Karkarodon

The Karkarodon were an amphibious aquatic species that originated on the planet Karkaris. The species were known to be fast swimmers, often ripping apart their enemies with their teeth. Separatist Karkarodon commander Riff Tamson was depicted taking multiple blaster shots to the chest without showing any signs of injury. Another Karkarodon was also imprisoned in the Republic Judiciary Central Detention Center around 20 BBY.

Behind the scenes
The appearance of the Karkarodon is based on sharks. The name of the species is a reference to Carcharodon, a genus that includes the great white shark. Their homeworld, Karkaris, also has a name similar to charcharias, which is the species name for the great white.
