What unique trait identifies an albino rabbit?

The unique trait that identifies an albino rabbit is characterized by having pink eyes and white fur. This appearance results from a genetic condition that affects the pigmentation of the fur and eyes. In albino animals, such as rabbits, the lack of melanin leads to the absence of color in their fur, resulting in a pure white coat, and the pink color of their eyes is due to the visibility of blood vessels within the eyes, as there is no pigment to provide color.

Therefore, this hallmark trait of pink eyes and white fur distinctly sets albino rabbits apart from other color variations found in rabbits, each of which has specific fur and eye color combinations that do not include the complete lack of pigmentation seen in albinos.
