Did you know:
- While many people consider sharks to be the world's deadliest animal, you are more likely to be killed by hornets, wasps, bees, or dogs.
- Be glad you're not a shark, moms! The gestation period for a pregnant female shark can range from five months to two years.
- Though, every once in a while, a female shark can reproduce without any contact with a male. This act is known as parthenogenesis.
- Sharks can generate up to 40,000 pounds per square inch of pressure in a single bite. That's easily enough to chomp off a limb.
- 6 years before Steven Spielberg's Jaws, Burt Reynolds starred in Shark. Real sharks were used in filming, and a stuntman was actually killed.
- Sharks have only two blind spots: one in front of the snout and the other directly behind the head.
- A great white shark rolls its eyes into the back of its head when it attacks to protect its eyes from debris and the thrashing of its prey.
- Sharks can use heartbeats to track their prey. They have electricity-sensing nodules on their noses called ampullae of Lorenzini.
- Martha's Vineyard and Nantucket Island inspired the fictional town of Amity Island in Steven Spielberg's 1975 thriller Jaws.
- Unlike humans, whose upper jaw is a fixed part of the skull, sharks can dislocate and protrude their upper jaw to grab and hang onto prey.
- Great white sharks are picky eaters and can determine after one bite whether or not the meal will satisfy their nutritional needs.
- Whale sharks are much larger than the average shark but are friendly filter feeders who use their rows of teeth to eat plankton, not humans.
- The whale shark’s mouth stretches up to 4.5 feet wide, the largest mouth of all shark species.
