Identifying the Central Idea 1.

Sharks can lose up to 30,000 teeth in their lifetime. Sharks have teeth arranged in rows inside their mouths. These teeth do not have roots like human teeth do, so they fall out easily. When a shark takes a powerful bite into its food, several teeth are lost. When these teeth are lost, new ones push forward from the back rows to replace them. Luckily, sharks continually grow new teeth to replace the thousands they lose.

What is the central idea?

• What shark teeth look like

• Sharks lose many teeth over their lifetime.

• Sharks are carnivorous predators.
