    Wild animals seem to have escaped the Indian Ocean tsunami (海啸), adding weight to

ideas they possess a "sixth sense" for disasters, experts said on Thursday.

    Sri Lanka wildlife officials have said the giant waves that killed over 24,000 people

along the Indian Ocean island's coast seemingly missed wild beasts, with no dead animals

found.

    "No elephants are dead, not even a dead hare or rabbit. I think animals can sense

disaster. They have a sixth sense. They know when things are happening," H.D. Ratnayake,

deputy director of Sri Lanka's Wildlife Department, said on Wednesday.

    The waves washed floodwaters up to 3 km (2 miles) inland at Yala National Park in the

southeast, Sri Lanka's biggest wildlife reserve and home to hundreds of wild elephants.

"There has been a lot of evidence about dogs barking or birds migrating before volcanic

eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal

behaviour specialist at Johannesburg Zoo.

    "There have been no specific studies because you can't really test it in a lab or

field setting," he said.

    Other authorities agreed with this conclusion.

    "Wildlife seem to be able to pick up certain phenomenon, especially birds. There are

many reports of birds detecting coming disasters," said Clive Walker, who has written

several books on African wildlife.

    Animals certainly rely on the known senses such as smell or hearing to avoid danger

such as predators (食肉动物).

    The idea of an animal "sixth sense" is a lasting one that the evidence on Sri Lanka's

damaged coast is likely to add to.
