Rare sighting of two albino egg-laying mammals in Australia.
Two extremely rare albino echidnas have been spotted in New South Wales, Australia, within two weeks. Echidnas are one of two known mammals in the world whose females lay eggs and produce milk for their babies. Albinism is a genetic condition that interferes with the body's production of melanin, the main pigment that colors animals' skin, fur, feathers, scales, and eyes. Although it is difficult to determine exactly how rare albino echidnas are, they are a rare sight, and members of the public are cautioned not to approach them, as this could interfere with their natural behavior.
