Sockeye salmon

The red salmon, also known as sockeye, is a Pacific fish that turns bright red when it's time to spawn. These strong swimmers split their lives between the open ocean and freshwater rivers, sometimes traveling over 1,000 miles upstream. Unlike most fish, they only breed once before dying.

• Changes from silver to deep red during spawning season
• Young fish stay in rivers for years before ocean migration
• Eats mostly tiny floating animals called zooplankton
