What are the differences between steelhead trout and salmon?

Steelhead trout and salmon are both types of fish that belong to the same family, but there are some key differences between them. Steelhead trout are a type of rainbow trout that migrate to the ocean and return to freshwater to spawn, while salmon are a separate species that also migrate to the ocean but die after spawning. Additionally, steelhead trout tend to have a more silvery coloration and a more streamlined body shape compared to salmon.
