The Intricacies of Humpback Whales' Bubble-Net Feeding

What is the phenomenon observed in the video involving humpback whales?

• Lobtailing

• Breaching

• Tail slapping

• Bubble net feeding

What does the initial whale do to start the bubble net feeding process?

• It spirals upwards while releasing air

• It swims rapidly in a circle

• It dives deep and stays silent

• It jumps out of the water

What is the primary purpose of the bubble net created by the whales?

• To communicate

• To trap and concentrate prey

• To rest

• To play

What role do the other whales play while one whale starts the bubble net?

• They help in creating more bubbles

• They wait passively

• They herd the prey into the bubble net

• They compete for food

How do whales ensure the prey is driven upwards towards the surface?

• By one whale vocalizing to drive the fish up

• By breaching simultaneously

• By creating loud noises

• By swimming away from the prey

Which technique do whales use to corral the prey?

• Singing

• Blowing more bubbles

• Flanking and corralling

• Using their tails

What is the final action of the whales before feeding?

• They disperse into deeper waters

• They breach the surface

• They converge at the center of the bubble net

• They dive deeper

What happens just before the whales feed at the surface?

• The net dissolves

• The whales gather at the center of the net

• The whales separate

• The prey escapes
