Wild Chronicles heads to the wintry waters of the North Atlantic to solve a mystery—two populations of seals share Sable Island's harsh environment, yet one is thriving and the other is not. To find out why, scientists called on National Geographic's Crittercam® to help them see as seals see and go where humans can't. Now Crittercam® is back from the deep freeze, the evidence is in and the mysteries of the seals are exposed.

  1. What two types of seals inhabit Sable Island, Nova Scotia, Canada?

  2. What is the major difference between the two types of seals?

  3. Scientists on Sable Island use Crittercam® to observe seal behavior. What particular behavior do they hope to observe?

  4. Do both seal populations feed on the same food source?

  5. What is the difference in the hunting techniques of the seal populations?
