Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 0; Épines anales: 0; Rayons mous anaux: 0; Vertèbres: 162 - 171. White to yellow with 25-30 black saddles (Ref. 3972).
Occurs in sandy areas and seagrass beds of both lagoon and seaward reefs. Uses its stiff pointed tail to rapidly burrow backwards into the sand when frightened (Ref. 37816). Benthic (Ref. 58302). Feeds on sand-dwelling fishes and crabs and prawns. Sometimes fully exposed when searching for prey (Ref. 30874). Rises to the surface to spawn (Ref. 37816).
