description Stout Beardfish Overview
The stout beardfish (Polymixia nobilis) is a deep-sea marine fish belonging to the ancient order Polymixiiformes. It is recognized by science as one of the most primitive living lineages of acanthopterygian, or spiny-rayed, fishes. This species is native to the Western Atlantic Ocean, ranging from North Carolina through the Gulf of Mexico and into the Caribbean Sea, typically inhabiting moderate continental shelf depths. It is anatomically distinguished by a pair of prominent hyoid barbels extending from its chin, which it uses to sense and locate small benthic invertebrates in the substrate.
