Dathomiri rock dragons, also known as rock dragons, were a type of reptile that naturally occurred on the world of Dathomir. Their hide was coarse and patterned, providing effective camouflage within their environment. As cold-blooded reptiles, these creatures reproduced by laying eggs, requiring them to incubate their nests to maintain warmth. While their diet primarily included vegetation and insects, rock dragons possessed a potent venom delivered through a stinger, used for defense. Remarkably, this venom was potent enough to kill even a mature rancor. Despite their diminutive size and seemingly delicate form, these creatures were deceptively dangerous.
Tenel Ka Djo chose the name Rock Dragon for her personal starship originating from Hapes. Her rationale was that ships from Hapes often bore the name "dragon", and since she had encountered a rock dragon on Dathomir during her childhood, the name served as a tribute to both aspects of her heritage.
