How much does a North American porcupine weight?

It is hard to guess what a North American porcupine weights. But we have the answer:

An adult North American porcupine (Erethizon dorsatum) on average weights 7.42 kg (16.36 lbs).

The North American porcupine is from the family Erethizontidae (genus: Erethizon). It is usually born with about 491 grams (1.08 lbs). They can live for up to 18 years. When reaching adult age, they grow up to 83.7 cm (2′ 9″). Usually, North American porcupines have 1 babies per litter.
