Crested Bandfish, Lophotus guentheri Johnston 1883


Other Names: Crestfish, Unicorn Fish, Unicorn Ribbon-fish

A Crested Bandfish, Lophotus guntheri, 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 reddish to blackish long-based dorsal fin with tall anterior rays, and a short anal fin positioned just before the small caudal fin. The species has a vertical head profile, very large eyes, and an internal ink sac opening near the anus. The sac contains dark, inky liquid that may be used as a defense mechanism when the fish is threatened.

Crested Bandfish, Lophotus guentheri Johnston 1883

More Info


Distribution

Known in Australian waters from off northern New South Wales to off Cheyne Beach, Western Australia. The species is pelagic in the open ocean, in depths to 90 m.

Features

Dorsal fin 225-259; Anal fin 19-21; Pectoral fin 15-18; Vertebrae 141-152.

Feeding

Feeds on cephalopods (squids) and small fish. 

Biology

The Crested Bandfish is a poorly-known species and individuals have often washed ashore after storms.

Remarks

The species has been treated as Lophotus lacepede, L. capellei and L. guntheri in Australia, and there is confusion over the number of species that occur here. Although Craig et al. (2004) used the name L. guntheri for the south Pacific species further work may be needed to determine the identity of Australian material.

Etymology

The species is presumably 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
