This catalog contains photographs of nearly 1900 different humpback whales taken in southeastern Alaska from 1979 to present. Each whale can be identified by the unique black and white pattern on the underside of the flukes.  Within this catalog the whales are grouped by color pattern. Whales with no white on their flukes comprise nearly half of the catalog; therefore this color pattern is subdivided by the width (narrow or wide) of the notch between each fluke.  Each color division contains pages of thumbnail photographs. Located directly under each photo is a unique identification number for each whale.
