Humpback whales have extraordinarily long pectoral fins, nearly one third 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”. On foggy mornings they have been reported as killer whale dorsal fin as will be shown in the next posting….
By late May grizzly bears and cubs are starting to appear on the beaches to turnover rocks. The inter-tidal zone “food” is high in protein and contains crab, clams, barnacles, amphipods and other tiny invertebrates. The “beach food” is important because plant food is relatively scarce during spring as berries do not become part of the diet until July and bears will continue to loose weight until well into June. The cubs rely on mother’s milk that is better than 30% fat. Mother bears tend to be affectionate, protective, devoted, strict, sensitive and attentive toward their cubs, raising them to an age where they can survive on their own. In return the cubs at this age do not stray far from their mother’s side.
