It seems as if its horn was sawn off? They sometimes do that to protect the rhino from poachers, wonder where this rhino came from, and if it was done by the zoo.
@lmsa hi Louise... i was back at the zoo this past weekend and listened to the rhino keeper's talk... it seems the great one-horned rhinos don't always have the big pointy horns and this is just the way this particular rhino's horn has grown...
