Introduction

The Polymixiidae comprise a single genus with 10 species (Paxton 1999; Paxton et al. 2006; Nelson 2006; Eschmeyer 2011). Three species have been taken in Australian waters, and a further two unidentified species are known from off Western Australia (Williams et al. 1996).

Beardfishes are bottom dwellers on the outer shelf and upper slope to about 650 m. Crustaceans and fishes have been found in their stomachs. They are characterised by having a conspicuous hyoid barbel, ctenoid scales, subabdominal pelvic fin with 1 spine and 6 soft rays and a single dorsal fin with 4–6 spines and 26–38 soft rays.

The polymixiids were reviewed by Lachner (1955), Woods & Sonoda (1973) and Kotlyar (1984). Yamane & Okamura (1966) revised Japanese specimens and Kotlyar (1992) treated some species.
