Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 0; Spine anali: 0; Raggi anali molli: 0; Vertebre: 162 - 171. White to yellow with 25-30 black saddles (Ref. 3972).
Body shape (shape guide): eel-like; Cross section: circular.
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).
