Krillcrabs, a form of edible crustacean, provided meat for consumption. Temmin Wexley, a junk dealer, was reminded of krillcrab flesh when he observed the light-colored limbs of an Uugteen through gaps in its armor on the planet Akiva; this occurred not long before the Rebellion on Akiva, and the image evoked a krillcrab turned upside down, exposing its edible parts.
The initial reference to Krillcrab appeared in Chuck Wendig's novel, Aftermath, which debuted in 2015.
