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).
Harbor porpoises are found throughout the temperate coastal waters of the Northern Hemisphere.As their name suggests, they prefer the shallows, less than 500 feet (152 meters) deep, and are commonly seen in harbors and bays. They are also known to frequent inland waters, including rivers, estuaries, and tidal channels.ize relative to a 6-ft (2-m) man: Harbor porpoises are shy, elusive sea mammals whose numbers are declining primarily because they are frequently caught by accident in commercial fishing nets.
