The species is native to shallow parts of the western Atlantic from Nova Scotia to Argentina and also the eastern Atlantic, the Mediterranean Sea and off Angola on the west coast of Africa. In its appearance and habits, the grey triggerfish is a typical member of the genus ''Balistes'' except for its drab, uniformly grey colouration. It is a relatively small fish, usually less than 2.3 kg (5 lb) in weight. It is fished recreationally and despite its tough skin, is an excellent food-fish. ==Description== The grey triggerfish is a medium-sized fish that can grow to , but a more common length is . The small beak-like mouth at the tip of the snout has fleshy lips. The eyes are set far back near the top of the head. The body is laterally compressed and deep-bodied with a tough, leathery skin. The front dorsal fin has three spines, the first being very strong and much longer than the other two. The second dorsal fin has 26 to 29 soft rays and is much the same size and shape as the anal fin directly below it which has no spines and 23 to 26 soft rays. The pectoral fins are small and rounded. The outer rays of the caudal fin are elongated in larger individuals. The scales on the head and front half of the body are large while those on the hind half are smaller and smooth.〔 This fish is predominantly pale grey, greenish-grey or yellowish-brown. The body has three indistinct broad dark bars and there is a pale streak on the chin. The upper part of the orbit of the eye is blue and there are some small blue spots and lines on the dorsal fins and upper parts of the body, and sometimes white dots and irregular lines on the lower parts of the body. Both the second dorsal and the anal fin present a somewhat marbled appearance. The body colour fades a little as the animal gets older: juveniles are more colourful.〔〔 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「Grey triggerfish」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
