Polymixia nobilis (Lowe 1836; Polymixia hollisterae Grande and Wilson 2021; 30cm) is the extant stout beardfish, a benthic taxon found below 800m. The hyoids produce the barbels. "Few groups have shifted back
and forth as frequently as this one" (Nelson, et al. 1916). Here Polymixia nests between Sargocentron and Anomalops. Each of the circumorbital bones has a laterally projecting flange. |
