Two 'lovely and charismatic' giraffes were killed by a lightning strike at a Florida wildlife park last month.
Lion Country Safari, west of West Palm Beach, has confirmed that pathology test results and that the deaths were instantaneous.
Officials say Lily and Jioni were in a field on May 3 when a severe thunderstorm quickly developed.
'It's like a billion-to-one chance this happened to us and our poor giraffes, but we are looking at anything we can to improve upon' safeguards for the animals, a spokeswoman told NBC News.
There were a number of shelters in the park for the giraffes if the giraffes chose to use them, the park wrote on Facebook.
Lily was around 4.8m tall, while Jioni was stood at 3.6m.
An Instagram post by the park, said: 'The keepers and our whole team were understandably devastated by this sudden and tragic loss; out of respect for their mourning and the pending pathology results, we waited to share this information. We continue to mourn our two incredibly lovely and charismatic giraffe; they will both be sorely missed.'
The park calls itself a cageless zoo, and has around 1000 animals.
Visitors can walk or drive their cars, with animal feeding and displays also on offer.
Chimp and lions are among the other animals.
