Duracrete slugs were a species of non-sentient slug found in the underworld of the planet Coruscant. They fed on the artificial stone duracrete, then after digesting it, secreted it from their bodies to form a hard outer shell. The creatures used a series of mouth tentacles to sense their surroundings and could grow up to ten meters in length.

Biology and appearance[edit | edit source]

The duracrete slug was a species of non-sentient slug that fed on duracrete, a type of sturdy[1] artificial stone that it could break down with its abrasive and muscular mouthpart.[2] Though born with soft skin,[3] the slugs would digest the duracrete, then secrete it through their skin[2] or excrete it to form a hard outer shell[3] of armor-like skin.[1]

As its underdeveloped eyesight was all but useless, the duracrete slug's main sensory apparatus[2] was a series of tentacles around its mouth[1] that served as feelers[2] to sense its surroundings. The slug's armored skin was tan in color, while its two small eyes were black. The body of an adult slug could grow up to ten meters (thirty-two feet, eight inches) in length and was covered in a series of spiked ridges that ran from the creature's mouth to its tail.[1]

History[edit | edit source]

Duracrete slugs were one of several unique forms of wildlife that evolved on the planet Coruscant due to the thousands of years of urbanization that resulted in the world becoming an ecumenopolis. Adapting to incorporate the artificial into their biology, they fed on the duracrete used in the construction of buildings in the Coruscant underworld and came to pose a threat to the area's structural stability.[2] Exterminators on Coruscant carried pest control equipment to eradicate duracrete slugs.[3]

Behind the scenes[edit | edit source]

"The duracrete slug is a species-shift from the slug in the Wildlife of Star Wars book by Terryl Whitlatch. The slug is based on her design, but with a twist -- instead of having a soft/slimy skin, it has an armored skin developed from consuming and excreting duracrete, so that they're really tough -- and big."
―Robert E. Barnes[src]

The duracrete slug was based on a sketch of a duracrete worm by Terryl Whitlatch.

In the new Star Wars canon, duracrete slugs were first mentioned in the 2015 reference book Star Wars: Absolutely Everything You Need to Know.[1] The species was originally created by concept sculptor Robert E. Barnes in collaboration with author David West Reynolds exclusively for use in the 2002 Star Wars Legends reference book Star Wars: Attack of the Clones: The Visual Dictionary.[4]

Barnes created a sculpture of the creature to be photographed for the book based on a sketch of a duracrete worm created by concept artist Terryl Whitlatch for the 2001 Legends book The Wildlife of Star Wars: A Field Guide. Barnes shifted the design to have armored skin rather than soft skin based on the idea of the creature exuding duracrete.[4]
