The Atlantic halibut (Hippoglossus hippoglossus) is a flatfish of the family Pleuronectidae. They are demersal fish living on or near sand, gravel or clay bottoms at depths of between 50 and 2,000 m (200 and 6,600 ft). The halibut is among the largest teleost (bony) fish in the world, and is a threatened species owing to a slow rate of growth ...
Halibut taken by anglers are generally 15 to 20 lb (6.8 to 9.1 kg) in weight, but fish over 150 lb (68 kg) are regularly caught. The current Alaska state record for a sport-caught halibut is 459 lb (208 kg), [6] and a fish must weigh at least 250 lb (113 kg) to qualify for the state's trophy fish program. Anglers use stout saltwater gear to ...
California halibut typically weighs 6 to 30 pounds (3 to 23 kg), with the largest reported weighing 72 pounds (32.7 kg). It is rare, but they can grow up to 60 inches (1.52 m) [2], and their average length is 12 to 24 inches (30 to 61 cm). [7] The largest fish of this species are females since they grow faster, and males do not grow as large.
Halibut. Atlantic halibut. Halibut is the common name for three species of flatfish in the family of right-eye flounders. In some regions, and less commonly, other species of large flatfish are also referred to as halibut.

The Greenland halibut is a cold-water species found at depths from near the surface to 2,200 m (7,200 ft), but mainly between 500 and 1,000 m (1,600 and 3,300 ft). [2] It is mainly found in waters with temperatures from 1 to 4 °C (34–39 °F), but has also been observed at subzero temperatures down to −2.1 °C (28.2 °F).
Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
Soleidae (true soles) Cynoglossidae (tonguefishes) A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development.
The tides received relatively little attention in the civilizations around the Mediterranean Sea, as the tides there are relatively small, and the areas that experience tides do so unreliably. [ 3 ] [ 4 ] [ 5 ] A number of theories were advanced, however, from comparing the movements to breathing or blood flow to theories involving whirlpools ...
