Chum Salmon are shiny fish that live in the ocean and swim upstream to lay their eggs. They are known for their pinkish color and are a favorite food for many animals!
生息地: Coastal areas and rivers
The Chum Salmon has a silvery-blue back and flanks when in the ocean, fading to white underneath. During spawning, they develop distinctive dark vertical bars or blotches on their sides, and males grow large, hooked jaws with prominent teeth, earning them the nickname 'dog salmon'.
