More Info

Distribution	South of Esperance to off Scott Reef, Western Australia, and off Lord Howe Island in the Tasman Sea. Elsewhere, the species is known from scattered localities in the tropical, west-central Pacific, including off New Caledonia in the Coral Sea. Inhabits relatively deep reefs along continental, seamount and insular slopes.
Features	Dorsal fin X, 11-12; Anal fin III, 9. Head blunt; lower jaw protruding; snout short; premaxilla not protractile; maxillary extending to below middle of eye, ridges present, scales absent; interorbital space flat; eye large; preorbital bone relatively narrow. Teeth present on vomer. Scale rows on back parallel to lateral line; scales absent from dorsal and anal fins. Pectoral fins short, not reaching level of anus. Lower lobe of caudal fin with some rays excessively produced and filamentous in young.
Fisheries	Of minor commercial importance in parts of its range and taken mostly on hook and line.
Remarks	In Australia, this species is known from two specimens collected in Western Australian waters, and two specimens taken off Lord Howe Island in the Tasman Sea.
Etymology	The specific name is from the Latin filamentosus (= filamentous), in reference to the very elongate lower caudal-fin rays of juveniles, including the holotype.
Species Citation	Etelis filamentosus Fourmanoir 1970, Cahiers O.R.S.T.O.M. Serie Océanographique 8(2): 28, fig. 6. Type locality: off New Caledonia, stomach content [22°52'S, 162°20'E].
