Ecology of Trichonotus halstead
 
Main Ref. Clark, E. and M. Pohle, 1996
Remarks Like other sand divers, it occurs on sand slopes with strong currents at times (Ref. 48636). Lives in harems (1 male:4 or 5 females) in well-defined territories and spends more than 80% of its day perched on sand. When disturbed, it dives into the sand where it also spends the night. It feeds on benthic crustaceans and low drifting plankton (Ref. 26146).
