The cinnamon sugar glider represents a beautiful color morph of the common sugar glider (Petaurus breviceps), characterized by warm brown tones ranging from light tan to deep cinnamon-brown on the dorsal surface with cream or white undersides. The scientific name Petaurus derives from Greek "petaurus" meaning acrobat or rope walker, while "breviceps" combines Latin roots meaning "short-headed." All sugar gliders regardless of color belong to the family Petauridae, which includes several gliding possum species native to Australia, New Guinea, and surrounding islands.
In breeding communities, cinnamon sugar gliders are sometimes called "brown gliders," "tan gliders," or simply "cinnamons." The cinnamon coloration results from a recessive genetic mutation affecting melanin distribution and density in the fur, creating the characteristic warm brown appearance. This morph differs from the wild-type standard grey coloration which features grey backs with black dorsal stripes. The cinnamon gene dilutes the black pigmentation to brown tones while maintaining the cream or white ventral coloring.
Various shades exist within the cinnamon designation, ranging from very light tan individuals (sometimes called "light cinnamons") to deep, rich cinnamon-brown specimens. Breeding two cinnamon sugar gliders produces cinnamon offspring, as the trait is recessive. When bred with standard greys, offspring appear grey but carry the cinnamon gene, potentially producing cinnamon joeys in future generations when bred with other carriers. Some breeders have developed combination morphs such as "cinnamon leucistic" or "cinnamon platinum" by combining multiple color genes.
Sugar gliders earned their common name from two distinctive characteristics - their dietary preference for sweet saps, nectars, and sugary foods in the wild, and their remarkable ability to glide between trees using the patagium membrane extending from wrist to ankle. In their native Australia and surrounding regions, various indigenous names exist in Aboriginal languages. In the pet trade worldwide, color morphs are designated by adding descriptors like "cinnamon" to the base name sugar glider, helping identify specific breeding lines and genetic traits.
