Radanks were non-sentient predators in existence by the year 27 ABY, during the Yuuzhan Vong War, when the Yuuzhan Vong invaded the galaxy of the New Republic. Radanks possessed clawed limbs and a proboscis, and Yuuzhan Vong Warmaster Tsavong Lah even replaced one of his arms with a grafted radank leg in a show of devotion to his gods during the war. In 40 ABY, after the war was over, at least one radank hunted in the undercity of the planet Coruscant.
