Humpback Whales

Humpback whales have unique songs and use a sophisticated hunting technique called bubble net fishing. This method involves a group of whales working together to trap fish using bubbles as a visual barrier. The lead whale locates the fish, and others follow in formation, creating a net of bubbles. Once the fish are trapped, the whales swim upwards to consume them. This technique showcases the whales' intelligence and coordination, making it one of the most effective fishing methods in the animal kingdom.
