Zebras have striking black-and-white stripes. They boast one of the most iconic coats of the animal kingdom. Sometimes, a zebra is born that doesn't fit the striped mold. Antony Tira is a tour guide and photographer. He works at the Masai Mara National Reserve in Kenya. He recently caught sight of an unusual foal. Its deep black coat was covered with white spots. 

"At first I thought it was a zebra that had been captured and painted or marked for purposes of migration," Tira tells George Sayagie of the Daily Nation. It is a Kenyan newspaper. "I was confused when I first saw it."

The baby zebra has been named Tira. He has a genetic condition known as "pseudomelanism." It causes oddities in zebra stripe patterns. Ren Larison is a biologist at the University of California, Los Angeles. She explained the phenomenon to Katie Stacey of National Geographic. Zebras are dark skinned animals. Their stripes arise from specialized skin cells called melanocytes. These transfer melanin into some of their hairs. The hairs that have melanin appear black and those that do not appear white. But on rare occasions, something goes awry. The melanin does not show up as stripes.

"There are a variety of mutations that can disturb the process of melanin synthesis. And in all of those disorders, the melanocytes are believed to be normally distributed. But the melanin they make is abnormal," Greg Barsh tells Stacey. He is a geneticist. He works at the HudsonAlpha Institute for Biotechnology.

Genetic quirks can lead to other atypical coat patterns. Natasha Daly is with National Geographic. She reported on a "blonde" zebra at Tanzania's Serengeti National Park. That was earlier this year. The animal appeared to have partial albinism. This is a condition where reduced melanin causes a zebra's stripes to appear a pale, golden color.

Tira's appearance marks the first time that a spotted zebra has been seen at Masai Mara. That's according to Sayagie. But others like it have been observed in Botswana's Okavango Delta. News of the unusual foal spread on social media. Tourists began flocking to Masai Mara "in droves." They wanted to catch a glimpse of him. 

But the future may not be bright for this little zebra. Scientists have long debated the function of zebra stripes. Theories include camouflage and social-signaling. They also include temperature control. Many now think that the black-and-white pattern actually functions as a fly repellant. Flies carry a number of diseases that are fatal to zebras in Africa. Their thin coats make them especially easy to bite. Zebras' stripes seem to disorient flies. This make it difficult for them to stick their landing. Tira may be more prone to dangerous bites without the standard coat pattern.

But Tira might do just fine if he can withstand the flies. Zebras are accepting of difference. That's according to Stacey. Research suggests that animals with atypical coat patterns fit right into the herd.

    i think its cool that they zebra has spots instead of stripes. i think they should protect it so nothing bad happens to it because its rare.

      I agree because seeing a rare animal is cool. They need to keep it for other people to see. This is so rare that maybe even trying to mate it would be so cool so see how the baby looks. Anyways seeing this zebra would be so amazing.

      I would react the same way seeing a rare animal is so cool. This zebra can be used for science and for people to come and see. I would love to go and see it so i can take a picture and show everyone. Seeing an zebra like this is great and cool.

    I would probably still think he is cute.Why do I think this because it makes him special and extra cute.

    My reaction would be insane because I didnt even think of there being a zebra with spots on a zebra and not black and white stripes. I would react that way because it looks cool and when I would see it I would wanna take it home with me and keep it because it looks so cool

    It would be weird to see a Zebra with polka dots because they usully dont have polka dots.

  • Bunny-

    because the colors of the zebra is different then horses horses could be black or white but not spotted or line so flies would stay away form the zebras.

    I would be amazed of how the zebra has those patterns on its body.I think i would react that way because Zebras usually have black and white trips on them.

    I would be like is that even possible for a zebra to be spotted. I think I would react that way because never in my life have I ever even heard of a spotted Zebra.
