Ringed Seal. In far northern Canada, then north some more, you will find Baffin Island.
Well into the Actic Circle, the sun never sets in June. It is pure daylight even at 2am.
If you are the adventurous type, you can camp and wander out on the melting ice of Baffin Bay.
Every day, chunks break off, pack ice blows to shore and the ice changes as the brief "summer" approaches.
Various species of seal haul themselves out onto the ice where polar bears roam.
Ringed Seal were the most common mammal seen on this trip.
