Harbor seal

Say hello to our harbor seals!

Come see Barney, Hogan and Casey in their beautiful habitat, featuring a spacious pool and plenty of dry resting area (or haul-out space) for them to enjoy. With acrylic viewing panels on three sides and seating for up to 100 visitors (or three entire classrooms of students!) you’re sure to get a prime view of these popular, playful marine mammals.

Quick facts

Harbor seals rely on their thick layer of blubber to stay warm.

Their diet consists of sole, flounder, sculpin, cod, herring, octopus and squid.

Harbor seals can sleep underwater and will come up to breathe every 5 to 10 minutes without waking up!
