Araneo isn’t a single species, it’s actually the scientific name given to spiders, so you’re right about the Ark creature not being real, but pulmonoscorpius was actually a real species, the version in Ark is just genetically modified and quite a bit larger than real pulmonoscorpios. So you could say the Ark version isn’t real but pulmonoscorpius is real. I’m tired of typing pulmonoscorpios now, I don’t even know if I’m spelling it right lol. And the onyc is real, it’s proper name is Onychtericterus (I think…). I don’t know if the Ark version is accurate or oversized though.

I hoped this helped clear things up, and I’m sorry if I sound a bit rude, I don’t mean to be.
