Humpback whales are one of the biggest whales. They can grow 16 meters long and weigh 25 tones.
Humpback whales eat some of the smallest things on earth called krill, but they also eat small fish.
We saw three humpback whales in Madagascar. They were very cool and they swam right under our dinghy. We could see their shapes under the water. It was super scary but it was also very awesome!
Humpback whales move 25000 km every year in big groups. When they reach warmer waters they mate and give birth. When the babies are big enough they all migrate back to the Antarctic where there is more krill for them to eat.
Bubble net fishing...
They dive down and blow lots of bubbles in a circle.
All the bubbles confuse the fish and they feel like they can't swim away.
The whales swim upwards with their mouths fully open and swallow all the fish.
