Interesting Alaskan Wildlife Facts

HUMPBACK WHALES
Before the era of commercial whaling, an estimated 15,000 humpback whales roamed the North Pacific. Today, approximately 500 of these majestic creatures summer in Southeast Alaska waters. Reaching lengths of up to 55 feet (16.7m), with the average length being 42 feet (12.7m), an adult humpback is about the size of a typical charter boat! How do you know the whale you've spotted off the bow of the Caledonia is a humpback? One distinguishing features is the whale's uncommonly long flippers. Also, look for a black and white pattern on the ventral side of the animal when it lifts its fluke to dive. All whales make sounds but the humpback is known to have the most diverse "language" employing many sounds including grunts and chortles.

BROWN BEAR The term "brown bear" is often used interchangeably with the word grizzly to refer to members of the species Ursus arctos, a type of bear found throughout coastal and inland Alaska. Brown bears, which range in color from dark brown to blond, have a prominent shoulder hump which easily distinguishes from their cousin the black bear. Protein rich salmon are an important part of their summer diet and they can often be seen feeding in inter tidal zones or by streams where salmon are spawning. The average weight of an adult male is 500-900 pounds. For safe viewing of bears, a respectful distance and a respectful attitude are advisable. Give them at least 100 yards if not more. Be especially cautious when encountering a female with offspring as she is liable to be very protective of her young.
