This phrase refers to a specific color variation of the Petaurus breviceps, characterized by predominantly dark fur. These animals, like their more common counterparts, are small, nocturnal marsupials known for their gliding membrane extending from their wrists to their ankles, enabling them to move efficiently between trees. The dark coloration distinguishes them visually from the more typical grey or brown varieties.
The allure of this color morph stems from its relative rarity and striking appearance. This can translate to a higher market value within the exotic pet trade. Historically, color variations in animals have often been selectively bred to enhance certain traits, and this is likely a factor in the propagation of the dark-furred variety. Understanding the genetic basis of this trait is important for responsible breeding practices and conservation efforts.
