Not something you see every day:
"A zebra at Zurich Zoo appeared to be staring into the jaws of death when visitors saw it nose to nose with an open-mouthed hippopotamus.
But the hippo had no intention of having the zebra for lunch – it was having its teeth cleaned.
The extraordinary sight was captured by photographer Jill Sonsteby, from Jacksonville, Florida.
She said the teeth-cleaning session lasted 15 minutes and the zebra came to no harm."
