comments,
- From up here, they don\t look like much.""Up close, each one is more than 2,000 pounds of smiling marine mammal
- This pod gathers off the shore of an island that\s only inhabited part of the year.""That season, appropriately enough, is perfect for whale watching
- These whales congregate near shore to molt, sloughing off their outer layer of skin against coarse gravel.""But with shallow waters comes real risk for the youngest members of the pod
