We’ve only ever seen the Zylurians in Legends post-mortem, and even then they’ve always been covered with the wounds caused by “Ubuugan Fleshborers,” so we can only hope to see a healthy, living Zylurian in the flesh in some sort of upcoming piece of Canon media!
Godoan
The Godoans were most notable for their fiercely religious devotion to a mysterious machine found on their homeworld, with said machine protecting the Godo from a super virus, housing valuable, anomalous relics, and serving as a holy place of worship.
Thisspiasian
The Thisspiasians were one of the most fleshed out sentient Serpentine species in the Star Wars universe, with a rather rich history and unique customs, traditions, and practices explored in-depth in Star Wars Legends.
Zuzabol
A little known creature with an interesting real life story, the Zuzabol are a mystery just waiting to be unraveled, unless said mystery is simply part of their charm!
Tocoyan
The Tocoyans were insanely close to appearing in Return of the Jedi, but sadly are instead relegated to the void that is obscure Star Wars Legends media.
Dwuni
Similarly to how the Empire used the Wookiees or the Neimoidians had taken advantage of the Narquois, and the Pyke Syndicate enslaved this small race of aliens to work in their spice mines all across the galaxy.
Chalhuddan
This race of frog-like aliens were know for their isolationist attitude and unique “five gender” life cycle involving a complex pronoun system and random micro-metamorphosis.
Gotarite
The Gotarites claim the title of the truest “mole-men” in the Star Wars universe, often working as minors and definitely not afraid of the dark... usually.
Aruzan
Not to be confused with the Pantorans, this race of blue humanoids relied heavily on a unique form of neural technology that granted them artificial telepathy in exchange for their individuality.
Kulless
The Kulless were an odd species known for their somewhat asymmetrical appearance and potential penchant for podracing.
