Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

another thing, the corals are several polyps together, an anemone is like a great polyps alone and totally "evolved" right?

Well, corals are already sort of analogous to plants. They are sessile, spread asexually, and use sexual reproduction to establish new colonies elsewhere. Some reef corals might be able to grow without zooplankton to eat, and their zooxanthellae definitely help coral to grow.

I didn't read the whole thing, but here's a paper that explores the topic of whether we should consider corals autotrophs or heterotrophs: Reef Corals: Autotrophs or Heterotrophs?

Corals are a bit more picky than plants, which can limit where they grow. They like water to be consistently pretty warm, and tend to like stable salinities (they don't like growing near estuaries). They tend to have a hard time in intertidal areas because they don't like being exposed to air, but also don't like growing too deep because this limits the light they get (low light makes it hard for them to photosynthesize and secrete calcium carbonate). They also need clear water with little sediment suspended in it, as sediment can cover the coral and hamper photosynthesis and feeding.

So, even if they were entirely autotrophic, corals would have a hard time establishing a wider distribution.

And yeah, anemones are solitary polyps! Corals can also grow as single polyps, but they are distinguished by (among other things) their ability to secrete a calcium carbonate skeleton.
Both corals and anemones are polyp shaped cnidarians, which is essentially an upside down medusa (what jellyfish spend most of their life as).

um, I understand, but what about terrestrial cnidarians (not jellyfishes for obvious reasons)? for example, some primitive coral that came close to the earth or sticking to a rock, and that when the tide goes down it stays out (I do not know how could this happen because I think corals are sensitive to waves and things like that). but rather as solitary polyps (anemones) "walk" to a primitive land and develop it, and perhaps form some kind of terrestrial "coral plant".
these plant-like things are very interesting

So how plausible would this be?

A pitcher plant evolving bioluminescet to attract prey

Future project ideas:
Tale of the horned beasts - A alternate evolution project where ceratosaurus never went extinct and instead evovled to better fit the new challenges they shall face ahead of them.

Umber - A alternate universe project where portals have been opening up to a moon named "umber" other then a few species of freshwater and saltwater fish, as well as invertebrates. Pangolins,Iguanas,Noasauriade, and Cuttlefish are the most prominet group of animals.

Could a second lineage of volant arthropods conceivably evolve in the future? It's rather strange how it only happened once
Projects
Punga: A terraformed world with no vertebrates
Last one crawling: The last arthropod

ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)

Potential ideas-
Swamp world: A world covered in lakes, with the largest being caspian sized.
Nematozoic: After a mass extinction of ultimate proportions, a single species of nematode is the only surviving animal.
Tri-devonian: A devonian like ecosystem with holocene species on three different continents.

How small can a terrestrial vertebrate (a mammal) be? I was thinking of developing some kind of "rhinograde" (an analogue to them) but occupying a ninch like those of insects
and about flying? will it give some snouter flying by beating the ears or some kind of nasal tentacle that evolves into wings?
Are these things really plausible? Is this story of super-developed face muscles turning into limbs valid?

in the case I think more about the idea of the creature, based on a principle,for the project. I'm not creating anything just to create

Well some flowers use colours in the UV part of the spectrum to attract insects so you don't need to use luminescence, but I suppose it could happen. You'd just have to give a good explanation of how they developed bioluminescence and what they use (do they have bacteria that produces the glow, special light emitting cells etc)

What might live on Iceland after a future ice age? At the greatest extent of the last ice age about 10,000 years ago, Iceland was completely covered by ice. Today it is an island with only one native terrestrial mammal, the arctic fox. If it became became covered in ice again, then uncovered, it would essentially be wiped clean. What might colonize it?

Assuming polar bears can survive that long into the future I would say them. Some of them can become more suited to a terrestrial life like their ancestors and become rooted to the island. However I can only see that happening if there is sufficient prey there, like say reindeer or ox which live in the Arctic. And you know, the bear doesn't die before the end of the first 1,000 years.

Otherwise I like to think Iceland could be the northern equivalent of New Zealand that would be mostly populated by birds, such as puffins, geese, skuas and anything else that is found in the general region. So birds would be the best bet on who would colonise it.

The reason I'm wondering is because, unlike New Zealand, there's the potential for land mammals to reach it using ice bridges. So far only the arctic fox has done this, but could others in the future also do that?

What about arctic hares? I'm sure they could do the same. In fact I'm kind of wandering how they haven't reached there. I mean when foxes crossed over did they walk over without food cause if they did then surely hares can do the same

So this isn't a question I have for any projects but just something I thought about.

One of the bigger problems facing some species, such as cheetahs, is that their gene pool is quite restricted in diversity as they experienced a bottleneck scenario at some point; meaning if their numbers can be boosted they will suffer from genetic diseases and defects due to inbreeding. Now, could that be solved with CRISPR technology? If you can use that to alter the genome of an organism then surely you could use that to modify the genome of several cheetahs so they are more distinct from each other and when they mate their offspring will less likely suffer from defects. I understand that maybe the technology may not be that developed yet or you need to think about how to actually change their genome without significantly affecting their phenology and overall biology, but it's just something I was thinking about like if you could just alter the genes responsible for say spot number, spot concentration or coat colour shade then would that be enough?

If I got you correctly, you basically think about using CRISRP to essentially make new breeds or subspecies of cheetahs, so yeah it would work, if CRISpr works at all that is.
If a breed is genetically distinct enough, and still a same species, mixing the two would result in heterosis effect on offspring. This is used all the time in animal husbandry, since mix-breeds under heterozis effect as a rule outperform thir parent breeds. The sideeffect is that improvement is contained in F1 (first) generation, an if you cross two F1's of same mixture the features will start to dissipate to original stock. But that should work if the goal is to prevent the inbreeding depression that comes from small populations.
