Diagnostic Description
provided by Fishbase
Recognized by hinged part of dorsal fin spine. Variable in color with habitat. Greenish-yellow with diffused stripe when in seagrass environment. Pale with black stripe when found on open substrate with white sand or rubble (Ref. 48635).Description: Characterized by extremely thin or flattened and nearly transparent body; snout through eye, to base of caudal fin with dark brown to blackish stripe; horizontal first dorsal spine, projecting beyond tail tip, posterior part with movable segment; striated interorbital without groove (Ref. 90102).

Occurs in inshore waters of the continental shelf (Ref. 75154). Swims in groups among the coral reefs (Ref. 9137).
Biology
provided by Fishbase
Form schools among the spines of Diadema or staghorn corals, and feed on minute crustaceans in the zooplankton. Remarkable for their strange body shape and swimming habit: the body is encased in an armor of thin, transparent plates; they swim in synchronized groups, each fish in a vertical position with the snout pointing downwards.

描述
provided by The Fish Database of Taiwan
體延長而極側扁，體表被透明之薄骨板。頭中大；吻突出而呈管狀。眼間隔突起而無縱走溝。口端位，很小；無頜齒。背鰭第一硬棘長而尖，位於體之末緣，與體之骨板間有可動之關節，稍可移動；第二背鰭、尾鰭及臀鰭均彎向下方；胸鰭發達，側位。無側線。體側有一條顯著之黑色縱帶。
棲地
provided by The Fish Database of Taiwan
主要棲息於珊瑚礁區，常常成群躲入珊瑚枝芽或海膽棘叢中逃避敵人的追捕；游泳的姿勢以倒立較為常見，但遇到危險要迅速游動時，亦可以水平方式，頭前尾後的向前竄游。以浮游生物為食。
Aeoliscus strigatus
provided by wikipedia EN
Aeoliscus strigatus, also known as the razorfish, jointed razorfish or coral shrimpfish, is a member of the family Centriscidae of the order Syngnathiformes. This unique fish adopts a head-down tail-up position as an adaptation for hiding among sea urchin spines.[3] The razorfish is found in coastal waters in the Indo-West Pacific.[4] Its natural habitat includes beds of sea grass and coral reefs, where sea urchins are found.[5]
Description
The razorfish is easily identifiable due to its particular body shape as well as its way of moving in synchrone group head down. It is a small fish with a maximum size of 15 cm (5.9 in) long, its body is stretched ending by a long fine "beak". Its fins are considerably reduced and transparent. The dorsal surface of the razorfish is covered by protective bony plates. They extend past the end of the body and over the tail fin, which terminates in a sharp spine. A black to brown median band runs the length of the fish crossing also the eyes. The color of the body is variable with the habitat. In seagrass environment, the background color of the body can be greenish-yellow with light brown stripes. In open areas like sand patch, rubble or close to coral reef, then the body coloration occurs to be light silver with a black to brown stripe.[6] There is no known sexual dimorphism.
Ecology
The razorfish eats mainly small brine shrimp and other small invertebrates.[3][7] They have also been known to eat minute crustaceans.[8] In the wild they have been observed hiding in the spines of sea urchins, both as a defense mechanism and as a hunting mechanism. When threatened by larger fish, the razorfish darts away to a nearby sea urchin or staghorn coral[9] for protection. Razorfish hunt among sea urchin spines, especially those of the genus Diadema,[9] and wait for small invertebrates that feed on the urchins. When their prey gets close, the razorfish will dart out and try to catch its dinner.[3]
This species is oviparous and the eggs and larvae are pelagic, the juveniles settle when they attain 20 millimetres (0.79 in) in length, frequently choosing to live among the spines of Diadema sea urchins.[10]
