Whitefish are very scaly fish that can reach a variety of sizes.
They can be medium in size, growing as large as 10 to 12 pounds, or then can be less than a pound in weight in their adult form. They have a small dorsal fin and a very definitive and forked tail. Whitefish can have as many as 70 to 100 scales, and they have small heads. They don't have many teeth. And the teeth they have are small and frail.
