If you ever want to feel insignificant, just think about the sheer size of a humpback whale. With adults growing up to 56 feet long, humpback whales are one of the biggest mammals on Earth. In February, Hawaii celebrates the return of these migrating giants with its Maui Whale Festival. This month-long event encourages people to get involved in conservation efforts and includes whale-watching tours, allowing closer views of these beautiful creatures.
