Total length 130-200 cm; weight 45-75 kg. Harbor Porpoises are small cetaceans, growing to a maximum length of only ¢.200 cm. Most adults are less than 180 cm long. Body is robust, with small appendages. There are small tubercles (or denticles) on the leading edge of the dorsal fin and sometimes also on flippers. Beak is very short and poorly defined, and dorsalfin is low, triangular, and wide-based. Color pattern is somewhat bland at first appearance, but it is actually more complex when analyzed in detail. Body is generally counter-shaded, with a dark gray back and white belly. Generally, dark and pale regions blend into each other, but margins between the two are often splotchy and streaked. Appendages are all dark, and there is a dark stripe running from gape to flipper, and there are also dark streaks on the lower jaw. There is a great deal of individual variation in color pattern, but no obvious differences among different populations ...
