diameter. The sarlacc uses its four legs to anchor itself underground. Astrophysicist and science fiction author Jeanne Cavelos compares the sarlacc's hunting method to that of the antlion. The sarlacc's mouth also has similarities with that of the lamprey. Because most sarlacci inhabit isolated environments and rely on prey to stumble into their pit, they rarely feed; the digestive system dissolves prey into nutrients over a period of several thousand years. If no living prey is available, a sarlacc relies on its root system to absorb nutrients. One sarlacc located on an airless moon feeds on cometary material rich in oxygen, hydrogen, carbon, and nitrogen. The sarlacc's stomach is lined with vessels that attach themselves to a swallowed victim and maws for quick digestion or breaking apart of large prey. The maws close when exposed to bright lights. The stomach also contains neurotoxins, which induce hallucinations in prey which "suggest that the sarlacc somehow absorbs the intelligence of all its victims, who live on in disembodied torment". A sarlacc can communicate with its victims through this stolen consciousness: In one Star Wars short story, an unnamed Jedi explains that "sarlacci do interesting things with messenger RNA: over the course of millennia, they can attain a sort of group consciousness, built out of the remains of people they've digested. I talked to such a sarlacc, once a few decades ago". In the anthology Tales from Jabba's Palace (1995), edited by Kevin J. Anderson, Dan'l Danehy Oakes's story "Shaara and the Sarlacc: The Skiff Guard's Tale" is told by one of Jabba the Hutt's soldiers, who tells Boba Fett that his sister Shaara and her Imperial stormtrooper captors were thrown into the pit, whereupon the sarlacc swallowed the stormtroopers, but expelled Shaara, for reasons unknown. In the short story "A Barve Like That: The Tale of Boba Fett", by Daniel Keys Moran under the pseudonym of J. D. Montgomery, Boba Fett struggles to free himself from the belly of the sarlacc. As Fett is digested, the creature converses with him mentally in the voice of an alien named Susejo, eaten by the sarlacc four thousand years earlier. Having caused his jet pack to explode, Fett uses a concussion grenade to blast himself free. Years later, Fett is recognized by the sarlacc upon approach.
