From the Alaska Department of Fish and Game: At birth, pups have dense, coarse, nearly black fur with a frosty appearance because the tips of the hair are colorless. Color lightens after their first molt in late summer. Most adult females are buff colored on the back. Nearly all males stay darker on the front of the neck and chest; some are even a reddish color. Adult males have prominent, broad foreheads and muscular necks.

I was able to take a 6 hour boat tour of the Kenai Fjords and had the chance to see these Stellar Sea Lions in the wild.
