The harbour porpoise is among the smallest of cetaceans, with a low, dark, triangular dorsal fin and small rounded head. It is difficult to observe unless conditions are very calm, and is often wary of boats. Porpoises are usually alone or in small groups. They often make a sharp puffing sound when surfacing to breathe (and in some places are known as Puffing Pigs).
They are abundant all around Iceland throughout the year but most commonly seen on whale watching tours in summer months (March/April to September/October).
