Tilefishes, also known as blanquillo, are mostly small perciform marine fish comprising the family Malacanthidae. They are usually found in sandy areas, especially near coral reefs.〔(Discoverlife.org )〕 Commercial fisheries exist for the largest species, making them important food fish. However, the US Food and Drug Administration warns pregnant or breastfeeding women against eating tilefish and some other fish due to mercury contamination. 〔 〕 〔 〕 The smaller, exceptionally colorful species of tilefish are enjoyed in the aquarium. ==Description== The two subfamilies appear to be morphologically different, with members of Branchiosteginae having deep bodies, large heads, and large, somewhat subterminal mouths. In contrast, members of Malacanthinae are slender with elongated bodies, smaller heads, and terminal mouths. Tilefish range in size from 11 cm (yellow tilefish, ''Hoplolatilus luteus'') to 125 cm (great northern tilefish, ''Lopholatilus chamaeleonticeps'') and a weight of 30 kg. Both subfamilies have long dorsal and anal fins, the latter having one or two spines. The gill covers (opercula) have one spine which may be sharp or blunt; some species also have a cutaneous ridge atop the head. The tail fin may range in shape from truncated to forked. Most species are fairly low-key in colour, commonly shades of yellow, brown, and gray. Notable exceptions include three small, vibrant ''Hoplolatilus'' species: the purple sand tilefish (''H. purpureus''), Starck's tilefish (''H. starcki'') and the redback sand tilefish (''H. marcosi''). Tilefish larvae are notable for their generous complement of spines and serrations on the head and scales. This feature also explains the family name Malacanthidae, from the Greek words ''mala'' meaning "many" and ''akantha'' meaning "thorn". 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「tilefish」の詳細全文を読む スポンサード リンク
