Each seal is tagged in both hind flippers after they are weaned at the age of 2months or so.
The letter indicates the year of birth and the number is their id.
Here you see a yearling...a favorite pose by these critters...snoozing on the beach.
This is Kaiwi, an Oahu seal that was born this summer. At birth she weighed about 30 pounds and now weighs around 150lbs...the thing on her back is a cell phone transmitter allowing scientists to be able to track her position and diving depths.
Hard to believe there's only 1100 of them left :(

This is what we called a "cruiser" just checking out the beach areas for other seals
