The Journey of Humpback Whales

The Journey of Humpback Whales

Humpback whales Humpback whales are mammals, not fish. This means they can't breathe underwater. Humpbacks have two big nostrils (blowholes) on the top of their heads and must come to the surface to breathe.

Adult humpbacks can stay underwater for up to 45 minutes and dive to a depth of 180 metres.

They're called humpbacks because they arch their backs when they dive.

Humpbacks are known as " acrobats of the sea" because they leap out of the water. This is called breaching. Humpbacks breach to impress other whales and remove little creatures like barnacles and sea lice from their bodies.

Fact, each humpback has different white, grey and black patterns under its tail.
