Animal's “Sixth Sense”

Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island's coast clearly 3 wild beasts,with no dead animals found.

They have a sixth sense. They know when things are happening,”

Animals13 rely on the known senses such as smell or hearing to avoid danger such as predators（食肉动物）.
The notion of an animal “sixth sense”一or14other mythical power一is an enduring one which the evidence on Sri Lanka's ravaged coast is likely to add15.
