Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 39 - 41. Males recognized by long dorsal fin rays and large size (Ref. 48636). Under dorsal fin with 1 or 2 free pterygiophores (Ref 12934).

Found in steep sand slopes in large aggregations (Ref. 8631). Hovers above clean sandy bottoms; darts into the sand when disturbed. Usually slightly silty habitat. Usually seen resting on substrate, leaving substrate to grab prey from zooplankton floating over, or when displaying (Ref. 48636).
