Whales of the Silver Bank - Pectoral Fin

spinning head breachHumpback whales have extraordinarily long pectoral fins, nearly ? the length of the whale. The length and shape of the pectoral fins facilitate the graceful movement humpbacks are known for, even allowing the whale to swim backwards and turn on a dime. These long pectoral fins are where humpbacks get their scientific name Megaptera novaeangliae or “big-winged New Englander”.
