This species is distinguished by the following characters: body moderately deep and compressed, its depth 2.1-2.5 times in standard length or SL (smaller individuals are deeper-bodied); snout relatively short, 6-6.9 times in SL; eye 3.2-4.5 times in head length (at 12-28 cm SL); mouth small; teeth spatulate, close-set, with denticulate edges, and small for the genus; total gill rakers on first gill arch 13-15; continuous, unnotched dorsal fin IX,24-26; A III,23-24; caudal fin emarginate to lunate, concavity 6.5-9 times in SL (concavity is greater in larger individuals); caudal peduncle narrow, the least depth 10-12 times in SL with a lancet-like spine on each side which folds into a deep horizontal groove; stomach large, U-shaped, thin-walled with large, thorn-like papillae on inner surface; colour brown with longitudinal blue lines on head and body; a yellow area behind eye and 2 yellow bands extending anteriorly from eye; when alive, this fish is capable of changing its ground colour from dark brown to pale blue (Ref. 9808).

Trophic Strategy
provided by Fishbase
Inhabits steep slopes, often in turbid waters, generally in the vicinity of coral reefs or rocky bottoms. May form aggregations. Feeds on zooplankton (Ref. 1921).
Biology
provided by Fishbase
Adults inhabit steep slopes, often in turbid waters, generally in the vicinity of coral reefs (Ref. 58652) or rocky bottoms. They form resident spawning aggregations (Ref. 27825, 48637). Adults often seen in schools, feeding mid-water on plankton (Ref. 48637). Feed on zooplankton. Marketed fresh. Flesh is almost never poisonous (Ref. 4795), but incidence of ciguatera poisoning was reported from Nauru I. (Ref. 125620). The retractile sharp blades of the caudal peduncle can be dangerous (https://www.monaconatureencyclopedia.com/acanthurus-mata-2/?lang=en, ver. 12/2021)

分布
provided by The Fish Database of Taiwan
廣泛分布於印度-太平洋區，西起紅海、非洲東部，東至馬貴斯及土木土群島，北至日本，南至澳洲大堡礁及新加勒多尼亞。台灣各地海域及離島均曾發現，以北部、東北部海域最多。
利用
provided by The Fish Database of Taiwan
一般以流刺網、延繩釣或潛水鏢魚法等捕獲。觀賞及食用兼具。剝皮後，煮薑絲湯，肉質鮮美。尾柄上骨質盾板非常銳利，易傷人，處理時需小心。因食物鰱之關係，可能具熱帶海魚毒。
描述

體呈橢圓形而側扁。頭小，頭背部輪廓不特別凸出。口小，端位，上下頜各具一列扁平齒，齒固定不可動，齒緣具缺刻。背鰭及臀鰭硬棘尖銳，分別具XI棘及III棘，各鰭條皆不延長；胸鰭近三角形；尾鰭內凹，成魚呈彎月形。體淡藍色至暗褐色，體及頭具許多藍色直走縱線；緊貼著眼睛後方具一不規則之黃色斑塊及眼前具二條黃色縱帶；各鰭褐色；背鰭基部具一黑褐色紋，向後漸粗；背鰭及臀鰭鰭膜具不顯之縱帶；尾鰭具黑緣；尾柄棘溝為黑色。以前所記載之布氏刺尾鯛(/Acanthurus
bleekeri/)為本種之同種異名。
棲地
provided by The Fish Database of Taiwan
主要棲息於礁區斜坡，亦常被發現於鄰近珊瑚礁或是岩石底部之混濁水域中，是刺尾鯛科魚類中最能容忍混濁水域之魚種。以動物性浮游生物為食，成魚常可見到成群悠游於中層水域捕食浮游生物。產卵時期也有聚集成群之習性。
Elongate surgeonfish

Acanthurus mata is a marine tropical fish belonging to the family of the Acanthuridae or surgeonfishes. Its common names are elongate surgeonfish and blue-lined surgeonfish.[2]
Description
It is a medium sized fish that can reach a maximum size of 50 centimetres (20 in) length. The body has an oval shape and is compressed laterally. Like other surgeonfishes, Acanthurus mata swims with its pectoral fins. The caudal fin has a crescent shape. The mouth is small and pointed.[3] Its body is streaked with horizontal bluish lines on a brown background color although over time it is able to change colour to become grey-blue overall. A longitudinal yellow stripe runs across the eye and splits in two lines extending anterior the eye. The superior lip is also yellow.[4] The dorsal and anal fin are bluish with a yellow reflection, with the base of the latter underlined by a fine black line. A sharp erectile spine (comparable to a scalpel, thus the species name) at the base of the tail is a defensive weapon.
Distribution
This fish has a wide distribution in tropical waters going from the west part of the Indian Ocean to the archipelagos in the middle of Pacific Ocean, so it's widespread all over the Indo-Pacific.[5] It is found from the Red Sea and Gulf of Oman, south to Natal, eastwards to Society and Marquesan Islands, northwards to southern Japan, southwards to New South Wales and New Caledonia. Juveniles occur as far south as Sydney (R. Myers pers. comm. 2010). It is reported from Western Australia (Allen and Swainston 1988), south to Shark Bay. It is not known to occur from the Hawaiian Islands, Pitcairn Islands and Rapa (Randall 2001a). In 2021, the species was recently recorded off the Galápagos Islands in the Tropical Eastern Pacific.[6]
Habitat
Acanthurus mata inhabits usually steep slopes around coral reefs in depth range from 5 to 45m.[4]
Feeding
Elongate surgeonfish is a planktivore with a preference for the zooplankton.[3]
Behaviour
Acanthurus mata has a diurnal activity. It is solitary when resting on the reef but may form small aggregation in the open water during feeding.[4]
