Description

Berndt's beardfish is a deep-water fish of the beardfish family (Polymixiidae) from the Indo-Pacific. The species grows to about 47 cm and has a stocky, silvery body with large eyes and, characteristic of beardfishes, a pair of long chin barbels under the throat. It lives benthically on sandy and muddy bottoms of the continental slope at considerable depth. With its barbels it probes the bottom for small crustaceans, worms, molluscs and small fishes. Beardfishes are an ancient fish group with features of both lower and higher fishes. The species is harmless to humans.
