Princeton Researchers Assist in Kenya’s Grevy’s Zebra Census
LAIKIPIA, Kenya (CNN) — In the rolling green hills of Kenya’s Rift Valley, the search is on for one of the rarest of all zebras, the elusive Grevy’s zebra.
It’s one of Kenya’s most critically endangered species, and scientists want to know just how many remain.
They’re doing it by looking at their stripes.
Every zebra’s stripes are unique, it turns out: a natural bar code. Now with new technology, scientists can read them like a bar code as well.
