Halibut Halibut Halibut is a common name principally applied to the two flatfish in the genus "Hippoglossus" from the family of right-eye flounders. Less commonly, and in some regions only, other species of flatfish are also referred to as being halibuts. The word is derived from "haly" (holy) and "butte" (flat fish), for its popularity on Catholic holy days. Halibut are demersal fish and are highly regarded as a food fish. The Pacific halibut is the world's largest flatfish. The IGFA record was apparently broken off the waters of Norway in July 2013 by a 515-pound 8.6 foot fish. This was
Pelagic fish stacks with a range of different spacings. A further complication for fish with bodies that are rounded in cross-section is that the mirrors would be ineffective if laid flat on the skin, as they would fail to reflect horizontally. The overall mirror effect is achieved with many small reflectors, all oriented vertically. Though the number of species is limited, epipelagic fishes are abundant. What they lack in diversity they make up in numbers. Forage fish occur in huge numbers, and large fish that prey on them are often sought after as premier food fish. As a group, epipelagic fishes form
