Humpback whale (Megaptera novaeangliae) sounding, Seymour Canal, Admiralty Island, Southeast Alaska, USA.
Humpback whales probably raise their flukes up high like this when sounding if they are going to do a steep vertical dive down to deeper water, but less so when they are just going to be swimming at shallower depths.
This photo was used by Athena International in the late 1980s for posters and cards.
