Crested Bandfish, Lophotus guentheri Johnston 1883
Other Names: Crestfish, Unicorn Fish, Unicorn Ribbon-fish

A Crested Bandfish, Lophotus guentheri, that washed ashore on Bherwerre Beach just south of Jervis Bay, New South Wales, June 2020. Source: dj_maple / iNaturalist.org. License: CC By Attribution-NonCommercial
Summary:
A long, silvery-bluish ribbon-like fish becoming paler below, with a pink to reddish or blackish long-based dorsal fin with tall anterior rays, a pink pectoral fin, and a short anal fin positioned just before the small caudal fin. The species has a vertical head profile and very large eyes. It also has an internal ink sac that opens near the anus, containing a dark, inky liquid that may be used as a defence mechanism when the fish is threatened.

Crested Bandfish, Lophotus guentheri Johnston 1883
More Info
Distribution |
Off northern New South Wales to off Cheyne Beach, east of Albany, Western Australia. Elsewhere the species circumglobal in the open ocean. |
Features |
Dorsal fin 225-259; Anal fin 19-21; Pectoral fin 15-18; Gill rakers (lower limb) 7-8; Vertebrae 141-152. Body elongate, moderately deep (approx. 12-20% SL), compressed. Head moderately large (approx. 15% SL), front profile vertical or slanting steeply upwards and forwards; eyes large; mouth small, protrusible, maxilla longer than deep; teeth small, conical, narrow band in upper jaw, single row in lower jaw. Scales cycloid, small, weakly attached; lateral line straight, along middle of sides. Single low dorsal fin arising at front edge of head as short-based, tall crest supported by one to three rays, extending length of body and joining caudal fin; anal fin very small, rounded separate from, but adjacent to caudal fin; caudal fin very small, directed horizontally. Pectoral fins small, Pelvic fins minute. |
Feeding |
Feeds on cephalopods (squids) and small fishes. |
Biology |
The Crested Bandfish is a poorly-known species and individuals have often washed ashore after storms. |
Remarks |
There is confusion over the number of species of Lophotus that occur in Australian waters. It has been treated as Lophotus lacepede, L. capellei and L. guntheri in Australia. Although Craig et al. (2004) used the name L. guntheri for South Pacific species, further work may be needed to determine the identity of Australian material. |
Etymology |
The species is named for Albert Günther of the British Museum (Natural History). Although Johnston originally named the species guntheri, the correct spelling of species named for Albert Günther is guentheri. |
