Humpback whales are the most acrobatics of whales, heaving their massive bodies by leaps and turns out of the water. Humpbacks are both cosmopolitan - found in all oceans - and endangered. Only about seven percent of their pre-whaling numbers remain. Coastal feeders who love shorelines, bays, and fjords, they are naturals for Alaska, which boasts nearly 34,000 miles of tidal shoreline. Glacier Bay humpbacks have been observed working singly or in pairs to cast a "net" of bubbles about their prey and then harvesting the hapless creatures, probably shrimp and other slower moving organisms, caught in their airy illusion.

The situation of whales, particularly of the endangered humpback whales, in Glacier Bay has recently been under intensive scrutiny by scientists. The purpose of the studies has been to learn enough about these awe-inspiring creatures to protect them. The numbers of whales present can vary dramatically from year to year. Whether these variations are wholly natural or not is uncertain.

Each summer 15 to 20 humpback whales regularly feed in park waters, concentrating in the lower part of the bay. They migrate here from their winter home in the warm waters off Hawaii and can often be seen along the shorelines of Southeast Alaska. Special regulations go into effect when large concentrations of whales are in the park. The regulations affect vessel speed limits and travel routes in certain areas.
