Info
Eubalichthys cyanoura has numerous small brown spots on the body and a bright blue coloration on the tail of the male.
The Bluetail Leatherjacket is not often seen by divers due to their stealthiness, however juveniles have been observed under jetties in coastal bays.
Adult fish are greenish to dark brown with dark spots on the head and body, the snout and the area above the anal fin are covered with dark brown lines and spots.
The membranes of the first dorsal and caudal fins are blue in males and pale in females.
The fin rays of the filefish are greenish, females and juveniles have a mosaic pattern of large dark spots.
Adults: head and body pale green, pale brown to blackish brown, covered with closely spaced darker spots; dark brown lines and spots on snout and along anal fin base; mosaic pattern of dark brown to blackish spots often present laterally or mosaic of only pale lines; 2 whitish bars usually on throat (may be pale and difficult to see in large males).
The indentations of the first dorsal and caudal fins are pale blue in males, hyaline in females.
Juveniles: head and body sides are mosaic of large dark spots, spots develop at about 10cm lateral length.
The species was described to Dr. Barry Hutchins of the Western Australian Museum, an active supporter of the Marine Encyclopedia.
The species name "cyanoura "comes from the Greek "kyanos" (meaning dark blue) and "oura" (tail), referring to the blue tail of the males.
