Halibut are a large flatfish that can reach several hundred pounds. They begin life looking like most 'normal' fish but as they mature both eyes migrate to the same side of their body and they turn onto their sides. As adults their upper side is dark brown and their bottom side is a bright white color. They are a very popular deep see sport fish and are also an important source of income on a commercial basis. They are opportunists and will eat just about anything that they can fit in their mouths.
