Sinh học     Tự điển (thí dụ epibenthic)

Adults occur in sandy to silty bottoms of lagoons and coastal bays near coral, rubble or leaf litter shelter. Solitary or in pairs that share sandy burrows (Ref. 90102). Feed on small interstitial invertebrates by sifting mouthfuls of sand. Monogamous (Ref. 52884, 48637).
