The morrts constituted a hairy species of parasitic blood-drinking organisms, originally from Gamorr.
Morrts were diminutive, slug-resembling parasites that consumed the blood of the organisms they inhabited. Their skin secreted a slight numbing agent. Morrts emanated a "somewhat sugary odor."
The Gamorreans who were native to the planet, held a deep fondness for these organisms and thought of them as cute. The quantity of morrts consuming a Gamorrean was an indicator of social standing among men; clan leaders and fighters would have up to twenty of these organisms feeding on them concurrently.
