Vulcan marsupial

The Vulcan marsupial is an animal native to Vulcan.

When The Doctor from the USS Voyager was trying to find a cure for his creator's illness, Doctor Lewis Zimmerman manipulated The Doctor's tricorder so that it would display a mitochondrial scan of a Vulcan marsupial. It took The Doctor a full hour to find out what was wrong with the scan.
