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 quills are surrounded by long guard hairs which can be dark brown to pale yellow or grey. Porcupines have wooly underfur, and do not have quills on their undersides. Porcupines grow to a size of 23 to 51 inches. Their tails can be from 7 to 10 inches in length. Adult porcupines weigh from 8 to 40 pounds.
