The extraordinary beardfish is a small bottom-dwelling fish that lives in cold waters around Antarctica. It has a long fleshy appendage on its lower jaw that helps find prey in the dark.
The extraordinary beardfish differs from other Antarctic fish with a special long appendage on its chin that acts as a sensory organ and lure. It plays an important role in the food chain of cold seas, eating small animals and serving as food for larger predators.
Immature form that undergoes metamorphosis before adulthood.
