Ecology of Pterapogon kauderni
 
Main Ref. Allen, G.R. and R.C. Steene, 1995
Remarks Common around the jetty, in silty sand bottoms with seagrass (Enhalus acoroides). Groups were seen associated with long-spined Diadema sea urchins (Ref. 54301). Individuals of 2 to 60 hover directly above the urchins, with the younger ones about 2-3 cm SL staying closer to the urchins. The fish retreat among the spines when threatened. Probably feed on small benthic and planktonic crustaceans at night.
