A humpback whale “lobtailing.” The animal assumes an inverted position and, with the entire posterior part of the body out of the water, begins to wave the gigantic flukes back and forth, lashing the water into foam. ] Many of the gunners believe that lobtailing is indulged in to free the whale’s flukes from the barnacles which fasten in clusters to the tips and along the edges. I do not believe that this supposition can be correct for the barnacles are embedded too firmly in the blubber to be dislodged by such beating. That the animals come into shallow water and rub against rocks to rid themselves of parasites, as whalemen report, seems much more probable. The playful disposition of these whales is manifested in other ways. Very frequently when a ship is hunting a single humpback the animal will play tag with the vessel. It will come up first on one side and then on the other; “double” under water and rise almost at the stern; thrust its head into the air or plunge along the surface with half the body exposed but always just out of range of the harpoon-gun. Sometimes this will last for two or three hours or until the whale is killed; at others the animal will seem to tire of the game and with a farewell flirt of its tail dive and swim away. Captain Scammon says: In the mating season they are noted for their amorous antics. At such times their caresses are of the most amusing and novel character, and these performances have doubtless given rise to the fabulous tales of the swordfish and thrasher attacking whales. When lying by the side of each other, the Megapteras frequently administer alternate blows with their long fins, which love-pats may, on a still day, be heard at a distance of miles. They also rub each other with the same huge and flexible arms, rolling occasionally from side to side, and indulging in other gambols which can easier be imagined than described.[2] Footnote 2: “The Marine Mammals of the North-western Coast of North America.” By Charles M.
