More Info


Distribution

Eastern Australia, from southern Queensland, to Sydney Harbour, New South Wales. Widespread in tropical and temperate waters of the Pacific, in depths to 100 m. The species is known mostly from individuals washed ashore. Juveniles are thought to inhabit shallow waters, while adults usually live in deeper offshore waters to a depth of 100 m.

Features

Dorsal fin 46-55; Anal fin 40-43. 
Dorsal and anal fins with scaly sheaths, fins very tall; dorsal fin origin above middle of snout, fin extending to just beyond caudal-fin base, the 4th ray much stouter than other rays.

Fisheries

Commercially fished in parts of its range.

Remarks

Preyed upon by large predatory fishes such as tunas and lancetfishes.

Similar Species

Differs from the Fanfish Pteraclis velifera. in the number of vertebrae, with 45-48 (vs 51-54 in P. velifera), the number of dorsal-fin rays, 49-52 (vs 54-57 in P. velifera) and in the number of anal-fin rays, 40-44 (vs 47-50 in P. velifera).

Etymology

Pteraclis is from the Greek “ptera” (wing) and “clis” (shut), in reference to the huge dorsal and anal fins that retract into scaly sheaths.
