Comments on Atlantic halibut illustration – 10.20.14

{C}1.     The broadest part of the dorsal fin and the broadest part of the anal fin should be even with each other. This will show the “diamond” shape that usually makes halibut stand out. Take a look at the Pacific halibut image on FishWatch for comparison.

2.     The eyeballs should appear rounder and not looking straight up. See image below provided by staff. Check out the Wikipedia illustration, which shows the eyes looking more to the sides of the fish.


The reviewer indicated that the proportions of the mouth aren’t quite right. Take a look

Atlantic halibut, Hippoglossus hippoglossus

Physical description from Wikipedia:


The Atlantic halibut is a right-eyed flounder. It is flattened sideways and habitually lies on the left side of its body with both eyes migrating to the right side of its head during development. Its upper surface is a uniformly dark chocolate, olive or slate colour, and can be almost black; the underside is pale. The end of the caudal fin is concave.[4] Young fish are paler with more mottled colouration.[5]

This website also has a good description.


This is not only the largest of flatfishes, but is one of the best characterized; its most obvious distinctive characters, apart from its size, being the fact that it lies on the left side;[21] that its mouth gapes back as far as the eyes, and is armed with sharp curved teeth; that the rear edge of its tail fin is concave, not rounded; that its two ventral fins are alike; and that its lateral line is arched abreast of the pectoral fin. Furthermore it is a narrower fish, relatively, than most of our flatfishes (only about one-third as broad as it is long) but is very thick through, and its eyes are farther apart than they are in most of the other flounders.

The dorsal (long) fin (98 to 105 rays) commences abreast of the eye and runs back the whole length of the fish, broadening but slightly for the first third of its length and then abruptly, to narrow again toward the caudal peduncle. The anal fin is similar to the dorsal fin in shape but is shorter (73 to 79 rays), originates close behind the pectorals, and is preceded by a sharp spinelike extension of the post-abdominal bone, which projects in young fish but is hidden by the skin in old fish. The two pectoral fins are of different shapes, the one on the upper (eyed) side of the fish being obliquely pointed while the fin on the lower side is rounded. The rather small ventral fins, which are situated in front of the pectorals and are separated from the anal by a considerable space, are alike. Halibut, like other flatfishes are scaly on the whole head and body and they are very slimy with mucus.


The halibut is chocolate to olive or slaty brown on the eyed (upper) side. Young fish are paler, and are more or less mottled, while large ones are more uniform and darker, sometimes almost black. The blind (lower) side usually is pure white in small fish, but large ones are often more or less blotched or clouded below with gray (known by fishermen as "grays"). Occasionally a halibut is taken the blind side of which is marked with patches of the same color as the eyed side. And we have seen one medium-sized fish in which the rear third of the lower surface was uniform dark brown.
