Zebra plural

I am not sure of the plural of zebra....here are some at the Western Plains Zoo in Dubbo Australia. If I was a zoo animal I would choose to live here. There are many endangered species here and the aim is to breed them is a situation as close to possible to their native habitat. The area is large and you need to drive around (or pedal if you have a bike). I particularly liked the Galapagos tortoises which have a underfloor heating in their house to keep them warm in winter.

No time for comments as we have a three and five year old with us...
