Shore
The Shore is an inhospitable wasteland. Algae is available, but it’s not very nitrutious. Coconuts offer an even worse calories-to-digestion ratio.

No coconut eaters got established in the Human Garbage Dump, which means no coconut eaters got established in the River or Shore instead. The only available food is algae. The Shore is basically a small bit of Ocean biome with ⅒ of the algae. The algae-eating winner of our Ocean competition has zero speed so it cannot migrate to the Shore.
To top all of it off, predators migrate in from both sea and land.
Soonbegons migrate from time to time to eat the Detritus. Otherwise, the Shore is mostly a graveyard.

In the interest of science, I ran 10 more simulations with our submitted population. This is not to open a can of worms or to challenge the results in any way—we all knew we had to win on the first try! https://drive.google.com/file/d/1mSqaNlo5KT9l9vmY3ckd8KSTXA0xOz0u/view Some things that I observed:
The results were highly sensitive to randomness. Almost no species survived consistently.
Sometimes defenseless creatures survived and sometimes they didn’t.
LeavyTanky (ViktorThink) survived basically every time. Looks like there was no competition for the invincible leaf eater niche in the Rainforest (though plenty of leaf eaters abounded). I would say this is the strongest creature in the field of submissions based on my tests.
Usually an apex predator survived (10 attack, 10 speed). Often it was the most successful creature in terms of total energy across all biomes that it spread to. I was usually seeing antivenom in an apex predator not being worth it, but the Cheetah had it and did well in several runs.
Venomous creatures almost never survived.
As a class, armored tanks were the majority of survivors. Occasionally a speeder would survive, but much less commonly.
Usually, some mid-range tanks survived as well (~6 armor). This was often enough to stay ahead of predators while outcompeting invincible tanks.
On average only about 15 species survived past generation 1000. 30 species NEVER survived this long together. If you combine species occupying the same niche, this number was barely more than 10.
The tundra was always barren. The desert was always taken over by a single species.
I was surprised to see the Dump omnivores survive many times (Garbage Disposal, and 2-8-0 algae-...). Creatures with more than a few food sources generally didn’t do well, but the formula seemed decent in the Dump.
Sometimes the coconuts got eaten! Not often, though.
Often a 1 attack, 1 speed omnivore survived. Usually these took the place of defenseless creatures, but in one case they coexisted. It might be fun to compete to design the creature that does the best against the 555-species field. I might also do some more experiments/analysis when I have some time—let me know if there’s anything you’re curious about. Congrats to all the winners! Already looking forward to next year. Thanks lsusr for running this again this year!
Comment
Another interesting experiment would be to try to maximize the number of surviving species (starting either from the current set or from nothing).
Resolutions to my pregame prediction elicitation thingies, which I unvirtuously forgot to vote in myself:
Comment
Here’s our Brier scores for our predictions: https://docs.google.com/spreadsheets/d/1qhuACrtD0esgCqz8rQvYcZOC0I1y1l66/edit#gid=225287990 The defenseless creature result really surprised most of us. Well done, aphyer, you knew what was up.
Comment
I’m giving myself credit for a much better score than that. ;)
Edit: as per elspood’s simulations, I am revoking all of my supposed credit.
Not well enough to get more than one animal to survive, alas.
The one thing I did manage to improve my survival odds by doing was steering clear of the Tundra...even after the buff to Lichen (prior to which Tundra was mathematically impossible to survive) it seemed pretty likely that even a single non-trivial Tundra predator being submitted would inevitably wipe the whole region out. It looked like...rather a lot of people submitted distinctly non-trivial predators there.
I think it did survive in the Benthic?
Comment
The graph in the benthic article only shows up to generation 1000. Soonbegon goes extinct in the river close to generation 9000. Soonbegon shouldn’t be able to compete with the more efficient detritus-eating species in the benthic anyway.
I thought so too. I was surprised by how useful Armor was.
I reimplemented the game in vanilla Python and managed to simulate it several hundred times with ~10k random species for a total of hundreds of thousands of generations. Unfortunately, I didn’t read Hylang documentation carefully and thought foragers could simultaneously eat one of every food available, instead of just the most nutritious one... Only my throwaway locust clone survived under the real rules. :’(
In the temperate forest, the Snark is listed as extinct in generation 140 but then it appears in the table of winners. Does it mean it was reintroduced from other biomes?
Comment
Yeah. The extinction table lists the first generation in which a native species has population 0 in its home biome.

Do you have the full list of submitted creatures? I’d like to poke at it myself.
Comment
It’s here in the GitHub repo, which I have made public again.
I can’t figure out where Soonbegons are coming from. It looks like they have a population in the River for some time but then go extinct. Do they exist somewhere else that I missed?
Comment
They also survive in the Ocean sometimes.
