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 body of the Harbour Porpoise is round and offers them layers of fat that help to keep them insulated even in very cold waters. They have a thin tail that fans out behind them. They have a round snout and a small mouth with between 16 and 28 small but sharp teeth on both the top and bottom of the jaw.
