Tenth Grade Talking Points

• Orcas, also known as killer whales, are the largest members of the dolphin family. They are highly intelligent and social animals, living in groups called pods. They are known for their distinctive black and white coloring and their powerful hunting abilities.
• One interesting fact about orcas is that they have complex communication and vocalization patterns. They use echolocation to locate prey and navigate through the ocean. This makes them one of the most sophisticated predators in the marine world.
• Orcas play a crucial role in the marine ecosystem as top predators. They help maintain the balance of the marine food web by controlling the population of their prey, such as seals, sea lions, and fish. Their presence is essential for the health of the ocean ecosystem.
