Zoe is Oreo's filly, born 9-16-98 on the Island of Molokai before we could
move Oreo to our sanctuary. She is extremely rare.
Her unusual color is due to her having "amelanosis". She is not an albino.
She has striking gold stripes and blue eyes. In horses, there is a similar
condition called "Lethal White Foal Syndrome" which is associated with the
occurrence of other serious birth defects. Although this color variation
occasionally occurs in wild herds, the animals would likely survive only a
few days at best. This is probably because zebras use their stripes as
camouflage to blend in with the rest of herd. This then allows the herd, to
confuse predators with the changing patterns formed by the movement of a
large group. Animals that stand out from the herd are easy targets for
predators. In nature, having a color variation that makes you stand out is
not a good thing!
There have been reports of at least two other "white" zebras in captivity.
One in Germany about a hundred years ago and another at a zoo in Tokyo in
the 1970's. At this time we know of only one other zebra like Zoe alive. If
anyone has heard of other "white" zebras, we would be very interested in
hearing about them.
Although Zoe may have health complications as she ages, for now we notice
only poor night vision. Because we are concerned about other health problems
she could have (for example, kidney problems), we feed her a low protein
diet and monitor her for signs of sunburn or skin cancer. As with our other
non-endangered animals, she will not be bred. | I***i
