Description
Dorsal spines (total): 9; Dorsal soft rays (total): 11-12; Anal spines: 3; Anal soft rays: 11. First spine of the anal fin is minute or imbedded. Terminal males typically have a series of partial to complete longitudinal thin blue lines on their sides. Females mainly bluish grey with fine white spotting over upper sides and a small red spot at axil of pectoral fin. Terminal males of Stethojulis strigiventer and Stethojulis bandanensis are similar, but in Stethojulis strigiventer the uppermost lateral blue streak rather than the lowermost one extends to the tail. Max length : 15.0 cm (male) ; 8.0 cm (female). Depth range 3 - 30 m.
Body moderately slender, its depth 2.9 to 3.3 times in standard length. Dorsal profile of head convex; anterior tip of head forming an acute angle; jaws and mouth small; teeth small and incisiform, none notably enlarged; canine tooth present at rearof upper jaw. Dorsal fin continuous, with IX spines and 11 soft rays; spines and anterior soft rays of similar length; anal fin with III spines and 11 soft rays; pectoral fins long, the fin base aligned at about a 30° angle to long axis, with ii unbranched and 12 or 13 branched rays; caudal fin truncate to slightly rounded. Lateral line abruptly curved below posterior portion of dorsal-fin base, with 25 pored scales. Scales reaching slightly onto bases of dorsal and anal fins; scales on thorax about 1/2 the size of those on body; head without scales.
Colour
Initial phase dark grey with upper half of body finely dotted with white speckles, lower half of body with basal portion of scales a darker grey; a bright red spot above upper base of pectoral fins; 1 to 3 (usually 2) small, blue-edged black spots midlaterally at rear of caudal peduncle. Body of terminal male blue-grey to green dorsally, abruptly pale blue ventrally, the 2 zones separated by a blue line running the length of body; a crescent-shaped bright red spot above pectoral-fin base; 4 blue lines on head, the uppermost passing along base of dorsal fin, the second stopping on nape, the third rimming upper edge of red spot and continuing onto front third of body, the fourth on lower head, then angling upward to join lateral blue line of body.
Etymology
Stethojulis: Greek, stetho, stethion = brest; literal = to prick a little breast + Greek, ioulis, a fish dealing with genera Coris or Thalassoma.
Distribution
Indo-Pacific: eastern Indian Ocean to western Australia, including the Christmas Island and Cocos-Keeling; then from Japan to New South Wales, Australia. Eastern Pacific: offshore islands in the eastern Pacific, including Clipperton, Cocos and the Galapagos islands. Range extends to Baja California during El Niño. Reported from New Caledonia.
Biology
Usually found in shallow clear water of reef flats and lagoon and seaward reefs, in areas of mixed sand, rubble and coral. Usually solitary or in small groups. Feeds mainly on demersal planktonic crustaceans and small benthic invertebrates. One of the most maneuverable and rapid swimmers of the Labridae, using rapid beats of the pectoral fins for propulsion. Not often found in markets, rarely seen in the aquarium trade.
