Some species can lose and regrow up to 30,000 teeth in their lifetime. 4. **Ancient Survivors**: Sharks have existed for over 400 million years, predating the dinosaurs. 5. **Varied Reproduction**: Sharks reproduce in different ways—some lay eggs (oviparous), others give birth to live young (viviparous), and some do both through *ovoviviparity*.
