Inhabit lagoon and seaward reefs (Ref. 9710). Occasionally are seen under floating objects (Ref. 1602). Juveniles may travel with weed rafts in open ocean for a long time and reaching a large size. Adults are usually seen along deep coastal slopes or outer reef drop-offs in about 20 meters depth (Ref. 48637). Benthopelagic (Ref. 58302). Feed on algae, seagrass, hydrozoans, gorgonians, colonial anemones, and tunicates. Caught at the surface using a hand net (Ref. 26165).

分布

廣泛分布於世界各溫帶及熱帶海域。台灣除西部外，各地皆產。
利用

主要漁法為圍網及一支釣等，因具厚皮，食用前，通常會先去頭及剝皮，亦是俗稱剝皮魚的由來。唯因食物鰱的關係，食之可能引起中毒；或以其擬態的模樣而常被飼養於水族館中，供人欣賞，是極受歡迎之魚種。

Description
Artist representation of
A. scriptus
Aluterus scriptus is a medium size fish which can grow up to 110 cm (3.6 ft) in length.[3] The body shape looks like an elongated oval, strongly compressed. Its background body coloration is olive-brown or grey depending on its surrounding environment, irregular blue lines and spots are distributed on the body mixed with some black spots mainly on the head. The colors may quickly vary depending on background similar to an octopus's. Fish observed in the Virgin Islands might lie flat on the sand and become pure white or change to any of the other representative colors. The mouth is small and at the end of its pointed snout. Like all the Tetraodontiformes, it has no pelvic fin but has two particular dorsal spines; the first anterior one is long, slender and erectile, located just over the eyes, the second is small and not easy to see but it locks the first one when it is erected.[3] The rounded caudal fin is quite long and can be displayed as a fan.
The juveniles have a yellow with black spots body coloration.[4]
Feeding
Aluterus scriptus is omnivorous and have a large choice for its meals like small crustaceans, algae, gorgonians, sea anemones, tunicates, fire coral,[3] seagrasses and hydrozoans.[5]
Behaviour
Aluterus scriptus is diurnal and is demersal. It is solitary and shy with divers and is rarely seen with others
