Humpback whale

Humpback whale (Megaptera novaeangliae) is îne of the larger baleen whales, adults range in length 12–16 metres. Humpbacks has a distinctive body shape, with unusually long pectoral fins and a knobbly head. It is an acrobatic animal, often breaching and slapping the water with its tail flukes and pectoral fins.
Humpbacks feed only in summer in subpolar and temperate waters, including waters of the Russian Far East. Their diet consists mostly of krill and small fish. In Karaginsky Island area we observed humpbacks feeding on Pacific sand lance (Ammodytes hexapterus). In Commander Islands they most likely feed on Calanus sp. and krill. In winter humpbacks migrate to tropical or sub-tropical waters to breed and give birth. The whales from the Russian Far East mostly migrate to Ogasawara, Okinava and Phillipines. Males at the breeding grounds produce a complex whale song, which lasts for 10 to 20 minutes and is repeated for hours at a time. The purpose of the song is not yet clear, although it appears to have a role in mating. During the winter, humpbacks fast and live off their fat reserves. Humpbacks have a diverse repertoire of feeding methods, including the bubble net feeding technique.
