The book provides information on 180 species from throughout the Star Wars saga, drawn from sources both well-known and obscure. Each species is also shown along side three other species to show appearance and comparison in size to others. A web enhancement named Ultimate Alien Anthology Web Enhancement was later released, describing two additional species.
From the Outer Rim to the Galactic Core, countless different species populate the galaxy. While most members of each of these alien races share similar characteristics among every species—from Geonosians and Jawas to Clawdites and Krish—great heroes and despicable villains can be found.
A Caamasi, Caarite, Cathar and Celegian
This source book contains information on both the alien species listed and the new Prestige character classes, making it useful both to players of the RPG and those who merely want information on the Star Wars universe.
