Witnesses told officials that the woman had crossed over the barrier in order to take the photo, and that the animal never left her enclosure but was able to grab the woman when she came close. Unfortunately encounters like this aren't uncommon and can often lead to the animal being killed, like in the shooting death of Harambe the gorilla and Margaash the leopard.
Fortunately, the zoo in this case confirmed that the jaguar was safe and would not be euthanized for wounding the woman.
"We can promise you nothing will happen to our jaguar," the zoo said on Twitter. "She’s a wild animal and there were proper barriers in place to keep our guests safe."
