"Lean, amphibious bipeds with a tendency to travel in packs, lurkers are carrion eaters most comfortable in tropical environments. Alone, they usually avoid confronting danger, crawling into tight spaces and observing potential threats from a distance. In numbers, they can strike with a rabid, frenzied intensity, happily downing prey for later consumption. Biologists serving the Hutt Cartel believe that lurkers originated on a nameless jungle world on the edges of the Torch Nebula. They were first identified in the wider galaxy two hundred years ago, and have begun appearing on more and more worlds ever since. No convincing explanation for the lurkers’ spread has been offered, leaving the creatures a disturbing mystery."
