A Crested Bandfish purchased from Nicholas Seafood by B. Yau, September 2005 (AMS I.43718-001). The fish was caught by M. Cameron on FV Tasman Explorer at a depth of 1000 m, off Coffs Harbour, New South Wales. The two wounds were probably caused by a Cookie-cutter Shark. Image: Mark McGrouther

Introduction

The Crested Bandfish has a long, silvery, ribbon-like body that can grow to 2 m in length. Little is known of its biology.

Identification

The Crested Bandfish can be recognised by its long ribbon-like body and large eyes. It has a long-based, red dorsal fin with elongate leading rays and a short anal fin positioned just anterior to the caudal fin.

Work needs to be done on the family. The identification of the species that occurs in the south Pacific has been called into question on several occasions. It has been called Lophotus lacepede in the past. A third species, L. capellei does not occur in Australian waters.

Only two species in the family Lophotidae are currently considered to be valid in Australia; Lophotus guntheri and Eumecichthys fiski, the Unicornfish.

Habitat

The species most likely lives in deep waters.

Distribution

The Crested Bandfish occurs in all oceans. In Australia it has been recorded from scattered locations off New South Wales, Victoria, Tasmania and Western Australia.

Feeding and diet

The diet consists of squid and small fishes.

Other behaviours and adaptations

Little is known of the biology of the Crested Bandfish. It has an internal ink sac that stores a dark, inky liquid which may be used as a defense mechanism against predators.
