The zabathu was a riding animal native to Andoria, similar to a Terran horse.
Simulations of this animal were available on file in the USS Enterprise-D holodeck. In 2365, Jean-Luc Picard rejected it in favor of a horse. (TNG: "Pen Pals")
"Zah-BAH-thu" was the pronunciation for this animal's name from the script pronunciation guide.
