June 30, 2009 Three seals now call Boston Harbor home Play video

(NECN: Boston, Mass.) - Some new residents are making themselves at home in Boston Harbor.

Cordova, Ursula and J.D. are female Northern fur seals.

Cordova is known for her loud voice.

The three seals are part of the "New Balance Marine Mammal Center" that opens tomorrow at the New England Aquarium.

Trainers at the aquarium gave NECN a sneak preview this morning.

The three females were moved to Boston from an aquarium in New York.

Two large male seals will eventually join them.
