Humpback whales are large baleen whales belonging to the rorqual family. They are classified into a separate genus called Megaptera or “big-winged”. Humpback whales are the only member of this genus, although recent studies have shown that they are most closely related to the fin whale of all other rorquals. Their most defining characteristics are their enormously long pectoral fins as well as the fact they are stockier in shape than other rorquals and have a relatively large head and broad tail. Humpback whales have charmed whale-watchers throughout the world, as they are extremely curious about seafarers and frequently perform aerial displays such as breaching and slapping the water with their fins and tails.
