I'm writing a whole Post-Apocalyptic Series that features different species. While I'd perfer to not give the details of the whole plot[It would take a very long time], I'll give some details to understand, hope you enjoy my lore.
First, The Ebola Dragons, No, They don't have Ebola, They're called that because they're evolved lizards that came from the Ebola River in Africa. They're mainly now colonizing the ruins of Western Europe After Driving out "The Ministry"[Again, long story, but just think The Enclave from Fallout if it was run by SJWs and wanted to spread Neo-Liberalism] They're a bit more like Drakes or Draconians in that they're not massive like actual dragons[Though, They tend to be rather large. being 5 feet is considered the size of a runt for them and a lot of them grow to being 10 or even in rare cases 20 feet tall] and they walk upright. they do tend to fly however.
Other Details include that they tend to be fast learners, fast runners and swimmers[though their swimming isn't as good as their flying or running], and usually strong immune systems, even being able to resist radiation.
Next up, The AquaPhiles[Which are heavily, but loosely based on "The Deep Ones" from The Cthulhu/Lovecraft Mythos]. As you can guess They are a race of fish-like beings. They Began as an experiment in Mexico. Scientists were testing to see what would happen to generations of fish if they were given human D.N.A.. The fish rapidly evolved human-traits with each generation. from simply the ability to survive outside of water, to more human like features and sizes[hands, noses, teeth, legs, for example], and later even human-like intelligence and the ability to comprehend language.
Aquaphiles had a violent breakout from their labratory, with huge shootouts between armed mexican forces, they eventually fled to the oceans to make their own cities, hidden from the public eye.
Along the way, they also somehow came into the knowledge of a being known as "Yul'Floggonoar" [FYI, Like The Ministry, It would be long to describe Yul'Flog himself, but Basically Just think of an Eldtritch Abomination that looks like a mixture between a Mushroom and a Jellyfish]. Many aquaphiles became cultists to Yul'Floggonoar, worshipping him like a god and praying for him to sink the land into the sea, which would give their race complete power over the rest of the world. Religion Aside, Aquaphiles have no concept of Government, and are generally "Anarcho/Tribal-Capitalism", Think Rapture but if Andrew Ryan didn't ban Religion due to converting to the Cthulhu-Cult and it Didn't get destroyed due to everyone becoming addicted to a Super-Power Drug.
Speaking of Not having a Concept of Government, most Tend to not Have Concepts of Morals or Usually have a very, very basic form of it. though some are more moral than others.
Before the Apocalypse, the Aquaphiles tended to also raid ships around the Gulf of Mexico and Sink Them. Usually to give the Crewmembers as Sacrifices to Yul'Floggonoar and For the Cash provided from their goods and scraps from the shipwrecks, even after the end they still tend to raid ships manned by crews of survivors[though a lot of those survivors do tend to be pirates, so It's not always innocent lives that are taken]
So those are two species I've made, hopefully you'll be able to enjoy them more when I actually release this series I'm talking about. there's more than these two but the others are either not as interesting or require a lot more explanation
