Shortfin Mako Shark
Wouldn’t it be nice if our teeth replaced themselves whenever we needed a fresh set? No more drills. No more crowns. No more denture adhesives. That’s what happens to sharks.
In fact, some sharks replace their teeth every few weeks.
The teeth inside a shark’s mouth are arranged in rows, like seats in a theater. While the outermost teeth do the work of grabbing, cutting, or crushing prey—their function varies from species to species—the inner rows of teeth mature. Then, when the shark sheds the worn outer teeth, the next row takes their place.
It’s a process that continues throughout the shark’s life, with teeth being replaced more frequently the more actively the shark feeds.
Ever encounter a shark’s teeth up close? If so, you’re in a very small minority. Despite all the attention they get in the news, shark attacks on humans are actually quite rare. They’re generally no more eager to meet us than we are to meet them
Even so, it never pays to tempt fate! So pay attention to warnings when you’re swimming in areas know to be frequented by sharks.
