We have three creatures to start with. All have the sensory capabilites of a planarian, or some other simple creature.

> Flipper
Flipper is a mobile creature with a paddle-like tail that it uses to swim through the water. It eats plankton.

> Pinkie
A bottom dweller with 14 stubby legs. It feeds on detritus, sometimes substrate.

> Wiggles
Sedentary, attaches to rocks and catches detritus and plankton that pass by its feeding arm.

just edit the picture to show what adaptation you wish to give the critter.
Explain the reasons why the adaptation occurred.

Alternately, you can "split-off" a species from the main branch, rather than making it a furtherance of the previous critter.

Pinkie's mouth moves to the underside. As they crawl along the ocean floor, they sift through the dirt for food with the nubs along the rear of the mouth.

Some Symbiotic Flippers dont subscribe to more aggressive approach >>973624.
They split and stay purely symbiotic, moving up to service Superwiggle, Megawiggle, Ultrawiggle and Gigawiggle clusters.
In order to do so, their secreted fluid makes them appear to wiggle clusters as another part of a wiggle cluster.
Symbiotic Flippers also now shelter themselves inside wiggle clusters.

>>973718
the fluid secreted by the symbiotic flippers becomes the perfect medium for a new strain of super-efficient algae, as well as thickening to a jelly-like consistency. This lets the cluster wiggles harvest and grow much quicker, and the now mutualistic flippers benefit from the increase in food and shelter.

these new jetting flippers need a way of scouting out the area in front of them before shooting forward. they evolve a pair of muscular, fluid-filled membranes on their snouts. they use one to send out a sound pulse, than detect its echo with the second, going them basic echolocation. although it is efficient and reliable, they are unable to accurately hear while they are jetting forward; this works out for them, as they need to take breaks to drink up water between jumps, during which time they build a detailed map of their environment. they are now called blippers because I like puns and am a terrible human being

an offshoot of the slapper emerges. The slippery mucus has evolved into a jello-like cocoon that is used to enter wiggle megaclusters without being poisoned. However, some mupper ink is still able to diffuse through, so the new subspecies can't stay indefinitely. when it grows too difficult to breath, they swim back into fresh water and, using a repurposed slapping motion, throw off their old gel membrane.

some self-indulgent biology because I can't sleep:
megawiggle clusters begin at around two feet in diameter, but can grow to a maximum of 20 feet in extreme cases. they are able to support one mupper per cubic foot; any more, and the mupper population will 'prune' too many cilia for the megawiggle to replace, leading to the cluster starving and furthering the cycle.
Megawiggle grow by asexually budding new wiggles off of the ends of their three main tendrils. this continues until the sunlight that filters down to the oldest central wiggles is too faint for the algae surrounding them to survive, causing them to release hormones that halt reproduction. unfortunately, the muppers will continue to multiply, eventually disrupting the clusters equilibrium.
when the megawiggle starts losing too many cilia, the individual wiggles will do one of two things based on age: the majority of wiggles will begin regenerating cilia much faster, as well as pumping lots of sperm-like reproductive cells into the gel matrix. The original core wiggles, however, will retract their cilia and sprout three small 'fruit' at the ends of their tentacles. this fruit, actually a hardened egg casing, is very attractive to the overpopulated muppers. when eaten, the egg case will attach to the inside of the mupper, than take in the sperm and start to grow a cluster of new wiggles.
the host mupper, meanwhile, become both ravenous and highly antisocial. eventually, they will gorge themselves on cilia and flee the cluster. this is when the megawiggle embryos make their move: they kill the host once it has swam far enough from the parent cluster, and use the rich stores of nutrients to grow into a new, fresh cluster, restarting the cycle.
other stuff:
-while wiggle are simple enough to be technically immortal, they very rarely live past a century due to disease or overpopulation.
-wiggle clusters are semi-mobile: they slowly drift and bounce along the ocean floor, like a tumbleweed, to ensure sunlight reaches all sides evenly
-mupper are introduced to new nests by the infrequent spawning migrations they undertake, wherein large flocks will leave their home cluster to meet and lay eggs, before returning to a random new cluster. This has an interesting effect in the population of the two organisms: because of how dependent the wiggle is on the mupper for food and protection, any clusters spawned outside of mating season will likely soon die. however, if the waves of newborn mupper do not find a new home, the existing clusters will become overburdened and trigger reproduction. These factors cause the number and size of clusters to fluctuate wildly.
-the exact makeup of the bacterial micro biome contained within a mega wiggles jelly is unique between individuals; although it is mostly made of different specialized algae and plankton, a vast variety of other microscopic life thrives in these conditions. muppers use this to avoid returning home after mating

>>975369
I'm just going to keep writing until I pads out or run out of ideas. neither seems very likely :/
-As the cluster tumbles around, it will pick up tons of detritus, as well as the occasional live organism which is quickly suffocated or poisoned by the gel. Since muppers are solely able to eat wiggle cilia, and cilia only eat photosynthetic plankton, it would seem that these sources of nutrients and energy would go to waste. However, the 'gut' bacteria serve as decomposes, quickly breaking down dead organic material to be absorbed by the superorganism and its symbiotes.
-While clusters typically do very little to control their motion, they need to stick to fairly shallow water to get enough light. The biggest danger a cluster faces in everyday life is being carried by an unfavorable current into deep water, where it will slowly starve. Mega wiggles do their best to work together and stay near the surface, but have trouble communicating quickly enough.
-One use that the wiggles do get out of mobility is a crude circulatory system for the cluster: by working together, they are able to gently cycle plankton between the sun-rich outer layers and the darker interior, where they are used to feed the core wiggles. They also use this system to concentrate decomposer bacteria around decaying organic matter, and helping build up toxic mupper ink around the edges of the cluster to deter predators
-muppers are hermaphroditic, and after mating, will carry a large clutch of eggs back to a new wiggle cluster, where they help each other form nests out of congealed slime. These eggs will hatch after a few months, but only take 2-3 weeks to reach reproductive maturity. This is to help space out the cycle of bloom and death in the mupper population.
-As second level consumers, mupper get little energy, and most of what they do get from wiggle cilia is used to make toxins, replenish gel, or mate. They spend most of their time drifting around the cluster in flocks, conserving energy and following the current of the algae circulation.

>>974176
-Blipper are some of the largest single organisms on fortune, almost a foot long. They use their speed and size to avoid predation by pinkies or slappers, and thus have few natural predators. Unlike most other flipper descendants, they do not having a communal mating season, instead exchanging genetic material whenever two cross paths. During this rather lengthy process, the two are at their most vulnerable, and to avoid opportunistic predators, they will often dive as deep as possible for the duration. This is much farther down then the rest of fortunes marine life, both due to their size and the unique pressure modicicatiobs needed to support the water jets.

>>974164
Sluggles are some of the few organisms who can survive in clusters, due to their thick skin and simple exterior anatomy. To take advantage of this, it isn't uncommon to see sluggles try to purposefully and slowly move into the path of an approaching megawiggle. Once inside, they are able to use quick swipes of their tentacles to scoop up bacteria, then retreat inside to digest it, as well as letting the toxin break down. They reproduce, like other wiggle groups, by budding off from their feeding tendril. While this is occuring, they will be much more careful around slappers, to the point that the tentacle is almost always retracted. Although filter feeding decreases as a result, they are able to store fat in the 'humps' of their shell for times of hunger. If too much fat is built up at once, the shell will bulge and expose the fragile skin underneath.

>>974154
slurpers do follow the trend, and will congregate at certain locations biannually to mate. They lay lots of eggs, which are put into a special slime membrane and buried under a thin layer of sand for two weeks, after which they start to hatch. most do not survive long, as they are dependent on wiggle clusters to eat, and must use a great deal of resources to build a cocoon. Sibling cannibalism is widespread. Because the gel membrane is filled with not only toxins, but gut flora and fauna, freshly discarded ones are sometimes mistaken for full wiggle clusters by 'pregnant' muppers after mating.

>>973971
Slappers have smaller, more irregular mating cycles, usually triggered when enough well-fed individuals happen to migrate close together. They stop eating to carry their eggs to term within their beaks, but after they hatch, the hungry mother will usually try to snack on a few of her children. Although no longer useful against wiggles, the eponymous slap they employ is still used against pinkiemedusa and hungry niggles, as well as to stir up the substrate to look for buried food. They use their tongues like a snake, flicking them out to catch scents and bringing them in to analyze them. Because if this, they can track prey for relatively long distances (several dozen yards, they are pretty small tho). Although it looks like they have nostrils on their beaks, I meant to draw a dolphin-like blowhole.

>>973919
Pinkiemedusa no longer eat cluster gel, and have gone back to feeding off of dirt. They use their leg frills to form a seal again the ground, and extends their mouths to eat everything within reach. They expel large amounts of inedible material out of their anus, which is also used to keep a lookout for predators. If one is spotted, they may try to escape, or try to discourage it by blasting it with ass-dirt in the face. They reproduce by mixing a wide variety of reproductive cells into their dirt geysers; if the right combination of cells combine it will likely grow to an adult. This is not very likely, both because the genetic material is at the whim of ocean currents, but mainly because pinkiemedusa have dozens of sexes, which must mate in certain combinations to be viable. Some genders include: egg, sperm, energy storage, material storage, shell builder, flagellum, digger, filter-feeder, stem cell producer, immune, nematocyst, chemosymthetic, venomous, poisonous, anchoring, and double egg. Not all sexes are necessary, obviously, and the specific grouping allows for a staggering variety of adolescent forms. This variety comes from the fact that all pinkie are technically examples of extreme symbiosis: they are actually separate colonies of specialized cultures that work together closely enough to function as a single organism. One or more of these species is ' dominant' in each pinkie, which determines which cells get to send out reproductive material. Although this does lead to competitive selection towards more dominant strains, if any one kind of cell becomes too prolific it will have trouble finding successful mating combinations. This ensures rough equilibrium in the different kinds of cells.

>>973666
The niggle is a fairly active and aggressive alpha predator, able to trap and kill almost anything within its three tentacles. Its biggest weakness is a lack of specialized sense organs, which forces it to rely on subtle changes in water pressure and flow. Niggles are much too active to form buds on their tentacles for too long; instead, they quickly grow and drop unfertilized eggs in the span of a few days. These are eaten by muppers, and trick them in to performing the same actions as if they were host to megawiggle offspring. Once they leave the cluster, however, they are directed to begin drinking as much water as possible in the hopes that they inhale a bit of niggle sperm. If so, the egg(s) will grow and consume their host, taking about 3-4 weeks. Niggle are fairly territorial, as the ecosystem of fortune can't support many tertiary consumers, and will brutally rip trespassers apart, even if they are fatally wounded doing so. Their teeth are the hardest parts of their body, and are connected to a complicated system of small bones and muscles that let them grind and manipulate food fairly delicately; due to the way their jaws function, they cannot close their mouths. Niggle are still similar enough to megawiggles to shrug off mupper ink, and will sometimes enter clusters in order to gorge themselves on both their distant cousins and the symbiotes the rely on.

>>973868
The non medusa pinkies use their flaps to tightly maneuver when jumping and, borrowing a trick from the slappers, can use their mouth-feet to deliver crushing blows to any predators. Like their close relatives, they are composed of symbiotic single-celled organisms; however, they have no dominant species, and instead 'take turns' producing and distributing reproductive cells. This cycles are often timed to allow certain favorable cell combinations to meet up at the same time for each turn, although different subspecies have different niches that they try to fill. The most common are a filter-feeding hard-shelled egg, a swimming & stinging parasite, and a secondary sessile stage that quickly divides itself to fill an area before releasing a burst of germinating embryos.
Because it lacks a frill to help contain the sand it kicks up while feeding, the baseline pinkie it much more mobile, steadily working through large tracks of sea floor and leaving distinctive furrows in the ground. It generally keeps its mouth unprolapsed, unless startled or threatened, in which case in will rapidly jump away or try to kick its attacker.
