Lesson Express

Q: How do the fish become vulnerable to seabird attacks?
A: The herring are pushed to the surface by tidal currents, making them prey for the seabirds.

Q: How do the whales use teamwork to hunt?
A: The humpback whales use bubble net feeding, where a dozen whales come together to harvest the herring.

Q: How does bubble net feeding work?
A: The lead whale dives first to find the fish. The rest of the whales follow in formation. Once the lead whale locates the fish, it blows a net of bubbles that encircles the fish. Another whale will call to synchronize the group. The fish are panicked by the whale sounds and blinded by the fizzing bubbles, making it easy for the whales to harvest a large batch of fish.
