3. A shark can hear a fish in the water from more than a mile away.

4. Scientists can determine the age of a shark by counting the rings that form on its vertebra, similar to counting the rings on a tree to tell its age.

5. Sharks are cartilaginous fish, which means that the structure of the animal’s body is formed of cartilage, instead of bone.

7.  It is estimated that the whale shark (the largest shark species) can live up to 100-150 years.

9. Until the 16th century sharks were known as “sea dogs”.

10. Some sharks have eyes similar to a cat’s, with a mirror-like layer that allows them to see better in murky water.

12. For every human killed by a shark, 2 million sharks are killed by humans.

13. Most sharks must swim constantly to force water through their mouths and over their gills because they lack the ability to pump water over their gills like the majority of fish.

14. Sharks’ ears are located inside their heads.

15. The tiger shark is the second-most dangerous shark in the world and is sometimes referred to as the “garbage can of the sea” because it will eat anything.
