A creature similar to a Maravel dragon
A Maravel dragon was a dragon-like creature native to Maravel.
A specimen in the collection of the Lactra VII zoo in the rainforest environment was said, by James T. Kirk, to be similar to a Maravel dragon. (TAS: "The Eye of the Beholder")
The Maravel dragon-like creature, Swooper, and the mechanized sentinel all use slightly modified versions of the same set of animations.
