The shoal bass (''Micropterus cataractae'') is a species of freshwater fish in the sunfish family (Centrarchidae) of order Perciformes. One of the black basses, it is native to subtropical waters in Florida and Georgia. It is also occasionally found in rivers and streams of East Alabama where it has been declared an endangered species and cannot legally be kept if caught by fishermen. Of typical size for a black bass, ''M. cataractae'' reaches a maximum recorded length of and a maximum published weight of 8 pounds, 12 ounces. Only described for the first time in 1999, ichthyologists are still expanding what is known about the species. The shoal bass is often confused with the redeye bass, due to its red-tinted eyes. It is also often confused with the smallmouth bass, due to its faint vertical stripes along the side of its body. ==Description== This species was formerly considered either a redeye bass or subspecies of the redeye bass. In 1999 it was described as a new species.〔 The red color of eyes associates this species with the redeye and Suwannee bass at first glance. However, it is more closely related morphologically to the spotted bass. Shoal bass are generally olive green to nearly black along the back. A dusky dark blotch about 50 to 67 percent of the size of the eye occurs on the back edge of the gill cover. Three diagonal black lines radiate along the side of the head looking like war paint. Ten to fifteen vertical blotches appear along the sides with tiger-stripes often appearing in between. The belly is creamy or white and wavy lines may appear slightly above the white belly on the sides. The dorsal, caudal and anal fins are dark olive green to grayish black. Pelvic fins may have a cream colored leading edge with dark spots. The shoal bass has scales on the base portion of the soft-rayed dorsal fins, clearly connected first and second dorsal fins, and an upper jaw bone that does not extend beyond the eyes. There are no known subspecies of the shoal bass. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shoal bass」の詳細全文を読む スポンサード リンク
