A 'parr' is a juvenile salmon or trout, specifically in the stage of development when they have characteristic vertical markings called 'parr marks' on their sides. 🏞️ These markings help them camouflage in freshwater streams. They're like the awkward teen phase for salmon, before they head out to the ocean to become adults. Parr typically live in freshwater for one to three years. Think of them as the 'freshmen' of the salmon world. Their survival in this stage is crucial for the future salmon population. 🐟
