The shamunaar, hailing from the legends of Roon, was an immense saurian with an elongated neck. Existing within Roon's muddy terrains, it posed a persistent danger to the planet's wild banthas.
Typically, the shamunaar would enter hibernation periods that could stretch for decades at a time, but external disturbances could rouse it from this state.
There was a prevailing theory suggesting the shamunaar wasn't originally from Roon, instead being an introduced species.
The spelling "shamunaar" appears in resources such as The Essential Guide to Planets and Moons, Geonosis and the Outer Rim Worlds, and the Databank. However, The Complete Star Wars Encyclopedia presents a different spelling, "chamonaar," for the creature's name, while using "shamunaar" to refer to the frigate of the same name. This article operates under the assumption that the more common spelling is the accurate one.
