Humpback Whale
The singing traveler of the open ocean/Marine Life
Humpback whales (Megaptera novaeangliae) are famous for their complex songs, which can last over 20 minutes and be heard hundreds of kilometers away. They undertake one of the longest migrations of any mammal, traveling up to 8,000 km each way between feeding and breeding grounds. Their pectoral fins are the longest of any whale species, and they use bubble-net feeding, a cooperatively genius hunting technique.
