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).
Quills have sharp tips and overlapping scales or barbs that make them difficult to remove once they are stuck in another animalâs skin. Porcupines grow new quills to replace the ones they lose. From the tip of the nose to the end of the tail, a porcupine can be from 33 to 46 inches (80 to 115 cm) long. They can weigh from 12 to 35 lbs (5 to 16 kg). Porcupines make shrill screeches, whines, and low grunts to communicate. Porcupines are nocturnal, which means they are active primarily at night.
