5 ‘toothy’ facts about sharks

Since I’m still waiting for Conne to arrive from her WIG Session meeting, here are five interesting tooth-related facts about sharks.

Do you know that:

1. New teeth are constantly being formed in rows in a shark’s jaw. Shark’s teeth are normally replaced every eight days.

2. Some species of sharks can shed as many as 30,000 teeth in their lifetime.

3. Whale Sharks have approximately 300 rows of teeth, with hundreds of tiny teeth in each row.

4. A significant physical trait that separates a modern shark from an ancient shark is the protrusile jaw, which gives the modern shark more biting force.

5. A shark’s skin is embedded with dermal denticles, which resemble teeth.

If you want to verify if these bits of information are true, please be my guest, ask your friendly neighborhood shark and let me know how it goes. ;-p
