The humpback whale is one of the three mammals that are endangered in Hawaii. The humpback is a medium sized rorqual, but its length is enormous. For instance, a humpback's fluke measures up to 16 feet across, and although it is an ocean animal, the bones in its flippers are shaped to look like hands.
Wartlike knobs cover the head and flippers.
Unlike its name, humpback, they have no hump on their back. There aren't many reasons why the humpback is endangered, and how it got endangered. There are plainly two main reasons why they endangered. Number one, in the 1700-1800's humans killed them for their oil and meat. And number two, it took an impact when whalers killed over 100,000 humpbacks between 1904-1939.
