dge, are clearly visible. These ridges permit this animal to be positively identified as a Bryde's whale. (_Photo by F. Morejohn._)] [Illustration: Figure 31.--Bryde's whales in the Gulf of California and north of Hawaii (inset). In both, note the tall, sickle-shaped appearance of the dorsal fin, much like that of the sei whale. In the animal in the larger photo note the ragged rear margin of the dorsal fin, a frequently observed characteristic in Bryde's whales. In the animal on the left note also the region of gray on the sides in front of the dorsal fin. (_Photos by W. C. Cummings and S. Ohsumi_ (_inset_).)] [Illustration: Figure 32.--Stranded Bryde's whales at Walnut Point, Va. (top) and Panacea, Fla., Gulf of Mexico (bottom). In both animals note the head shape similar to that of the sei whale, and the three distinct head ridges. In the animal on the bottom, note that the two outermost ridges have their origin in grooves beside the blowholes. In the animal on the top, note also the baleen plates, up to at least 300 per side and dark gray with coarse gray bristles. There is infrequently a rather wide interval at the front of the mouth between the left and right rows of baleen. (_Photos by U.S. National Museum, courtesy of J. G. Mead (top) and M. B. Rank, courtesy of Wide World Photos (bottom)._)] HUMPBACK WHALE (B) _Megaptera novaeangliae_ (Borowski 1781) Other Common Names Humpbacked whale, bunch, hump whale, or hunchbacked whale. Description Humpback whales reach a length of 53 feet (16.2 m). The body is robust, narrowing rapidly on the tail stock. The head is quite broad and rounded, somewhat like that of the blue whale. The head ridge characteristic of other balaenopterid species is indistinct and is replaced in prominence by a string of fleshy "knobs" or protuberances, many more of which are randomly distributed on the top of the head and on the lower jaw. There is a distinctive rounded projection near the tip of the lower jaw. Humpback whales carry many barnacles and whale lice. The baleen plates are all black with black or olive-black bristles. The flippers are very long (nearly a third as long as the body), are scalloped on at least the leading edge, and are nearly all white. The dorsal fin, located slightly more than two-thirds of the way back on the back in approximately the same position as that of the fin whale, is small and varies in size and shape from a small, triangul
