Did you know that 4000 metres bellow the ocean there are chemosynthetic bacteria that are specifically evolved to digest the wood of trees that have grown on land?
The wood on the sea floor can come from trees that fall into lakes and end up in the ocean, or wooden ships that have sunken. (Called 'Wood-falls')
The reason why deep marine organisms are able to digest wood despite never seeing the light of day, let alone a plant - since plants are unable to grow in the deep ocean because of a lack of sunlight - is because the ocean is so isolated and scarce of food that when a new food source is suddenly available, organisms rapidly evolve to be able to eat it.
This is called 'Adaptive Radiation', and can also occur on isolated islands.

Imagine this.
Danny, Jimmy and Timmy realised their portal machine somehow was broken and they had no way to teleport to Spongebob鈥檚 dimension.
In a desperate attempt, Timmy uses his fairies' last magic to teleport them somewhere near Spongebob鈥檚 house.
That fails.
They get teleported to the island
Tumblr media
They decide its the best they鈥檝e got so they gear up and dive in.
Jimmy came prepared with inventions to help them breathe so it was good until they have to go through each layer of the ocean.
Tumblr media
Then they start to see the most other-worldly creatures of the marine life. And they wondered how their friend even survived down here.
I like to think they were tiny like the size of Spongebob. I like to think humans in Spongebob鈥檚 dimension are like, titans.
I want them to explore the horrors that lie on the ocean floor.

Astroscopus guttatus, or the Northern Stargazer is a sedentary ambush predator of the western Atlantic, at depths of, roughly, 36 meters (120 feet). They spend the majority of their adult life buried in the sand of the ocean floor.
The name of their genus (as well as their english name) is derived from the fact that its eyes are positioned on the top of its head, allowing it to see above it. It can also extend its eyes temporarily by filling sacs behind them with liquid. Its body is adapted to its sedentary lifestyle, with frills covering its mouth to prevent sand from falling in, the uncommon ability to breathe through a pair of nostrils and shovel like pectoral fins. What really makes this fish distinct is its ability to discharge electric shocks from an electric organ on its forehead as a defense mechanism (the indent above its eyes).
They live almost completely solitary lives, only interacting during mating season, or the occasional larvae cannibalizing another larvae (it's technically an interaction lol). They will attempt to eat pretty much anything small and thats foolish enough to get close to it. They have few predators (barring humans) due to their electrical defense.
sorry for the lack of pictures, these fish are pretty ugly + theres not a lot of pictures of the correct species.

in the deep ocean there are things called brine pools, which are essentially lakes of water separate from the ocean water. they're formed when water seeping through the ocean floor mixes with salt deposits, so the actual brine pools themselves are too salty and too toxic for most things to live in. but because they're so mineral rich, there's a bunch of really cool things living around them!
some examples include mussels, crabs, echinoderms, and sea cucumbers.

C.W: Whale corpses
Tumblr media
When a whale carcass floats down to the ocean floor in the abyssal zone, it creates an ecosystem called a 'whalefall', where a variety of deep marine life can live and be sustained for over 50 years.
This ecosystem has 4 stages:
Mobile Scavengers Stage
Tumblr media
The first stage is when scavengers from around the plain gather to feast on the whales flesh - Typically by hagfish and sleeper sharks - until there is just bone.
This stage can last for months or up to 1.5 years.
Enrichment Opportunists Stage
Tumblr media
This stage is when smaller scavengers - such as octopuses, crustaceans and molluscs - gather around the whale looking for tissue and bits of carcass left over from the first stage. This is also when osedax (boneworms) arrive and comsume the community of bacteria that eat the bone lipids.
This stage can last months or up to 5 years.
Sulfophilic Stage
Tumblr media
In this stage the majority of scavengers have left and in its place are the boneworms and the community of chemosynthetic bacteria that break down the lipids in the bones and produces sulphide that can be consumed by other organisms like worms or shrimp.
This stage can last over 50 years.
Reef Stage
Tumblr media
The final stage is when all the consumable material have been exhausted and the leftover bone creates a hard surface for abyssal filter feeders to latch onto. A 'reef' of sorts.
Whalefalls are one of many essential food-falls that sustain life at the bottom of the ocean, and are p cool i think anyway im done w my autism rant goodbye
