Harbor Seal Facts | Harbor Seal Diet & Habitat

Let us know about some of the most fascinating harbor seal facts including harbor seal diet, habitat, reproduction, species and its physical features. The harbor seal (Phoca vitulina) is a true seal that inhabits all throughout the moderate and Arctic marine coastlines of the Northern Hemisphere. These seals are also referred to as the common seal. The most extensively distributed pinnipeds are eared seals, true seals, and walruses and they exist in the Pacific and Atlantic waters, as well as in the North Seas and Baltic waters. These types of seals are brownish-grey in color and they have V-shaped nostrils. They can grow to a size of about 1.85 meters. There were around 25,000 harbor seals in California back in 1984. These seals more preferably reside along the coast shorelines of the state. These animals primarily feed on codfish, sculpin, herring, hake, flounder, anchovy, and littoral. The population of few species has declined rapidly due to disease and possible encounters with humans accidentally. These species are residing in the Baltic Sea, Greenland, and Hokkaido. These animals are given legal protection by the 1970 Conservation of Seals Act.
