Summer in the Antarctic
In Summer in the Antarctic, narrator Sir David Attenborough explores the Antarctic Peninsula during summer. As the seasonal thaw unlocks the sheltered bays, a feeding frenzy begins. Humpback whales travel over 5,000 miles to feast on krill, tiny shrimp-like creatures that swarm in the nutrient-rich waters. The whales use a sophisticated hunting strategy called bubble-net feeding to trap and devour massive quantities of krill before winter forces them to migrate north. This video is excerpted from BBC’s Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
Lesson Express
Q: Why do humpback whales migrate such long distances to reach Antarctica?
A: They travel over 5,000 miles to reach the krill-rich waters and feed before winter returns.
Q: What is bubble-net feeding, and how does it help whales catch their prey?
A: It is a cooperative hunting technique where whales trap krill using spiraling bubbles, making it easier to catch them.
Q: What happens to the whales when summer fades in Antarctica?
A: They migrate north to warmer waters to escape the harsh Antarctic winter.
