Great White Shark Information

TEETH TO SPARE

If great white sharks had tooth fairies, theyd be rich! A great white loses and replaces thousands of its teeth during its lifetime. Its upper jaw is lined with 26 front-row teeth; its lower jaw has 24. Behind these razor-sharp points are many rows of replacement teeth. The spares move to the front whenever the shark loses a tooth. At any one time about one-third of a sharks teeth are in the replacement stage.

HEADS UP

Great whites are the only sharks that can hold their heads up out of the water. This ability allows them to look for potential prey at the surface. Great white sharks usually attack from underneath, surprising their unwary prey

Slide 3

Great white sharks are superstars. Before the Star Wars series, the 1975 movie Jaws was Hollywoods biggest moneymaker. Jaws, about a great white on the prowl, cost $8 million to film but made $260 million in the U.S. Not bad for a fish story!

Great white sharks can sprint through the water at speeds of 43 miles an hour (69 kilometers an hour). Thats about 8.5 times as fast as the top Olympic swimmer. Scientists on the California coast tracked one shark as it swam all the way to Hawaii2,400 miles (3,862 kilometers)in only 40 days!

Unlike most fish, great white sharks bodies are warmer than their surroundings. The sharks bodies can be as much as 27.3F (15.17C) warmer than the water the fish swim in. A higher temperature helps the great white shark swim faster and digest its food more efficiently. Very useful for an animal thats always on the go!

Speedy Swimmers & Hot On The Trail

Slide 5

A pregnant female great white shark can carry as many as 14 babies in her belly. At birth, a 5-foot-long (1.52-meter), 60-pound (22-kilogram) pup looks and acts like a miniature adult. Great whites average between 10 and 15 feet (3 and 4.6 meters) long. Females tend to be bigger than males. The longest confirmed great white shark measured 19.5 feet (5.9 meters). Male or female, theyre the worlds largest meat-eating fish.

A great white shark isnt all white. A pale belly and dark charcoal-gray back help the shark avoid detection by prey. Viewed from above, the sharks dark-colored back blends with the murky seafloor. From below, the sharks belly matches the light-colored surface. Sneaky!
