Dolphins Facts

• There are dolphins with 8 teeth and there are some with 250. Bottlenose dolphins have 88-100 teeth. They only get one set of teeth for life. Dolphins do not use their teeth to chew their food, but they use their teeth to catch their food and then they swallow it whole. 
• A curved dorsal fin in the middle of their back, along with powerful, broad flukes on their tail and a pointed flipper on each side allow bottlenose dolphins to swim speeds up to 35 km/h (22 mph) and dive as deep as 915 m (3000 ft.). They have a thick layer of blubber which helps them maintain their body heat and protects them from predators such as killer whales and large sharks. They have sensitive, smooth skin that flakes off and gets replaced every few hours.
