Albino Koala
Meet Onya-Birri, the amazingly cute koala who joined the San Diego Zoo in 1998. He was the only albino koala available to the public in a zoo, and his name is an Aboriginal word for “ghost boy”. “We had no idea that either of Onya-Birri’s parents carried the recessive gene for albinism,” admitted Valerie Thompson, associate curator of animals.
