The Grumpackian tortoise is a species of reptile.
The average life span of a Grumpackian tortoise is twelve thousand years, making the animal the longest living organic lifeform in the Milky Way Galaxy. They are also slow animals, as it would take a Grumpackian tortoise fifteen thousand years to circle Deep Space 9's Promenade. (DS9 reference: Legends of the Ferengi)
