King Salmon in Alaska

In the sea, kings have steel-blue backs and heads, silver or white sides and bottom. Large black spots adorn their dorsal fins, backs, sides and lower tail lobes. No other salmon has the distinctive black gum line on the lower jaw. Kings remain at sea two to seven years. They stop eating when they enter fresh water. Like chameleons, they turn a bright red-purple and males develop a hooked snout.
