Halibut (Hippoglossus hippoglossus Linnaeus) Jordan and Evermann, 1896-1900, p. 2611. Description.—This is not only the largest but one of the best characterized of flatfish, its most obvious diagnostic characters, apart from its size, being the facts that it lies on the left side;44 its mouth is large, gapes back to the eyes, and is armed with sharp curved teeth; its tail is emarginate, not rounded; its two ventral fins are alike; and its lateral line is arched abreast of the pectoral fin. Further- more it is a narrower fish, relatively, than most of our flounders (only about one- third as broad as long) but very thick, and its eyes are more widely separated than in most 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 is similar in outline but shorter (73 to 79 rays), originates close behind the pectoral, and is preceded by a sharp spinelike projection of the post-abdominal bone, which projects in young fish but is hidden by the skin in old fish. The two pectoral fins are unlike, 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 ventrals, which are situated before the pectorals and are separated from the anal by a " Left-handed halibut have occasionally been Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States Fish Commission.
