Why this wallaby lacks normal coloration fur?

The wallaby may lack normal coloration in its fur due to a genetic mutation, which can affect pigment production and result in a lighter or altered coat color. Additionally, environmental factors such as diet or exposure to sunlight can influence fur coloration. Health issues, such as skin conditions or parasites, might also lead to changes in the wallaby's fur appearance. Lastly, some wallabies may exhibit color variations as a natural adaptation to their habitat.
