One of the species closest to Humans, the Sorrusians were set apart almost exclusively due to their flexible, compressible skeletal structure.
Toma
The Toma were almost drawn into the clone wars due to CIS moles in the Republic, but thankfully they were spared this fate, or so we think.
Sernpidalian
The Sernpidalians are by no means the most remarkable or memorable species in Star Wars, however they did play a major role in a key Legends event: the death of Chewbacca.
Shahkirin
A lesser known species of the Resistance, the Shahkirins are still rather mysterious, but thrived in dark, cramped spaces which may be an indication of their homeworld environments.
Devlikk
Possessing some of the shortest lifespans of any known sentient species, this bird-lizard-dog-rat race had a rather complex and depressing history.
Benathy
A massive species from an unknown world, the Benathy valued strength and power, something both Darth Vader and Kylo Ren were more than able to demonstrate to them.
Yahk-Tosh
The Yahk-Tosh were cousins of the Hutts, and clearly attempted to follow in their criminalistic footsteps, often to varying levels of success.
Aeosian
One of the few original species introduced in the Star Wars Resistance animated series, the Aeosians have a fairly unique real life origin, and a tragic story within Star Wars Canon.
Ardennian
One of the many four-armed species in the Star Wars universe, this simian race had a surprisingly predominate role in the live action film, Solo: A Star Wars Story.
Onodone
A mysterious race of aliens most likely originating from the Unknown Regions, this species was most well known for their secretive natures and massive snouts.
