Or tail of a whale? It is not easy to spot - let alone photograph - humpback whales from the shore! Finding a grey mammal in a vast grey ocean, often at quite a far distance, takes patience. I was lucky enough to spot a couple of them breaching off the coast from an overlook just north of Hanauma Bay after watching for about 7-8 minutes. This was the only photo I managed to get. North Pacific Humpback Whales leave Alaskan waters each fall - a majority of them make the 3500 mile swim to the warm, shallow waters that surround the Hawaiian islands. Sightings are common between December and April. I'll be trying again soon!
