Habitat
Harbor porpoises primarily inhabit coastal waters, including bays, estuaries, and shallow seas in temperate and subarctic regions. They are found in the North Atlantic and North Pacific Oceans, preferring depths of less than 200 meters and avoiding open ocean areas.
Diet
Harbor porpoises mainly feed on small fish such as herring, mackerel, and sand lance. They also eat squid and occasionally shrimp, using echolocation to hunt in murky waters, with feeding activity peaking during the day in shallow coastal areas.
Behavior
Harbor porpoises are typically solitary or form small groups of up to five individuals, and they are active during the day with quick, rolling surface movements. They exhibit shy behavior, avoiding boats and loud noises, and are not known for acrobatic displays like some other dolphins. Their social structure is loose, with individuals often traveling alone or in pairs.
Conservation Status
The IUCN classifies the harbor porpoise as Least Concern globally, but some subpopulations, like those in the Baltic Sea, are endangered due to threats such as bycatch in fishing nets and habitat pollution.
