Arctic char is a remarkable and versatile fish species that inhabits cold, freshwater environments in the Northern Hemisphere. These fish display various colors depending on their age and environment. Typically, char have a dark greenish to brownish back, silvery sides, and a white or pale-colored belly. Some fish develop vibrant red, orange, or pink colors, especially during the spawning season. They can be anadromous, migrating between freshwater and saltwater, or they may spend their entire lives in freshwater.
