It’s a situation you never want to find yourself in. You’re on vacation, peacefully enjoying the planet’s natural wonders and then – out of nowhere – a wild creature attacks.  

While these encounters are usually very rare, Kyle Patterson, spokeswoman at Rocky Mountain National Park, say it's because people aren't aware of their surroundings or don't use common sense. 

"Any wildlife can be unpredictable," she said. "Sometimes you see a visitor who sees an animal and think, 'they’re close to the road, I'll just get out and a take a picture.' This isn’t a zoo where it is fenced off." 

Every animal responds differently to human interaction, but a general rule of thumb for any wildlife encounter is be prepared and look for signs.

"If the animal is reacting to you, you’re too close. All wildlife will give you a sign.  Some species will put their ears back.  Some will scrape their paws.  Some will give verbal cues," said Patterson.

In order to help you, we’ve come up with a list of tips for surviving all kinds of animal encounters, from bison to sharks.

Even with this list handy, remember that it is illegal to approach wildlife at the national parks and no matter how prepared you are, expect the unexpected.
