Sero types H7N7, H4N5, H4N6, H3N8, and H3N3 have been found in harbor seals (Phoca vitulina
) on the New England coast of the United States.
In fact, these sharks show preference for northern elephant seals (Mirounga angustirostris) and harbor seals (Phoca vitulina
) over sea lions (family Otariidae) and sea otters (Enhydra lutris), for pinniped pups over adults, and for baleen whale blubber over muscle.
Tambien han servido para detectar cuellos de botella en el caso de dos poblaciones de Phoca vitulina
en Holanda y Escocia (Kappe et al.
Persistent organic pollutants are environmental contaminants that, because of their lipophilic properties and long half-lives, bioaccumulate within aquatic food webs and often reach high concentrations in marine mammals, such as harbor seals (Phoca vitulina
Researchers at England's Royal Society for the Prevention of Cruelty to Animals (RSPCA) raised six orphaned harbor seal pups, Phoca vitulina

Some important mammals observed in the Sedge Islands region are the red fox (Vulpes vulpes), muskrat (Ondatra zibethicus), racoon (Procyon lotor), river otter (Lutra canadensis), and harbor seal (Phoca vitulina
Harbor seals (Phoca vitulina
), gray seals (Halichoerus grypus), harp seals (Phoca groenlandica), and hooded seals (Cystophora cristata) are all "true seals" of the family Phocidae, and should not be confused with the sea lions commonly seen at zoos or in aquarium shows.
Such injured biological resources included bald eagles (Haliaeetus leucocephalus), black oystercatchers (Haematopus bachmani), common loons (Gavia immer), clams, common murres (Uria aalge), cormorants (Phalacrocorax, three species), cutthroat trout (Oncorhynchus clarkii), Dolly Varden trout (Salvelinus malma), harlequin ducks (Histrionicus histrionicus), harbor seals (Phoca vitulina

For example, National Marine Fisheries Service scientists are presently using both nuclear and mitochondrial DNA to examine population structure in white whales (Delphinapterus leucas), harbor seals (Phoca vitulina
), spinner dolphins, and other species.
Indeed, such concerns prompted Osterhaus and his colleagues at the National Institute of Public Health and Environmental Protection in Bilthoven, the Netherlands, to launch a unique study involving harbor seals (Phoca vitulina
