What are the differences between steelhead and salmon?

Steelhead and salmon are both types of fish that belong to the same family, but there are some key differences between them. One major difference is that steelhead are a type of trout that can live in both freshwater and saltwater, while salmon typically only live in freshwater and migrate to the ocean. Additionally, steelhead tend to be more silvery in color and have a more streamlined body shape compared to salmon. Steelhead also tend to be larger in size and have a different life cycle, with some populations of steelhead returning to freshwater multiple times to spawn.
