slugs, some with subtle differences, others that are barely recognizable. These slugs are veracious and very hostile. One sub branch of these slug species are very territorial, very adaptive, have advanced vision, eight tentacles, large brains that learn fast, and can even use some pretty complex tools like titanium tipped bronze. They are primarily in competition with a hiving species of slugs that domesticate some other species of slugs and algae who on an individual basis are not intelligent but together are a highly successful super organism. Something like leaf cutter ants. The intelligent slugs are purple and have bioluminescent cells on their skin that change patterns for visual communications and also to see in the dark depths of the single ocean on Europa. Other Lemon shaped slugs that use jet propulsion are illuminated by the light emitted by the intelligent slugs.
The lemon shaped slugs are almost transparent and use a simple single-valve mechanism to suck water in through the mouth and expel it through a nozzle that can change vector to gracefully pulse through the water, kinda like a jellyfish but instead of like an umbrella opening and closing, it's more like a balloon with openings at opposite ends inflating in one mouth and deflating through the other.
Of course, it's all totally speculative, some of my concepts of cellular atomic fission and fusion are probably not even possible, then again it's speculated that sodium in humans is fused at body temperature to create lithium. I forget exactly why.
