Shark Teeth

Regular price $7.00 $0.00

Shark teeth are not actually teeth. They are made of a hard, durable material called dentin, which is similar to bone, and covered in enamel.

Sharks continually shed their teeth throughout their lifetime and can grow up to 50,000 teeth in their lifetime. Unlike human teeth, shark teeth are layered, meaning that the newer teeth grow in behind the old.

They can have up to as many as 15 rows of teeth or as few as two to three. Interestingly, the size of the teeth can be determined by the sex of the shark. Female sharks tend to have larger teeth due to the increase in overall body size.

Shark teeth have been around for millions of years and have been found in fossils dating back to the Paleozoic era.
