There are six types of Salmon in North America. Five come from the Pacific coast and are called Pacific Salmon. These are Chinook, Coho, Sockeye, Pink, and Chum Salmon. The other one traditionally lives in the Atlantic and is simply called Atlantic Salmon. All Salmon have a few things in common. They’re strong predators that like cold water. They normally live in the sea, but they move into freshwater to spawn. When they do, they transform, changing color, even shape, to give them an upper hand.
