It is hard to guess what a Harbour porpoise weights. But we have the answer:
An adult Harbour porpoise (Phocoena phocoena) on average weights 52.72 kg (116.23 lbs).
The Harbour porpoise is from the family Phocoenidae (genus: Phocoena). It is usually born with about 8.89 kg (19.6 lbs). They can live for up to 15 years. When reaching adult age, they grow up to 1.53 meter (5′ 1″).
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The harbour porpoise (Phocoena phocoena) is one of six species of porpoise. It is one of the smallest marine mammals. As its name implies, it stays close to coastal areas or river estuaries, and as such, is the most familiar porpoise to whale watchers. This porpoise often ventures up rivers, and has been seen hundreds of miles from the sea. The harbour porpoise may be polytypic, with geographically distinct populations representing distinct races: P. p. phocoena in the North Atlantic and West Africa, P. p. relicta in the Black Sea and Sea of Azov, an unnamed population in the northwestern Pacific and P. p. vomerina in the northeastern Pacific.
