Description & Fascinating Facts. The Harbor porpoise, Phocoena phocoena, (a.k.a. Common porpoise), is a small cetacean with a rotund, stocky body that tapers toward the tailstock. This porpoise reaches a maximum length of 1.9m (6ft) and maximum weight of 90kg (198lbs). On average, Harbor porpoises are smaller, and do not exceed 1.5m (5ft) or weigh more than 60kg (132lbs).
The animal has a very thick body and a small head. The colouration is rather like that of a killer whale; the main body of the porpoise is very dark grey to black, with very demarcated white patches on the flank and belly. The dorsal fin is set just back from the middle of the back and sits up erect.
