Humped Back Whale.
They are mostly native to Hawaii and Alaska has migrated though these waters, but this migration pattern is not necessarily traditional. They have a general route of migration between Hawaii and Glacier Bay in Alaska.
Another whale seen along the Lost Coast is the: Blue Whale (Balaenoptera musculus)
The blue whale is one of the largest animals ever to have lived on earth. It is almost as long as a Boeing 737 and is the largest of all cetaceans. Typical full-grown length about 82-85 feet Color: bluish-gray with grayish white patches. It has a small triangular dorsal fin (apx 12 in.), located toward the end of its back. Ranges from tropical to subarctic seas around the world.
Feeding, Migration and Population
Blue whales feed almost exclusively on krill and pelagic red crabs. Whenever they spend an extended period of time in a given area, it is usually due to an ample supply of these organisms. Blue whales usually occur alone or in pairs. Large groups have been reported where prey are abundant, particularly off of Mexico.
Studies suggest that Blue whales probably migrate in a pattern that is similar to that of the California Grey whale. They can be seen off the west coast of Baja California in large numbers in April. They appear in the area again in October, but have not been reported between November and January. Catches of blue whales from British Columbia shore stations peaked in June and September, suggesting a northward movement past Vancouver Island in spring and a southward shift in autumn.
Not much is known of the total population of these giants. Because there has been a progressively more frequent number of sightings of the blue whales each year off California. The best guess using current data as been around 2,134 near California in the mid 90's.
