Gralloc

"Grallocs are simply a cousin species to mynocks. They live in vacuum, they attack power cables and couplers&mdash;" "They’re also considerably larger and tougher than typical mynocks."

- Director Orson Krennic and Grand Admiral Savit

Grallocs were a species of creature related to the mynock. They were able to live in the vacuum of space, attacking power cables in a similar way to mynocks, but were larger and stronger. Imperial governor Haveland faced issues with grallocs in the Esaga sector, as did Director Orson Krennic at an equipment transfer point for Project Stardust.
