Whose the oldest Star Wars species?

A few months ago author Paul S. Kemp asked on Twitter what some really old Star Wars species were. Ever since then the question has plagued me. Why? Cause I'm an obsessed Star Wars fan when it comes to aliens and stats.

One of the first species to come to mine is whatever the heck Yoda is. But that's actually problematic when you look at it because he was a Jedi and Jedi members of any species typically live 2-3 times longer if they aren't killed. Since Yoda was around 900, his species probably only lives to around 300-450.

Wookiees also come to mind. And let's not forget the Old Jedi Masters who popped up in Legacy: Whiphids + Neti.

It's certainly the beginnings of a good list, however, I've done some digging in Wizards of the Coast source books and found the following in The Ultimate Alien Anthology. (10 oldest species in the book)

300+ Tchuukthai
301+ Abyssin
400+ Berrites
400+ Feeorin
400+ Wookiee
501+ Shi’ido
781+ Draethos
926+ Hutt
951+ Anzat
4000+ Neti

I found a few more in other books, but I don't have the stats with me right now. I'll post them later. One species I found the stats for that is a good contender is the Gen'Dai (Durge). If you can think of any (especially if you have sources) let me know.

Gen'Dai are a good candidate because their whole biology is based on regeneration. Aging is, after all, the gradual damage and destruction of your cells, usually by harmful Free Radicals. If one could replace damaged and destroyed cells within minutes or hours of their destruction (as Durge seems to be able to), then he could live as long as he had at least some body mass left. Alternatively, it might be that his regeneration requires the survival of a specific cell type, perhaps located in one organ or several nodes (I'm thinking like how plants have some sort of stem cell at key points, to allow for easy differentiation into root, stem, flower, etc.), and so at least some of those stem cells must survive.

All that to say, as long as a Gen'Dai still had at least some [appropriate] cells, he could regenerate fully, regardless of his age.

Has anyone else here read the Marvel Civil War? I've been reading through it, and there's a story where Wolverine hunts down Nitro (who explodes; it was his explosion that killed a bunch of kids, which made the public want to Register superheroes). Nitro explodes with Wolverine next to him, and all the soft flesh was burned away, leaving only an adamantium-coated skeleton. But Wolverine survived, being able to fully regenerate from the bone marrow under the Adamantium.

It was my understanding that Anzati were supposed to have an immortal lifespan.

I've also read the Muun have human lifespans, but Luceno implied that they had extraordinarily long ones in Millennium Falcon, I believe.

Edit: "To Hutts, Wookiees, Muuns, and a handful of other species, ninety-three years barely put one past adolescence..." It's toward the beginning of chapter 9.

I always thought Luceno put that it for Plagueis, as he intended Plagueis to be the reigning Dark Lord of the Sith for a long time.

DIGRESSION ALERT:

Plus Drongar was discovered by Nikto scouts 220 BBY, and was the only place in the galaxy that one could find bota, which Darth Ramage -- claimed to be a Sith scientist -- used to discover a way to augment one's connection to the Force. I always speculated Ramage was Plagueis' master given his description as a Sith scientist and the timeline basically requiring him to be a Banite Sith.

You must also take into effect the advances in medical technology in that society. It wouldn't surprise me if non-jedi humans lived for 200+ years.

I don't know if they count, but I was under the impression that the Oswaft and the species Vuffi Raa belonged to (both from Lando Calrissian and the Starcave of ThonBoka) where both quite long lived (if not ancient).
But I don't recall any exact ages being given in the book.

There is also the Star Dragons, too.

Yeah but how smart are they? They're more of a creature than a sentient species.

I was thinking the other day that the Croke might be a good candidate for the oldest. Gepta was over 20,000 years old and Wookieepedia makes it sound like all of their species was Force sensitive.
