I must have mistakenly assumed the Greengill's shell was soft and accordion-like, because it was nearly the same color and lighting as the rest of its body. The Greengill's ancestors, though, make this clearer.

I believe I made the shell region very long: it doesn't have a segmented body and tail so much as it stands on its head. (Barnacles are weirdos, too.) It wouldn't be too hard to modify the Greengill art so it has a thin shell with big flexible segments.

In some of the Pedesorms, the art is ambiguous enough the eyes can be changed, or the descriptions can be changed without changing the art. However, Cube67's idea of using both photoreceptors and chemoreceptors on the bulbs of the antennae would be easier.

What would stop them from instead leaving the colony and trying to become the harem of another, unrelated female? It would seem there's a protocol of sorts for reproduction-capable Gamergate Gundis: "Losers, instead of being killed, will simply leave the colony followed by their own supporters and start anew."

There's still the "haram" typo.

Her harem reliably losing the will to live and starving is odd and seemingly maladaptive. Certainly, birds which mate for life (more or less), can appear deeply emotionally affected by the loss of a mate, and may end up dying within months afterward, but this species' description suggests losing the will to live always happens. Do they bond really, really strongly? Do they actually desire being with her more than eating, and so keep looking for the now-dead gamergate and get stuck in a neurological loop of prioritizing that over everything else? Do the fertile females emit some kind of appetite-inducing chemical, and the harem's ability to muster up an appetite atrophies while she is alive?

In a scientific name, only the first name, the genus name, is capitalized. The names of organisms, at least in the diet list, should be capitalized. The reproductive methods should also be capitalized.

You missed some errors I pointed out, such as: "its claws like stingers"

The supplementary art doesn't have visible gills.

I don't recall any other organism art where an organism bleeds red blood. (My art of a Dualtrunk getting pestered by Bloodbees has shallow scratches with green blood, but it's not so violent as this.) This could be shocking content. And yet, dinosaur books intended for children can still illustrate a Tyrannosaurus chomping down and causing bloody holes, and logically the Imperial Quid would kill its prey in a bloody way.

Should there be a read-more for that supplementary image on the wiki? Should the bleeding be reduced?

The name, scientific name, creator, ancestor, habitat, size, diet, and reproduction information should all have only a single return (line break) between them, or at least a consistent spacing scheme. The organism names, habitat names, and reproductive methods should also be capitalized.

The name here is listed as "Angels of Death", but that plural name would only make sense for a genus group or if "Angels" was supposed to be both the plural and singular, like "deer" and "sheep". I would recommend "Angel of Death" be capitalized, like most species, although there has been an accepted habit of not capitalizing species names on the Beta timeline.
Of course, these points could be irrelevant: "Angel of Death" is a very odd name to give an organism. There's the Monkeypuzzle Tree, pineapple, Adam's rib/ribs of Adam and St. John's wort, common kingslayer (a jellyfish that was named someone with the surname King) as examples of organisms with odd, spaced-out or referential names, but "Angel of Death" is so vague but well-established as phrasing it doesn't make sense to use it. "Deathangel" or even "Death Angel" is closer to conventional Sagan 4 organism names. (Not to be confused with the Angel Dart, a Dartirs descendant inspired by the Zoraptera, or "angel insects")

"Waters edge" should be "water's edge". ("Waters' edge" also makes sense, though it sounds antiquated.)

"Victims flesh" should be "victims' flesh" or "victim's flesh". I would recommend not using informal, colloquial language like "throw their weight around"; I recall Hydromancerx once revised the phrasing of one of my organisms from "bite first and ask questions later" to "bite first, and spit out if not edible". (Delivering the occasional joke or describing something funny with detached humor is fine, though.)

"almost doubling" should be "which has almost doubled". "and enabling" should then be "and enabled".

"Quids body" should be "Quid's body".

"warns hunters" should be "which warns hunters". "One of the[...]almost invisible" should be chopped up into two or three sentences.

"with very large eye" "It has also adapted[...]rest of its body visible" I'm not sure how to chop up that sentence. The end of the sentence, ending with "body visible", should have a period at the end.

Make sure you edit the picture to indicate it has gills.

While I've many tiny artwork before myself, I do recommend you adjust the size of the art to be a little bigger. As it is, it's hard to see that red dot on its face is its smaller eye. (Although you did mention that detail in the description.)

Generally, depictions like the lower one, in which it is attacking prey, is included as a supplementary image. (See the Oilyback entry or Seashrog entry for examples of supplementary images.)

"claws like stingers" that should be "claws, like stingers" or "claw-like stingers".

I hadn't said anything yet because I wanted to look over the biology of the organisms first, but I suppose it's a moot point now.

"exponentially in size" Are you sure you mean to use that word?

Is "fat, hairy sausages" becoming some kind of textual meme?

" their life." That suggests the singular "they", when "their lives" makes more sense.

" Similar" A word's missing. "Similar behavior", perhaps?

I like its art and concept design. I also like how the displays are adapted to echolocation.

Oh, I like this genus group.
But...those integrated species are all extinct already. Its ancestor is extinct, too. Rustmolds are still around, though, so you could tweak the art and description and explain they don't form plasmodial structures anymore.

Verdiundis are not Dundis, because they are not descended from the Yellowdundi.
It's a very interesting "fungus". I like how their reproduction is distinguished from mushrooms.

These are adorable and unique.
Can you elaborate on "Vermees and co."?

Is its left hind foot really that far apart from its right hind foot, or is it lifting it up?
It's interesting to see the distinct, grotesque Nergali style applied to a marsupial-esque Shrew.

Don't you mean "Rundi"? It's descended from the Verdiundi, which itself isn't closely related to the Yellowdundi, and therefore the Sitting Dundi or Handlicker Dundi.

"which will lose their will to live and starve once the gamergate dies to ensure there will be no inbreeding when a new gamergate is chosen." That seems rather vague. Breeding males of the entire species reliably losing their will to live ("give-up-itis", I believe, is the medical diagnosis) does seem odd to guarantee. Breeding males being especially prone to takotsubo syndrome brought on by the stress or even heartbreak of the gamergate dying and then killed when they have a near-heart attack does make more sense.

"haram" should be "harem"; "haram" means "forbidden by Islamic law".

Would these really be entirely global? I don't think they would be well-suited for tundras, glaciers, or other very cold environments.

The purple one on the right doesn't have a scar on her throat. Should it be assumed that's a gamergate sample? It does seem to have a bigger throat, but it's so subtle I had assumed it was a different body fat distribution at first.

I don't like the making of groups willy-nilly, but its ancestor did exist in 14 habitats, and its diet means it wouldn't need to become locally adapted as much as usual. I can't think of any reason why they wouldn't be a genus group.

You put grass on the clouds. (What.)
I'm just imagining trying to explain this. "Yes, on Sagan 4 (Alpha Timeline), grass can fly, it grows on clouds, and also it's purple."
What's next? A bird in the dirt? (Not that hard to do, since there are probably penguin/duck-esque Sindohve relatives that would be easy to adapt into burrowers.)

I like the shading effects.

This is very interesting. It would seem to be generic seagrass from a distance, but it's so much more interesting than that.

This one has a lot of potential. I'm already thinking of some locally-adapted Hockel and Gumjorn species. The artwork is beautiful, too.
Where is it, specifically? Is it near the Solpimr, Negative, or Nemo sea mounts, or in the middle of that gyre?

" all-you-can-eat buffet" does sound rather informal.

Between Seashrogs and these, there might be a big Great American Interchange-esque extinction event as organisms spread around the world.

If Nergali made the lineart, shouldn't this be noted as a collaboration, or at least credit Nergali in the submission?

How strange: it's a grotesque, bloated creature with small eyes and it's not made by Nergali. If it wasn't for that really good rock and sand, I would believe Nergali made the art.

"members Vomex genus." Members of the Vomex genus.

"non related" should be "non-related".

"After several generations" you should specify "generations" as in "millions of years". Otherwise, it might seem as if one Baṛādohve's great-grandmother is a definite Hemodohve.

"unifested"You mean "unifested", right?
"subcarangiaform" should be "subcarangiform".
It's interesting to see so much light within the water table. I like the art.

What an endearing little not-fish.
I wonder if "subcarangiform" is the most popular style of swimming in Sagan 4?

Are these meant to be similar to filamentous bacteria? (see here, at the bottom)

"they shave" should be "they have".

"As cellular parasites, they shave a much more simplified their cellular structures,[...]"
Did you mean: "As cellular parasites, they have greatly simplified their cellular structures".

"They have no centralized nucleus," You surely meant to use a semicolon or colon.

"Once they have successful entered" should be "once they have successfully entered".

"high jack" is a typo; you meant "hijack".

"oasis" should be in the plural, as in "oases".

It seems its ancestor's lifestyle was similar to a Vampyrella, an amoeboid protist with many long pseudopodia that sucks out cellular contents.

"Insead their nasal passageways have widen"
That's a typo. It should be: "Instead, their nasal passageways have widened".

EDIT: None of their prey live in Dixon Dunes.

Is there a reason its ears are proportionately smaller? Are they likely to be damaged in its environment, or make it less aerodynamic?

Is it indeed slightly less furry than its ancestor?

Cheetahs and other cursorial predators don't need hooves or "proto-hooves", but perhaps you were basing these off more obscure animals, or combining animals of different physiologies. Were you inspired by hoofed crocodiles.?

The Quaxaca is a brocoli-dandelion plant, not a fauna. You'll have to mention it's an omnivore, or eliminate the Quaxaca from its diet.

"Little more than a tiny green sphere, and those that grow atop are readily dislodged by gusts of wind, which aids in their dispersal."
You surely meant, "they are little more".
These probably form a unique landscape, in the aggregate. Tiny fauna in the mountains of the Dixon-Darwin super continent would have very good reason to invest in chitinases.

"environemnts" was the problem. It's a typo. You meant "environments".
