Owen’s 5 key points

1. I learned that most sharks have somewhere in between 4 to 20 rows of teeth. 2. Sharks are always losing teeth . when a tooth from a row falls out the tooth from the row behind moves up and takes it’s place. PLO B2 links because sharks are adapting to losing their teeth. 3. Sharks lose about 20,000 teeth ina lifetime. 4. keep your eyes open on the beach you might see a shark tooth. PLO B3 links because sharks tend to live closer to the shore. 5. The first row of teeth is used for cutting food. PLO B1 links to number 1 because we could use a microscope to analyze their gums
