Biologi     Ordlista (t.ex. epibenthic)

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).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Rises to the surface to spawn. Once there, one or more males may seize a female by the back of the neck and remain attached for hours before spawning occurs.
