Hillier Lake, Western Australia: The pink and lovely Hiller Lake is the only vividly pink lake you will find in the world. The color is permanent and never changes, even when water is removed and placed in a separate container. Its startling color remains a mystery and while scientists have proven it's not due to the presence of algae, unlike the other salt lakes down under, they still can't explain why it's pink.
Italian diver Cristina Zenato holds a 10-foot shark in her hands in the tropical waters of the Caribbean. She is able to handle the sharks by rubbing hundreds of jelly-filled pores around the animal’s nose and mouth, an action that brings on a natural paralysis that can last for up to 15 minutes. In that amount of time, Zenato, who has been doing this work for 15 years, is able to tend to injured sharks, remove parasites and teach other divers.
