Giant waves crashed onto the shores of Sri Lanka, destroyed entire villages and killed thousands of people. But wildlife officials say they have not found any carcasses. Animals escaped to higher ground.

The Yala National Park is on the southeast coast, and it's home to hundreds of animals, including elephants.

Dr. Patricia O'Hardley worked as an associate professor of veterinary medicine at Michigan State University. She says elephants are able to sense sound waves. And while experts believe animals do have a heightened sense for danger, it is not proven.

Other countries hit by the Tsunami have reported dead domestic animals found.
