The Harbour porpoise is one of seven species of porpoise. As its name implies, it stays close to coastal areas or river estuaries. This porpoise often ventures up rivers and has been seen hundreds of miles from the sea. It is one of the smallest marine mammals. Adults grow to 1.4 to 1.9 m (4.6 to 6.2 ft)

Did you know?

The name “porpoise” comes from the Latin for pig (porch). Harbour porpoises are therefore sometimes called “puffing pigs”, due to the sound they make as they breathe. Interestingly, when surfacing for air, these porpoises do not splash; instead they roll from their beak to their fluke and arch their back.
