The group size is between 2-5 individuals but normally they are more solitary. This species is also very shy and don’t approach the vessels or bow-ride with them. This specie is threatened by human activities like pollution and fishing. We don’t know if this specie is common here in the Azores or if there is a population but a specimen of a female Harbor Porpoise was found stranded on the 4th January 2004, on the rocks of the Terceira Island.
