Massiff

Massiffs were reptilian creatures found on Geonosis and Tatooine. The species' original world was unknown; however, the Geonosis and Tatooine populations were by far the most numerous. Canine in appearance with an armored hide, the beasts could be domesticated and used for sentry and guard tasks. On Geonosis, possession of a massiff was a sign of authority and aristocracy. The Geonosians and massiffs had a somewhat symbiotic relationship; in exchange for shelter, the creatures would rid the hives of pests. It was easy to tell the age of a massiff, for they grew a new pair of antlers every standard year.
