Arkanian dragon
From Wookieepedia, the Star Wars wiki.
The Arkanian dragon was an avian reptile native to Arkania. They were intelligent enough to be semi-sentient. They are known for their lightning-fast strikes, which Master Arca Jeth used to instruct his students, Ulic and Cay Qel-Droma, and Tott Doneeta in the ways of lightsaber fencing. This dragon could fly up to 3,000 meters at speeds of 140 kilometers per hour. They eventually died off for reasons unknown, although there have been rumors of sightings throughout Arkania.
