[OC] Slime Pools

[OC] Slime Pools

you might have noticed that I’ve only been posting marine organisms. it’s for a good reason! I’ll first be posting about 50 marine animals +30-40 flora, then 50 terrestrial animals +30-40 flora, then 50 animals +30-40 flora on the night side of the planet. I’m not gonna post each one one at a time. I’ll likely stop posting for a while then just give a whole slideshow of all marine animals, then do the same for flora. um idk if this counts as an animal, but I’m just gonna count it as one

slime pools:

It sits in its rock crater, perfectly still. When an animal swims by, the slime would rapidly surge upward, enveloping the prey entirely. Once the prey is trapped inside the slime's gelatinous body, the enzymes are secreted in a sealed environment, turning the prey into a nutrient-rich soup. The outer skin of the slime hardens to lock the prey in, while the inside turns into a caustic, enzymatic furnace, dissolving the animal into a liquid in a matter of hours. In fact, when the outer layer hardens, that is the upper layer organisms in the colony actually killing themselves. It works kinda similar to skin cells!

They live in craters/bowls on the sea floor, which makes it kind of like a pool of slime. It’s a colonial organism

it’s bioluminescent to attract prey

surface layer of the colony feature glowing, tentacle-like structures. To a passing fish or crustacean, this would look exactly like a bed of harmless, glowing sea anemones

When the outer skin hardens the bioluminescent lights will abruptly go out

The bottom layer of the colony consists of specialized, acid-secreting units. They constantly maintain and deepen the crater, ensuring the colony remains anchored against ocean currents

The middle layers are a dense, gelatinous matrix packed with inactive digestive enzymes (zymogens) safely stored away so the slime doesn't accidentally digest itself.

These organisms reproduce asexually.

[OC] Drill Serpents

This concept made sense in my head, but was very difficult to explain, so it took me a lot of research, which is why I took so long to post. anyways, this is likely going to be my most complex organism. I’m actually very proud of myself! didnt think I’d be able to make something like this! honestly my favorite organism out of all the ones I’ve ever made

Drill serpents:
Tricone drill shaped head. utilize massive torque to drive three independently rotating, interlocking cone-like mandibles into the substrate to pulverize rock. Instead of a single solid boring tooth, the head would feature three conical, cone-shaped mouthparts. As the serpent twists its head, the rock's resistance would cause these cones to counter-rotate. The cones would be studded with dense, ultra-hard serrations (like tungsten carbide teeth in real drills). The downward push ("weight on bit") causes the teeth to impact and shatter the rock, while the specific offset of the cones causes a gouging, scraping action that shears the rock layers apart. To generate enough "weight on bit" without fracturing its own skull, the serpent’s head capsule would require an incredibly thick, reinforced cuticle heavily mineralized with iron, zinc, or silica (similar to the hardened jaws of some leaf-cutter ants). It has specialized, hypertrophied muscle bundles anchoring to a massive cephalothorax (or large head capsule) to drive the main drill shaft. They excrete a specialized acidic or lubricative fluid to soften the rock, combined with strong muscular throat pumps to ingest or siphon the pulverized rock dust out of the borehole. the joints connecting the rotating cones to the main skull have thick, flexible articular membranes and specialized shock-absorbing ligaments to prevent self-destruction from vibration.The drill serpent would need to secrete a fast-hardening, concrete-like saliva or silk slurry. It would plaster this fluid onto the freshly drilled walls using its abdomen or rear legs to prevent cave-ins. It would require "gripper" appendages. These would be massive, hydraulic-powered lateral spikes on its thorax that lock hard into the side walls of the tunnel, providing a solid anchor so the front half of the body can push forward with maximum crushing force. The creature would need a massive respiratory system. It might actively pump air through specialized, reinforced spiracles along its sides, or spray a continuous mist of chilled, water-based metabolic waste onto the drill head to keep the tissue from cooking. In early stages of life, the creature has features that allows it to dig the fine dust and gravel out, which is why these creatures always bring groups of younger ones with them when digging, to prevent the debris from suffocating them. 

The "gripper" spikes on the thorax act exactly like the hydraulic pads of a real Tunnel Boring Machine. When extending the drill head, these spikes lock into the tunnel walls so the serpent doesn’t just push itself backward.

The thorax/head houses the hypertrophied muscle bundles and protects the vital organs from the immense pressure.

As the serpent moves forward, its elongated abdomen follows. The rear appendages (perhaps modified, paddle-like legs or spinnerets) smooth out the secreted concrete-saliva slurry, acting like a trowel to leave behind a perfectly smooth, reinforced tube.

The reinforced spiracles along its sides double as a ventilation system. As it pumps air, it forces toxic rock dust and heat backward, away from its face and toward the tunnel exit.

The younger serpents likely possess wide, shovel-like front appendages or scoop-shaped heads (which they lose as they mature into tricone adults).

They follow directly behind the parent, scoop up the heavy debris, and transport it to the surface. This creates a literal assembly line, making the Drill Serpent a devastatingly efficient ecosystem engineer.

these tunnels are basically a network of tunnels, kind of like with ants. when multiple tunnels meet, they make large caves. these caves are usually made for resting/sleep, or are places where they put their eggs, or where they mate

Their digestive tracts house highly specialized, symbiotic chemotrophic bacteria (similar to deep-sea hydrothermal vent life). These bacteria break down the crushed iron, sulfur, and copper ores siphoned up by the throat pumps, converting chemical bonds into metabolic energy. To maintain their ultra-hard, mineralized exoskeletons and carbide-like head teeth, adults absorb heavy metals directly from the rock dust. What they cannot digest is excreted as the concrete-like saliva slurry used to line the tunnel walls.

Juvenile Drill Serpents cannot yet digest raw rock, as their digestive systems and gut bacteria are still developing. Instead, they rely on a complex agricultural system within the colony. As the young clear the gravel out of the tunnels, they scrape this bio-film and fungus off the older tunnel walls. They also act as apex predators to the other animals who live in these tunnels. This fungus provides the protein and moisture needed for rapid growth, slowly inoculating their guts with the bacteria they will need to digest rock as adults.

Juveniles use their shovel-like front appendages to bury themselves in the debris piles. When an intruder falls into the tunnel, the young explode from the gravel, using sharp, scissor-like pincers (which later fuse into the tricone head) to snap up the prey.

Adults gently vibrate their tricone mandibles against the rock face without actively spinning them. They detect the returning vibrations through specialized slit sensilla (vibration-sensing organs) on their legs, creating a perfect 3D sonar map of the solid stone ahead.

The cones counter-rotate against one another

the head capsule itself twists back and forth in a 180-degree or 360-degree reciprocating arc (clockwise, then counter-clockwise). The resistance of the rock causes the individual interlocking cones to roll and spin continuously along the rock face, crushing it without twisting the internal tissue off.

Appearance:

Adults:
The tip of the head has no eyes, nose, or traditional face. Instead, it terminates in three massive, triangular, interlocking mandibles shaped like heavy Tricone Drill Bits. These cones are a metallic, dull gray-black color, heavily encrusted with rows of diamond-shaped, tungsten-carbide-like serrated teeth. When spinning, the mouth looks like a churning, metallic vortex.

Directly behind the drilling mandibles is a bulging, heavily armored head capsule. The exoskeleton here is thick, matte-black, and reinforced with a bumpy, iron-mineralized texture. It lacks external features except for a ring of deep, forward-facing sensory pits that detect vibrations.

The front third of the body is thick and muscular. On either side of this section are two pairs of massive, hydraulic-like anchoring spikes. These spikes are thick, curved, and heavily scarred from being driven repeatedly into solid granite.

The rest of the body stretches out like a massive, armored python, covered in tightly overlapping, dark iron-gray plates. 

The very end of the serpent flattens out into wide, smooth, paddle-like plates. These flat appendages are covered in a slick, secretion-resistant coating used to smear and smooth out the wet, concrete-like saliva slurry onto the tunnel walls.

Juveniles:
Unlike the adults, the young have a highly visible, wide, spade-shaped head capsule. This flat, hard shield acts as a living bulldozer scoop for pushing gravel.

While adults are completely blind, the juveniles possess small, milk-white, vestigial compound eyes on the sides of their heads

Their bodies are shorter, stubbier, and less heavily armored than the adults. Their front legs are modified into oversized, serrated, shovel-like pincers. They use these to aggressively scoop rock debris backward beneath their bodies or to snap shut on intrusive cave-dwellers.

Drill serpent eggs exist in a form of natural stasis, awaiting appropriate hatching conditions.

Also, since they’re cnithropada, they start off without an exoskeleton when they’re born, but they develop them later on as juveniles. Just wanted to clarify this. If you don’t remember what cnithropods are, here’s their description: Cnidaria + Arthropoda analog.
Chitin exoskeleton and soft gelatinous interior like a jellyfish. They are 75-95% water, have a decentralized brain, a gastrodermis, and a protective exoskeleton made of chitin. Most reproduce sexually and lay eggs. As larvae, they do not have their exoskeleton of chitin yet and develop it as they get older. They have to molt to grow. They have an advanced system of muscles attached to the inside of their exoskeletons. Specifically, drill serpents are on the lower end of water concentration. Their bodies are 78% water.

Habitat/life span:

they live in the twilight zone, and live until about 170 years old.

Edits:
Instead of needing to internally store and spray precious water reserves, the throat pumps can continuously draw in ambient water, slurry it with the rock dust, and blast it out of the steam/vent spiracles.

The adult's drilling action, combined with its powerful throat pumps, creates a localized low-pressure zone at the rock face. It essentially acts as a dredging pump, fluidizing the pulverized rock dust into a slurry that can easily be funneled backward over its body to the waiting juveniles.

An underwater boring lifestyle means the tunnels are constantly flooded with mineral-rich, oxygenated seawater or sulfur-heavy geothermal water. This provides a literal buffet for the symbiotic bacteria in the serpent’s gut. The juveniles grazing on the biofilm of the older tunnel walls perfectly mirrors how deep-sea snails and shrimp graze on vent chimneys.

the serpent would need to secrete an underwater-curing biopolymer, heavily inspired by the protein glues used by barnacles and mussels, or the heavy mucus tubes of phoronid worms. This fast-curing bio-cement would react chemically with the ions in seawater (like magnesium and calcium), sealing the tunnel walls to prevent the high pressure of the ocean floor from collapsing the tunnel inward.

The serrations on the tricone mandibles incorporate heavy metals absorbed from the rock dust—specifically iron sulfides (like greigite) or zinc.

The joints of the mandibles are lined with thick, elastomeric articular membranes and specialized protein-based ligaments. These act as biological shock absorbers

As the main head twists, the three interlocking, conical mandibles press against the rock face. The friction and resistance of the substrate force these independent cones to spin on their own internal axes. Because the cones interlock and are offset, they naturally counter-rotate against each other. This dual-action motion creates a devastating combination of compression (shattering the rock directly ahead) and shear stress (scraping and tearing the rock layers apart at an angle).

An unanchored drilling apparatus will simply spin the drilling vehicle in circles. The Drill Serpent solves this via a dual-stage anchoring cycle modeled directly after a modern TBM

[OC] moonfish + quilt squids (and their language)

sorry if these illustrations are kinda bad😭 I don’t consider myself an artist like at all. At least the low quality allows me to draw these in only like an hour so I can post frequently. Also if u have any other questions about how any of these animals live, just ask me! It helps me to develop them further

moonfish are apex predators about the size of great white sharks. they live in kelp forests and hunt by using their bioluminescent skin flap thingy. they live in packs of 3-8 and have their own form of communication using their skin flaps’s light. Despite being apex predators, they have been seen to express “nice” behavior to animals they don’t see as prey, even going as far as to adopt lost animals. They have high emotional int and empathy, which likely evolved for them to stay in their packs.

quilt squids are a highly intelligent species. They are based off of blanket octopuses (yes octopuses is a correct plural form of octopu, you can search it up). They can basically be found all around the ocean (because they travel and stuff) but the habitat they originally come from is a system of hydrothermal vents in the sunlight zone of the ocean. this allowed them to develop metallurgy and cooking. quilt fish have a bioluminescent ink at the tips of their ribbon-like tentacles (not the two next to the head), which can be used kind of like pens! that is how they developed a written system of language. there used to be multiple languages, but their society merged as they advanced, which turned into one language. the language is called kouverta (which means blanket). it is a logographic language, meaning that the symbols represent entire words instead of sounds. symbols can be combined to make new words. currently, quilt squids are not as advanced as they used to be, which is because of the apocalypse caused by the war between them and the progenitors. I’ll explain who the progenitors are in another post!

also, I’ve kinda changed up the project. Scylla isn’t a moon of a gas giant anymore, but a habitable eyeball planet. I’ll still be keeping a lot of stuff from the previous versiom though, so no need to worry!

[OC] Sea Bees + Hydrocyatha

had to repost cuz I forgot to add the brown flipper thingies the back side for the sea bees😭

sea bees are a family of organisms that are aquatic and live in reefs. the image above is a species of sea bees. They live in hives of 100-1000 sea bees. They use hydrocyathans as their hives. They tend to be about the size of a bumblebee, but the queens are usually about 2-2.5x bigger. They are part of the cnithropoda phylum (which are basically a mix of cnidarians and arthropods. All u need to know is that they have jellyfish-like bodies on the inside and chitin exoskeletons on the outside). They have a large singular eye at the front of their “face” with the blue around it actually being their soft interior body exposed. Their diets mostly consist of algae and plants. They live for around 1-2 years. They have surprisingly high intelligence and can be seen communicating with each other, and are very loyal to their hives but aggressive towards other animals. But if you find one from birth and raise it, it’ll be very loyal to you. Likewise if you help one in danger or in a tough situation. Here’s a picture of a hydrocyatha. They’re based on archaeocyatha. Basically they’re just sponges. I’ll probably do a more in depth post on them later!

most of this info applies to all sea bees, except for the size, behavior, and life span

also, I basically resettled my spec evo project. Scylla is not the moon of a gas giant anymore. It is an eyeball planet orbiting a red dwarf star. Here’s the fauna + flora you should be expecting to see. I’ll add more in depth descriptions and more stuff as the project goes on. Flora phyla:

Chlomyphyta: Chlorophyta + Chytridiomycota

They produce both gametes and diploid zoospores that swim with the help of a single flagellum.

Mostly freshwater habitat

Both sexual and asexual reproduction

Store energy as starch within their plastids

Composite of cellulose and Chitin cell walls

Filscomyphyta: Ascomycota + Filicinophyta

Cell wall is a composite of chitin and cellulose

Stores energy as Starch (Fern trait) in the fronds and Glycogen (Fungal trait) in the rhizomes.

Instead of a simple root system, it would have a thick underground rhizome that sprouts fine fungal hyphae to actively digest organic matter in the soil while the "fronds" gather sunlight.

On the underside of the fronds, instead of simple sori (fern spore clusters), you would find Apothecia (cup-shaped fruiting bodies).

produce Ascospores (usually eight per sac) that are shot out via hydrostatic pressure

After spores germinate, the resulting mycelium would need to undergo plasmogamy (fusing cells without fusing nuclei) to develop the strength required to grow the large, vascular "fern" structure.

Balycomyphyta: *Basidiomycota** + Lycopodiophyta

Unlike true leaves, these "microphylls" would be covered in a fine hymenium (fertile layer). Instead of green mossy spikes, the leaves might have a leathery or velvety texture, housing Basidia (club-shaped cells) that produce spores.

Following the Lycopod body plan, the main "stem" would split into two equal branches repeatedly, but the "stem" itself would be composed of pseudoparenchyma (tightly packed fungal hyphae) reinforced with lignin.

Strobilus (the cone-like structure at the tip of clubmosses). the cone is actually a complex fruiting body. Instead of scales opening to drop seeds or plant spores, the "cone" would function like a Puffball. The spores (Basidiospores) would be "shot" off the cone using Buller’s Drop (a moisture-tension mechanism), allowing the "moss" to actively propel its offspring into the wind.

Cell wall made of a composite of chitin and cellulose

globryomyphyta: Bryophyta + Glomeromycota

Large asexual spores

Asexual reproduction only

Aseptate hyphae

lack specialized vascular tissues (xylem and phloem) for water and nutrient transport

thread-like structures called rhizoids, which anchor the plant to surfaces

Cell wall made of a composite of chitin and cellulose

Bangiomyphyta: Basidiomycota + Angiosperms

colorful, petaloid Hymenophores

In angiosperms, two sperm cells are used (one for the embryo, one for the food source). In this hybrid, the "pollen" (specialized dikaryotic spores) would initiate a dikaryotic phase within the ovary, creating a "seed" that is actually a dormant, nutrient-packed fungal sclerotium.

produce both floral essential oils and complex fungal alkaloids (like lignin-degrading enzymes or toxins).

uses scent and color to attract pollinators

They also produce fruit

Cell wall made of a composite of chitin and cellulose

Zryomyphyta: Bryophota + zygomycota

Mostly terrestrial, found in soil, decaying organic matter, and as pathogens of plants and insects.

grow very quickly. They possess primitive, non-septated (coenocytic) hyphae, which are broad and multinucleated, allowing for rapid growth and cytoplasmic streaming.

have rhizoids, which are unicellular or multicellular filaments that anchor it to surfaces

predominantly reproduce asexually by producing sporangiospores inside sporangia, which are supported by specialized hyphae called sporangiophores.

Cell wall made of a composite of chitin and cellulose

Phaemyphyta: Phaeophyceae analog

sclerotia are fertilized by compatible mating types (conidia), allowing them to produce recombinant spores.

Primary carbohydrate reserves are complex polysaccharides, specifically laminarin and mannitol

Almost exclusively marine, found mainly in cold, rocky intertidal and sublittoral zones. They are multicellular, with forms ranging from branched filaments to massive seaweed-like ones

Cell wall made of a composite of chitin and cellulose

By the way, most flora are colonial. Colonies can be nested inside of other colonies. 

Fauna Phyla:

Hydrocyatha: Archaeocyatha Analog

Cnithropoda: Cnidaria + Arthropoda analog
Chitin exoskeleton and soft gelatinous interior like a jellyfish. They are 85-95% water, have a decentralized brain, a gastrodermis, and a protective exoskeleton made of chitin. Most reproduce sexually and lay eggs. As larvae, they do not have their exoskeleton of chitin yet and develop it as they get older. They have to molt to grow. They have an advanced system of muscles attached to the inside of their exoskeletons

Mullinodermata: Mollusca + echinodermata analog
Bilateral symmetry
an endoskeleton made of calcareous ossicles
Water vascular system
Nerve ring
Muscular foot
Soft, unsegmented bodies

Cnithropoda: Mollusca + Cnidaria analog
Radial symmetry
No skeleton
Centralized nervous system
Soft, unsegmented bodies. often protected by a nacre shell secreted by a specialized tissue called the mantle
Stinging cells
2 muscular feet

Echithropada: Echinodermata + Arthropoda analog
Chitinous exoskeleton
Segmented bodies
Larvae start out with bilateral symmetry but undergo metamorphosis into pentaradial symmetry
Reproduce either asexually or sexually
Open circulatory system
Have to molt
Jointed appendages
Centralized nervous system
An internal aristotles lantern
Gills

live attached to surfaces or be slow-drifting, relying on sedentary or planktonic lifestyles. sessile or slow-moving, filter-feeding organisms lacking specialized heads

Chordonia: Chordata analog
notochord, dorsal hollow nerve cord, pharyngeal slits

Verticata: Vertebrate analog
Endoskeletons made of nacre
Six limbs
Backbone
Bilateral symmetry
Closed circulatory system
Decentralized but advanced nervous system that works as well as a brain. Basically their brains are tubes that are all around the body (like veins and stuff) and do everything the brain does, and send signals to the nervous system.

so this is a cool new magic system idea I came up with like 2 hours ago. I made it literally today so please feel free to give feedback and suggestions! Also I don’t have the names for the god-like beings or the two other types of beings made up of mnemonic energy, so any ideas would be appreciated!!

Magic system: people derive their power from their memories, specifically they are used as fuel for magic, which is called mnemonic energy. Your memories shape the abilities you have. Since everyone’s memories are different, everyone’s ability is unique to themselves. The more memories you accumulate, the stronger you become. To use greater acts of strength or magic requires more memories to be used up, while smaller amounts use less memories. All used up memories go into a place called Anamnesis, where all the memories in the world are stored. This is also the case for when organisms die.

There are also these god-like beings who are memories of specific aspects of the world, such as memory of chaos, memory of life, memory of death, memory of time, memory of wisdom, memory of water, memory of fire, etc. 

There is an energy called oblivion. It has the ability to erase memories, and is very harmful, especially when it affects the world’s memory (Anamnesis). When something is forgotten by the world itself, that thing will slowly fade away and cease to exist. Oblivious energy can condense into monsters called amnesiacs.

You can sacrifice all of your current memories to create a memorial seed. This will grow into a memorial tree, which spread mnemonic energy through their roots, and are the only things capable of helping the world to remember things that were forgotten by oblivion. But if the thing has already ceased to exist, the world will not be able to remember it no matter what. Memorial trees grow memorial fruits, which are full of mnemonic energy. When eaten, they provide you with mnemonic energy that can act as a replacement fuel instead of your memories being used up. They also can help people with amnesia to regain their memories. But it will not regain the memories of people who used their memories as fuel to make mnemonic energy, because the memories aren’t actually gone but are somewhere else. Likewise, it cannot be used to regain the memories of people who used their memories to make memorial seeds.

There are three types of being that are made entirely out of mnemonic energy. The first type are beings who are from specific memories. For example, someone’s memory of their best friend could turn into one. The second type is being made out of condensed mnemonic energy, which can happen naturally or artificially. The third type is the god-like beings mentioned earlier.
