The Karkarodons were a species of sentient aquatics native to the planet Karkaris. Some, like Riff Tamson, supported the Confederacy of Independent Systems during the Clone Wars.
Karkarodons had tall bodies with webbed hands and feet. Their shark-like heads had pointed noses, slits, and many rows of razor-sharp teeth.
In 21 BBY, during the Clone Wars, Separatist Commander Riff Tamson led the Confederacy during the Battle of Mon Cala. Later, another Unidentified Karkarodon was shown at the Republic Judiciary Central Detention Center who provoked Rako Hardeen (Obi-Wan Kenobi in disguise) and got his hand stabbed with a fork.
