What Do Whales Do When They Surround Fish Into a Bubble Net?
Humpback whales are known for their unique feeding technique called bubble net feeding. They work together to create a bubble net to trap their prey. Here's how it works:
- Bubble Net: The whales swim in a circular formation, blowing bubbles underwater to create a net.
- Trapped Fish: As the bubble net takes shape, it surrounds the fish, trapping them inside.
- Feeding Spree: Once the bubble net is complete, the whales open their mouths wide and swim through the circle, feeding on the trapped fish.
Benefits of Bubble Net Feeding:
- Increased Efficiency: The bubble net technique allows whales to catch large schools of fish more efficiently than individual hunting.
- Teamwork: Bubble net feeding requires cooperation among whales, strengthening their social bonds.
- Energy Conservation: By surrounding the fish in a bubble net, the whales reduce the amount of energy they need to expend on chasing and catching prey.
