Underwater

Underwater is a planet located in the large bodies of water of the planet Earth, the third planet from the sun, just next to its sister planet Japan. It is often believed to be the homeworld of the ancestors of all life on Earth. Though it shares a surface with the Earth, it is such a strange ecosystem that it is classified as its own planet.

Geography

Underwater is composed of five main binary orbit planets called Pacific, Atlantic, Indian, Arctic and Antarctic, and of moons of varying sizes known as "ponds", "lakes", and "seas". Connections between bodies of Underwater, known as "rivers", exist, and also seem to carry fish. They also carry minerals, which seems to be the reason why salt is abundant on the largest underwater environment.

Climate

Underwater's atmosphere is mostly water. It is not breathable by most Earthlings, though its lifeforms have adapted to breathing it. Its ground is mostly sandy, and possesses its own, tendril-like plants, known as algae. It receives light from the Sun of its sister planet Earth, though if you go deep, deeper, yet deeper, the sunlight will travel to you slow, slower, yet slower, it will get dark, darker, yet darker, yeet darker, yeeeeeeet darker, and you will encounter all sort of strange, stranger, yet stranger, yeet stranger, yeeeeeeet stranger fish, though you should wear a special spacesuit created for this strange planet if you don't want yourself to get crushed by the water above you, more of it, yet more of it, yeet more of it, and yeeeeeeet more of it.

Flora

Underwater has been shown to be home to various strange plants, which are the strangest at its the tentacled anemone, the sponge, which has been classified as an animal due to its sperm-like pollen, and of course the coral, which is actually a cluster of animals called the polyp(again, an animal).

Fauna

The most common species from Underwater is the silver-scaled, water-breathing, lidless creature called the fish, but there are also other strange types of animals, such as the insectoid lobster and shrimp, the sideways-moving, pincer-legged spider insectoid called the crab, the tentacled, poisonous, transparent, umbrella-headed jellyfish, the serpentine eel, and, in smaller bodies of water, the slimy, sideways-pupilled, larval-staged frog, and its cousin, the neotenous, frilled, regenerating axolotl, not to mention some birds that float on the threshold between Earth and Underwater, such as the long-necked traffic cone-beaked swan, the green-headed duck-billed quacking duck, and also the goose. Underwater is also the home of the large, plankton-eating fan-toothed Playboy scum on top whale.

sentient species

There are about two sentient species originating from Underwater, they're called octopi and dolphins.

Dolphins

Dolphins have been found to rape, to help other dolphins give birth, and to hunt for fun, but also to help people. Their chirp language seems also to be complex. Despite evidence of their sentience, humans have also enslaved dolphins into doing acrobaties for their amusement.

Octopi...I mean Octo...Puses, yeah, it's Octo...Podes??? SOMEBODY HELP ME PLEASE OR ILL KILL MYSELF!!!

Octopi, an iconic species, and the basis for many aliens, have demonstrated excellent problem solving skills, having passed nineleven billion tests. Their psychology is strange, with each tentacle having its own semi-independent brain, who actually obeys the main brain instead of just being mind-controlled by it, much like how you obey(ed) your parent(s)/teacher(s) when (s)he tells you to do something. Yeah they can't disobey, but they can figure out how to do what the main brain told you. Like when you accept to do a chore, but you can do it any way you want... It's strange.
