This question was submitted by Julian in Mrs. James's class.
How long do you think sharks live? Ten years. Fifty years? More than fifty years?
Let's take our toothy friend, the great white shark. How long does he live? Well...
Many of our students want to know how many teeth a shark has. Hmmm. That's a toughie. How about the great white shark? Okay, we've got a more specific answer for you. From the Fox Shark Research Foundation we learn that the "great white's most famous feature is their sharp, serrated, triangular teeth which are arranged in 5 rows and are continuously shed and replaced in a conveyor belt fashion. An adult white shark can have up to 300 teeth in its mouth at any one time."
