Looks like chimpanzees...

I think it's an old TESB concept, but don't quote me on that...

"Alien 23", the thinker, was given a second life as Brangus Glee from Dor Nameth. While his species name was not confirmed, a suspiciously similar looking Dor Namethian alien (as the character Lexo Sooger) was introduced in Episode 8.

A cross "between a lobster and a reptile", this "Alien 25" was named the Lobel. These creatures from Quesh would later be featured in the SWTOR video game.

"Alien 25", a probable candidate for Jabba's aide, was turned into Soth Petikkin, a native of Tefau. His species name was revealed as Tefaun in the 2013 blog post "Viva Space Vegas! The History of the Marvelous Wheel" on the official website.

The "alien with the beaklike snout" is Neb Dulo, a Tocoyan from Tocoya. This species also appeared in the SOTE Evolutions comic, but wasn't named until the Essential Atlas came out in 2009.

This "possible rhino / elephant head" became known as Bron Nurs from Nentan (where Bren Derlin was also born), but his species was never named.

"Alien 18" was used by the CCG to depict the horned Makurth, a carnivorous species from Moltok (which also served as the Ho'Din homeworld).

"Alien 18" was a one-eyed species that was introduced as Niado Duegad from Vodran. His species is sometimes referred to as Vodranite, but never officially confirmed.

The Rishii are also often portrayed as owl-like beings, although some media have them resemble raptors.
