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).
Scientific Name: Phocoena phocoena. Description: The harbor porpoise is shy and less playful than many of its relatives. Smoothly breaking the surface about four times per minute, harbor porpoises often make a loud puffing sound as they breathe. They take in and expel air through two blowholes, located near the top of the head.
