Granite slug/Legends

"Those Vulkars are dumber than a Coruscant granite slug! The slug looked like fungus not much is known about it."

- Canderous Ordo referring to the Black Vulkars

The granite slug was a silica parasite native to the planet Coruscant.

Biology
This small terrestrial mollusk left a corrosive acidic slime wherever it traveled. It consisted of four eye stalks, two mouths, one foot, lung filaments, and suction pseudopods. They were gray/green in appearance.

History
Granite slugs were introduced to the planet in an attempt by the Galactic Republic to clean up garbage that existed in the lower levels of the city. The large amount of food materials resulted in a rapid growth in granite slug population, which resulted in increased 'cleanliness' in the city but also resulted in a population increase among the predator populations as well.
