6. Interview with Anna Goldman, Mammals Preparator
Q: How do dolphins stay warm?
A: Dolphins have a thick layer of fat underneath their skin called blubber. This helps them stay warm. They also have reduced limb size, which reduces loss of body heat.

7. Interview with Anna Goldman, Mammals Preparator
Q: What’s special about dolphin teeth?
A: Dolphins have sharp interlocking teeth that allow them to eat a variety of fish, squids and crustaceans.

8. Interview with Anna Goldman, Mammals Preparator
Q: What’s one cool fact about orcas?
