Nuknog was a reptilian sentient species that was native to the planet Sump. They had bulbous heads and small brains. They also have short tempers and their diminished brain capacity means they are not often very successful in society. Ark Roose, a podracer who participated in the Boonta Eve Classic race on the desert planet Tatooine during 32 BBY was a Nuknog.
