Great White Shark | Carcharodon carcharias

“The Smithsonian’s National Museum of Natural History has one of the largest collections of fossil shark teeth in the world – more than 90,000 different teeth. The oldest date back about 360 million years to the Devonian Period. Shark teeth come in a wide variety of shapes and sizes, all depending on their purpose. Flat teeth are adapted for crushing and grinding. Sharp and pointy teeth make it easier to grasp and hold slippery prey. Serrated teeth are ideal for ripping and tearing prey too large to swallow in one bite.” -
