Harbor porpoises have a small, robust body with a short, blunt beak and a medium-sized triangular dorsal fin.Harbor porpoises mainly eat schooling fish, like herring and mackerel. Occasionally, they will eat squid and octopus.
They are most often seen singly, in pairs, or in groups of up to 10, although there are reports of aggregations of up to 200 harbor porpoises. Most seasonal movements appear to be inshore-offshore and may be influenced by prey availability or the presence of ice-free waters.
